Description

Touch panel structure of electrostatic capacitive touch screen using virtual pattern

The present invention relates to a touch panel structure for an electrostatic capacitive touch screen, and more particularly to a touch panel structure of an electrostatic capacitive touch screen using a virtual pattern.

Recently, in order to improve portability, different mobile terminals such as mobile phones, PDAs, and MP3 players have gradually decreased in size. In order to provide high-quality images by mobile terminals, the size of displays applied to mobile terminals has increased. In order to simultaneously meet the need to reduce the size of the mobile terminal and increase the size of the display on the mobile terminal, the touch screen method is used to allow the user to perform the input operation by himself. The touch screen method is applied to large televisions or displays such as liquid crystal displays (LCDs), plasma display panels (PDPs), organic light emitting diodes (OLEDs), and active array organic light emitting diodes (AMOLEDs).

The touch screen is a device that the user can directly input by judging the position coordinates touched by the hand of the person or by judging the letter or preset position displayed on the screen by the stylus. According to the principle of operation, the touch screen includes an electrostatic capacitive touch screen, a resistive touch screen, a surface ultrasonic touch screen, an infrared touch screen or a similar form of touch screen.

In particular, when a person's hand or an object touches the electrostatic capacitive touch screen, the conductive sensor pattern senses a change in capacitance between the other sensor pattern and the ground electrode around the conductive sensor pattern. , the touch position is converted into an electronic signal.

In this case, in order to accurately determine the touch position on the touch surface, the sensor pattern is composed of the first sensor pattern, or an X-axis direction pattern connected to each other in the first direction and in the second direction. The Y-axis direction pattern is connected to each other.

The first sensor pattern and the second sensor pattern are respectively located in different layers. For example, the first sensor pattern is located on the upper layer, and the second sensor pattern is located on the lower layer, and the dummy pattern is between the first sensor pattern and the second sensor pattern.

FIG. 1 is a schematic diagram of a layout pattern of a sensor pattern and a dummy pattern according to the prior art.

Referring to FIG. 1A, it can be seen that in the prior art, the dummy patterns 111 are located between the sensor patterns 110 in the touch panel, and the dummy patterns are not connected to each other. When a partial short circuit occurs between the sensor pattern and the dummy pattern, current flows from the sensor pattern into a virtual pattern.

Referring to FIG. 1B, it can be seen that in the prior art, the dummy patterns 111a are located between the sensor patterns 110 in the touch panel, and the dummy patterns 111b are connected to each other. When a partial short circuit occurs between the sensor pattern and the dummy pattern, the current sensor pattern flows into all of the dummy patterns.

2A and 2B are schematic diagrams illustrating a fault according to a short circuit phenomenon of a touch panel.

Referring to FIG. 2A, when the preset sensor pattern in the touch panel is touched, the capacitance change in the position is recognized by the sensors on the X-axis and the Y-axis, respectively, to determine the touch coordinates.

Referring to FIG. 2B, in the case where a partial short circuit occurs between the sensor pattern and the dummy pattern, when the position of the preset sensor pattern is touched, current flows from the sensor pattern into the dummy pattern.

In particular, in the case where the dummy patterns are not connected to each other, in the case where the dummy patterns are connected to each other, when a partial short circuit occurs between the sensor pattern and the dummy pattern, since the current flows from the sensor pattern to all the dummy patterns, the excess amount The change in capacitance hinders the identification of the touch position, so that the touch position cannot be accurately determined.

However, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein.

Therefore, the following The first element described may be referred to as a second element without departing from the teachings of the inventive concept. As used herein, the term "and/or" includes any of the associated listed items and all combinations of one or more. Various illustrative embodiments of the invention are described in detail below with reference to the drawings.

More specifically, the present invention provides a structure of a new touch panel or sensor substrate in which a plurality of dummy patterns are located between the sensor patterns, and 1) the dummy patterns are divided into a plurality of pre-patterns a virtual sub-pattern of shapes, 2) internal grids constituting the virtual pattern are regularly or irregularly disconnected from each other, or 3) an auxiliary virtual pattern located between the sensor pattern and the dummy pattern along the sensor pattern and virtual A boundary line between the patterns is spaced apart and is actually separated from the virtual pattern.

FIG. 3 is a schematic diagram of a layout pattern of a sensor pattern according to an exemplary embodiment of the invention.

As shown in FIG. 3, the inductor patterns according to the present invention are arranged to span each other, and include a plurality of first sensor patterns 110 for sensing the X-axis, and a plurality of second sensor patterns 210 for the Y-axis. induction.

For example, the first inductor pattern 110 is regularly formed in a first direction, such as a vertical direction, as a pattern responsible for sensing the X-axis, and the second inductor pattern 210 is regularly formed in a second direction, such as a horizontal direction, As a pattern responsible for sensing the Y axis.

The first sensor pattern 110 includes a plurality of first detecting portions 110a and a connecting portion 110b, and the connecting portion 110b is connected to the first detecting portion 110a, and similarly, the second sensor pattern 210 includes a plurality of second detecting portions 210a And the connecting portion 210b, the connecting portion 210b is connected to the second detecting portion 210a.

4A-4C are schematic diagrams showing a sensor portion, a connecting portion, and a dummy portion in a touch screen sensing substrate according to an exemplary embodiment of the invention.

Referring to FIG. 4A, a touch screen sensing substrate according to an exemplary embodiment of the present invention includes a plurality of first detecting portions 110a, and a plurality of first detecting portions 110a are used as electrodes, since one side of the board has a preset The pattern of directions is connected, and the joint portion 110b serves as an electrode and is connected to the detecting portion 110a by a pattern having the same or similar direction.

Referring to FIG. 4B, in the embodiment, the touch screen sensing substrate adopts a plurality of dummy patterns 111a adjacent to the first detecting portion 110a as electrodes, and the electrodes are connected by patterns having the same or similar directions to reduce dummy. The visibility of the pattern 111a.

Herein, the first detecting portion 110a and the dummy pattern serve as electrodes to sense the touch signal of the user. In the present invention, the first detecting portion 110a and the dummy pattern are made of a conductive material, and may be an opaque conductive material. .

The dummy pattern 111a serves as an electrode adjacent to or adjacent to the first detecting portion 110a, that is, a dummy electrode, which is a pattern having a shape similar to that of the first detecting portion 110a, and the dummy pattern 111a is not active. In this way, the user's touch signal or its combination will not be sensed. According to this, the first detecting portion 110a and the dummy pattern 111a are electrically insulated from each other. The reason why the dummy pattern 111a is formed on the substrate is that the first detecting portion 110a not made of the transparent electrode material is formed on the surface of the entire touch screen sensor to prevent the first detecting portion 110a from being irradiated to the outside of the touch screen sensor. The light is recognized.

In FIGS. 4A and 4B, the first detecting portion 110a and the dummy pattern 111a are linear, but the present invention is not limited thereto, and the first detecting portion 110a and the dummy pattern 111a may have many different shapes. For example, the overall shape of the first detecting portion 110a may be a diamond shape, a trapezoidal shape, and a rhombic shape.

Meanwhile, when the first detecting portion 110a and the dummy pattern 111a are formed, electrodes for transmitting the touch signals sensed by the first detecting portion 110a to an external driving circuit (not shown) may be simultaneously formed. In the present invention, since the description about the electrodes is not within the scope of the present invention, it will not be described here.

Referring to FIG. 4C, the first detecting portion 110a, the dummy pattern 111a, and the inductive connecting portion 110b of the touch screen sensing substrate are used as electrodes according to an embodiment of the present invention, and are connected by a pattern identical or similar to a preset direction. In the case where the virtual joint portion is included, the virtual joint portion also functions as an electrode and is connected by a pattern identical or similar to the preset direction.

In this embodiment, the pattern has a unique continuous pattern of a predetermined direction, and in this embodiment, as shown in FIG. 3, is a grid-like pattern, in which the line segments in the pattern are preset. The direction is through each other.

In this embodiment, for the repeatability of the pattern, the same or similar patterns may be repeated circular and repeated and identical geometric patterns, or repeated circular and repeating and the error range is preset by the software. Geometric patterns. Accordingly, in the present embodiment, the electrode pattern of the first detecting portion 110a, the electrode pattern of the dummy pattern 111a, and the electrode pattern of the dummy connecting portion 111b are all the same, wherein the sensing of the first detecting portion 110a and the dummy pattern 111a is connected In the case where the connecting portion 110b and the virtual connecting portion 111b exist, the visibility of the first detecting portion 110a can be recognized by the user.

The pattern has a unique continuous pattern of preset directions, and a portion of the pattern is broken to form the inductor portion 110 and the dummy pattern 111a. When the first detecting portion 110a, the dummy pattern 111a, and the inductive connecting portion 110b are present, when one side of the pattern of the virtual connecting portion 111b is turned on, the partial pattern is broken.

As described above, the disconnection between the pattern on the boundary of the first detecting portion 110a and the dummy pattern 111a indicates that the first detecting portion 110a and the dummy pattern 111a are electrically insulated from each other, and, as shown in FIG. 5, the first The open edges formed by the disconnection of the patterns of the detecting portion 110a and the dummy pattern 111a indicate the electrodes whose edges are not connected to the edges. Fig. 5 is an enlarged view of a portion shown in Fig. 4B. Referring to Fig. 5, since the edge is opened to connect the edge electrodes, the problem of continuity disappearing or being cut off can be solved. However, in practice, the edges are separated from each other by a small interval, so that the user still considers the electrodes to be continuous in recognition, so that the visibility of the first detecting portion 110a can be reduced.

In this embodiment, the patterns may be grid-like patterns, and the line segments in the patterns traverse each other in a predetermined direction, as shown in FIGS. 4A-4C. In the present invention, the mesh may be a conspicuous mesh and an amorphous mesh. The line segments in the patterns are completely formed by crossing each other in a predetermined direction to indicate a crystalline or mesh-like mesh.

Line segments that traverse each other in the pattern may have line widths that are the same or have a predetermined similarity and intervals between the line segments. In this embodiment, the line widths of the same or with the preset similarity and the interval between the line segments represent that the line segments have preset values, as shown in Table 1, to obtain a preset fill factor.

In this embodiment, the grid pattern of the line segments passing through each other may be inclined at a predetermined inclination angle. Referring to FIG. 6, the grid pattern formed by the line segments in the embodiment is inclined at an angle of 45 degrees with respect to the horizontal axis, and by increasing the ratio of the electrodes for sensing the touch input per unit area, such tilting The shape is to increase the accuracy of the induction. Since the pattern having the preset direction and the other different patterns interfere with each other, the preset tilt angle is preset to avoid the occurrence of the ripple effect. In this embodiment, since the substrates having different sensing touch directions are stacked, the mutual patterns between the different patterns are The interference may form mutual interference between the electrode patterns on the substrate, or, since the image information display unit includes a plurality of pixels to display image information, mutual interference between different patterns may cause interference between the patterns.

The ripple effect is a common natural interference phenomenon that occurs when two separate periodic patterns are stacked at a predetermined angle. The ripple phenomenon represents the intensity variation of the intensity, such as the waveform, ripple, and beam wave, which are laminated with the image displayed on the screen.

When the embossed shape of the mold is a quadrangle, the shape of the intaglio printing pattern formed on the resin layer 100a is a quadrangle, and when the embossed shape of the mold is a triangle, the shape of the intaglio printing pattern formed on the resin layer 100a is a triangle. When the embossed shape of the mold is trapezoidal, the shape of the intaglio printing pattern formed on the resin layer 100a is a trapezoid. The line width of the gravure printing on the resin layer 100a is in the range of 1 μm to 10 μm, and the depth is in the range of 1 μm to 10 In the range of μm, and the interval between the line segments is in the range of 200 μm to 600 μm, but it is limited to the present embodiment, and the above numerical range can be modified as needed, and is not limited herein. The resin layer 100a may be an ultraviolet curable resin or a thermosetting resin.

The electrode layer 112 is formed by filling a conductive material into the intaglio plate, and in the case where the first sensor portion 100, the dummy pattern 111, the inductive connection portion 110b, and the virtual connection portion exist, a virtual connection portion (not shown) is formed in On the electrode layer 112. Here, the conductive material may include copper (Cu), silver (Ag), aluminum (Al), nickel (Ni), chromium (Cr), nickel-phosphorus alloy (Ni-P), or the like.

9A-9C are first schematic views showing the shape of a touch panel according to an exemplary embodiment of the invention.

As shown in FIGS. 9A-9C, according to the present embodiment, the first inductor pattern 110 and the second inductor pattern 210 are located in different layers. For example, the first sensor pattern 110 is located on the first inductor portion 100 as an upper layer, and the second inductor pattern 210 is located on the second inductor portion 200 as a lower layer.

Here, an adhesive layer (not shown) is inserted between the first inductor portion 100 and the second inductor portion 200, and for the convenience of description, it is only mentioned and will not be explained.

In this case, as shown in FIG. 9A, the dummy patterns 111 and 211 are respectively located between the first sensor pattern 110 and the second sensor pattern 210, and the dummy pattern fills the blank space between the sensor patterns, and The image sensor pattern has the function of sensing the touch position.

For example, the first dummy patterns 111 are alternately formed between the first inductor patterns 110, and the first dummy patterns 111 are alternately formed in a blank area corresponding to the position of the second inductor pattern 210.

Likewise, the second sensor patterns 211 are alternately formed between the first sensor patterns 211, and the second dummy patterns 211 are alternately located in the blank areas corresponding to the positions of the second sensor patterns 210.

As shown in FIG. 9B, the first dummy patterns 111 are alternately formed between the first sensor patterns 110, and the dummy patterns are not located between the second inductor patterns 210.

Of course, as shown in FIG. 9C, on the other hand, the second dummy patterns 211 are only located between the second inductor patterns 210, and the dummy pattern portions are located between the first inductor patterns 110.

The dummy pattern has the same size as the inductor pattern and is made of the same material. The dummy patterns are not connected to other adjacent dummy patterns, and if necessary, the dummy patterns are joined to each other.

10A-10C are second schematic views showing the shape of a touch panel according to an exemplary embodiment of the invention.

Referring to FIG. 10A, a touch panel according to the present invention includes a first inductor portion 100 and a second inductor portion 200. The first sensor pattern 110 and the first dummy pattern 111 are alternately arranged in the first inductor portion. In 100, the second sensor pattern 210 and the second dummy pattern 211 are alternately arranged in the second inductor portion 200. That is, the dummy patterns are respectively located in the blank space between the first sensor pattern 110 and the blank space between the second sensor patterns 210.

In this case, the separation distance between the sensing pattern and the dummy pattern is in the range of 5 μm to 30 μm, especially 15 μm or more. For example, the separation distance between the first sensor pattern and the first dummy pattern or the separation distance between the second sensor pattern and the second dummy pattern is 15 μm.

Referring to FIG. 10B, the touch panel according to the present invention includes a first inductor portion 100 and a second inductor portion 200. The first inductor pattern 110 and the first dummy pattern 111 are alternately arranged in the first inductor portion 100. The second sensor pattern 210 is arranged in the second inductor portion 200. That is to say, the dummy patterns are only located in the blank space between the first sensor patterns 110, and are not located in the blank space between the second sensor patterns 210.

Referring to FIG. 10C, in the touch panel of the present invention, the dummy patterns are not located in the blank space between the first sensor patterns 110, but only in the blank areas between the second sensor patterns 210.

In this case, in the present invention, the dummy pattern located between the sensor patterns is formed and divided into a plurality of virtual sub-patterns having a predetermined shape, and the method of dividing includes, for example, 1) a method of dividing the dummy pattern, A method of making a virtual sub-pattern have the same shape as the overall outer shape and having the same area, 2) dividing the virtual pattern such that the virtual sub-pattern has a shape different from the overall outer shape and has the same area, and 3) dividing the dummy pattern The method according to the virtual cutting pattern, between the line segment between the virtual cutting patterns and the grid in the virtual pattern, the virtual sub-pattern has a preset angle, and 4) the method of dividing the virtual pattern, regularly or irregularly disconnected A grid in a virtual pattern, or other similar method.

When the sensor pattern and the dummy pattern are partially short-circuited, current flows only from the sensor pattern into the virtual sub-pattern corresponding to the virtual pattern that is short-circuited, and the division through the dummy pattern can prevent current from flowing into the entire dummy pattern, thereby ensuring stable function. And minimize the dielectric constant of the current flowing into the dummy pattern by the sensor pattern to improve the operation of the sensor.

11A-11B are first schematic views showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIGS. 11A-11B, in the present invention, each of the dummy patterns located between the sensor patterns is divided into a plurality of dummy sub-patterns having a predetermined shape, and by interrupting a partial continuous pattern of the dummy patterns. The plurality of dummy sub-patterns are cut to have the same shape as the overall outer shape and the plurality of dummy sub-patterns have the same area.

In FIG. 11A, the broken lines of the dummy patterns 111 and the meshes in the dummy patterns are parallel to each other.

In FIG. 11B, the broken line of the dummy pattern 111 and the mesh in the dummy pattern are parallel to each other to have a predetermined angle.

In other words, the virtual pattern according to the present invention is equally cut into a plurality of virtual sub-patterns, the virtual sub-patterns having the same shape as the overall outer shape regardless of the mesh direction of the virtual patterns. For example, the virtuality of the quadrilateral The pattern 111 is cut into quadrilateral dummy sub-patterns 111a, 111b, 111c, 111d, 111e, 111f, 111g, 111h, and 111i.

As previously described in FIG. 11B, the dummy pattern is formed such that the broken lines and the grid in the virtual pattern have a predetermined angle, thereby avoiding the generation of an alternating ripple phenomenon.

Since the dummy pattern is cut into a plurality of dummy sub-patterns by breaking a part of the dummy pattern, one of the edges of the cut virtual sub-pattern is opened.

A portion of the pattern on the boundary of the virtual sub-pattern is broken such that the dummy sub-patterns are electrically insulated from each other, and the edge of the virtual sub-pattern that is opened by being broken represents that the edge is not connected to the edge electrode. Since the edge of the virtual sub-pattern is open to connect the edge electrodes, the problem of continuity disappearing or being cut off can be solved. In reality, however, the edges are separated from each other by a small interval, so as a whole, the user still believes that the electrodes are continuous in recognition.

In this case, as in the present embodiment, when the virtual joint portion does not exist, the outer shape of the virtual pattern is accurately determined, but when the virtual joint portion exists, since the outer shape of the virtual pattern is not accurately determined, the virtual The portion between the joint portion and the virtual pattern needs to be cut correctly to define the outer shape of the virtual pattern.

12A-12B are second schematic views showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIGS. 12A to 12B, in the present invention, each of the dummy patterns located between the sensor patterns is formed to be cut into a plurality of dummy sub-patterns having a predetermined shape, and by breaking the dummy pattern In a partial continuous pattern, the virtual sub-pattern is cut into a shape different from the outer shape but has the same area.

Shown in Fig. 12A is a hexagonal virtual pattern 111 in an uncut state.

In FIG. 12B, the hexagonal dummy pattern 111 is cut to form a virtual sub-pattern having a shape different from the outer shape, but the virtual sub-patterns are equal in area to each other.

For example, as shown in FIG. 12A, when the area of the hexagonal dummy pattern 111 is 90, as shown in FIG. 12B, the shape is different from the nine virtual sub-patterns 111 of the hexagon, The area of each of 111b, 111c, 111d, 111e, 111f, 111g, 111h, and 111i is 10.

As shown in FIG. 12B described above, the dummy pattern is formed between the grid and the broken line in the virtual pattern and has a predetermined angle, thereby avoiding the occurrence of interactive ripple phenomenon.

By breaking a portion of the dummy pattern, the virtual pattern is cut into a plurality of dummy patterns, and the edges of each of the cut virtual sub-patterns are opened.

13A-13B are third schematic views showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIGS. 13A-13B, in the present invention, each of the dummy patterns located between the inductor patterns forms a plurality of dummy sub-patterns having a predetermined shape, and by breaking a partial continuous pattern of the dummy patterns, These virtual patterns are cut to have a different shape than the overall outer shape.

In FIG. 13A, the dummy patterns are cut such that the line segments in the virtual cut pattern 130 and the mesh in the dummy pattern 111 are parallel to each other.

In FIG. 13B, the dummy patterns are cut such that the line segments in the virtual cut pattern 130 and the mesh in the dummy pattern 111 are not parallel to each other.

In this case, in the present invention, with the virtual cut pattern 130, the dummy pattern is cut such that the line segments in the virtual cut pattern 130 and the mesh in the dummy pattern are parallel to each other or non-parallel to each other and have a predetermined angle. The dummy pattern is cut such that at least one of the virtual sub-patterns of the cut has a shape different from the overall outer shape and has a different area.

As shown in the foregoing FIG. 13B, a virtual pattern having a preset angle is formed between the mesh of the virtual pattern and the broken line, thereby avoiding the occurrence of interactive ripple phenomenon.

The meshes in the dummy pattern are cut and not parallel to each other to form a virtual sub-pattern, thereby avoiding ripples and effectively improving visibility.

By breaking a portion of the dummy pattern, the virtual pattern is cut into a plurality of virtual sub-patterns, and the edges of each of the cut virtual sub-patterns are opened.

Here, the present invention describes the cutting principle of the virtual cut pattern using the virtual cut pattern, and the virtual cut pattern can be applied to FIGS. 11A to 12B.

14A-14B are fourth schematic views of shapes of a dummy pattern according to an exemplary embodiment of the present invention.

As shown in FIGS. 14A-14B, in the present invention, each of the dummy patterns located between the sensor patterns is cut into a plurality of preset forms, and the disconnection of a portion of the continuous pattern through the dummy patterns is cut to regularly Or irregularly disconnect the mesh in the virtual pattern within the preset range.

The length of the dummy sub-pattern is regularly or irregularly formed between 0.3 mm and 0.5 mm.

In FIG. 14A, by regularly breaking the grid in the dummy pattern 111 within the preset range, the dummy pattern is cut and the lengths of the broken lines are equal.

For example, the disconnection length Lx in the horizontal direction and the disconnection length Ly in the vertical direction are identical to each other.

In FIG. 14B, by irregularly breaking the grid in the dummy pattern 111 within the preset range, the dummy pattern is cut, and the lengths of the broken lines are not equal to each other.

Of course, the lengths of the broken lines in the preset range may be different from each other.

For example, the broken lengths Lx1 and Lx2 or Ly1 and Ly2 in the horizontal direction or the vertical direction are different from each other.

By breaking the partial virtual pattern, the virtual pattern is cut into a plurality of virtual sub-patterns, and the edges of each virtual sub-pattern are opened.

As shown in the aforementioned FIGS. 11A to 14B, the dummy pattern is cut into a plurality of dummy sub-patterns, and each of the cut virtual sub-patterns forms five unit grids or more to more effectively improve the visibility.

In this case, in the present invention, the dummy pattern is located between the sensor patterns, and an auxiliary dummy pattern may be additionally formed between the sensor pattern and the dummy pattern to follow the boundary between the sensor pattern and the dummy pattern. Separated by a preset distance and actually separated from the virtual pattern. The auxiliary virtual pattern can also be cut if necessary.

FIG. 15 is a fifth schematic diagram showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

Between 111, a plurality of auxiliary dummy patterns may be formed between the sensor pattern and the dummy pattern, if necessary.

Only the dummy pattern is described in this embodiment, and the cut virtual pattern and the virtual joint portion are not mentioned, but the virtual pattern includes the virtual joint portion.

In this case, the auxiliary dummy pattern 112 is formed along the boundary between the sensor pattern 110 and the dummy pattern 111, and is separated from each of the sensor pattern 110 and the dummy pattern 111 by a predetermined distance. In other words, the auxiliary dummy pattern 112 is separated from the sensor pattern 110 on one side by a predetermined distance and separated from the dummy pattern 111 on the other side by a predetermined distance.

The auxiliary dummy patterns 112 are formed such that the distance separated from the inductor pattern 110 and the distance separated from the dummy pattern 111 are the same or different from each other.

Since the auxiliary dummy patterns 112 formed as described above are separated by a predetermined distance along the peripheral lines of the corresponding sensing patterns 110, the auxiliary dummy patterns 112 have the same shape as the peripheral lines of the corresponding sensor patterns 110.

The auxiliary dummy pattern 112 is formed in a strip shape along a boundary between the inductor pattern 110 and the dummy pattern 111. The auxiliary dummy pattern 112 is formed along a boundary between the sensor pattern 110 and the dummy pattern 111, wherein an auxiliary dummy pattern 112 is formed on the same line segment in the same direction, for example, the same x in the same X-axis direction The coordinates are the same y coordinates in the same Y-axis direction.

Of course, the auxiliary dummy patterns 112 on the same line segment in the same direction may form a continuous pattern, but need not be limited thereto, and may be cut if necessary. That is, the auxiliary dummy pattern 112 can be cut into a plurality of auxiliary dummy patterns 112 by breaking a portion of the continuous pattern.

The virtual pattern 111 is formed by regularly or irregularly breaking the mesh constituting the dummy pattern, and the dummy pattern is formed or cut into a plurality of preset shapes.

The source of each virtual pattern 111 and the edge of the auxiliary virtual pattern are opened.

For example, a partial pattern on the boundary between the dummy pattern 111 and the auxiliary dummy pattern 112 is broken, so that the dummy pattern 111 and the auxiliary dummy pattern 112 are electrically insulated from each other. The open edge by breaking the pattern of each of the dummy pattern 111 and the auxiliary dummy pattern 112 formed represents that the edge is not connected to the edge electrode.

FIG. 16 is a schematic diagram of a layout pattern of an auxiliary virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIG. 16, the auxiliary dummy pattern is formed along the boundary between the inductor pattern 110 and the dummy pattern 111, and is spaced apart from the sensor pattern 110 on one side by a predetermined distance d1. Here, the distance d1 from the inductor pattern 110 is 30 μm or less.

On the other hand, the auxiliary dummy pattern 112 is formed on the other side and spaced apart from the dummy pattern 111 on the other side by a predetermined distance d2. Here, the distance d2 from the dummy pattern 111 is 20 μm or less.

The auxiliary dummy patterns 112 are formed such that the distance from the inductor pattern 110 and the distance from the dummy pattern 111 are the same or different from each other.

The auxiliary dummy patterns 112 are formed in a strip shape and formed between the inductor pattern 110 and the dummy pattern 111, and the thickness w has a predetermined size. Here, the thickness may be 100 μm or less.

FIG. 17 is a sixth schematic diagram showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIG. 17, in the present invention, when the virtual joint portion is formed between the dummy patterns, the dummy pattern 111 is located between the sensor patterns 110, and the auxiliary dummy pattern 112 is further formed in the sensor pattern 110 and the dummy pattern. Between 111.

In the present invention, the dummy pattern 111a and the virtual joint portion 111b are actually separated from each other by a predetermined distance.

In this case, the auxiliary dummy pattern 112 is formed along the boundary between the sensor pattern 110 and the dummy pattern 111, and is separated from each of the sensor pattern 110 and the dummy pattern 111 by a predetermined distance. In other words, the auxiliary dummy pattern 112 is spaced apart from the sensor pattern 110 on one side by a predetermined distance and spaced apart from the pattern 111 on the other side by a predetermined distance.

The auxiliary patterns 112 are formed such that the distance from the sensor pattern 110 and the distance from the dummy pattern 111 are the same or different from each other.

Since the auxiliary dummy pattern 112 formed as described above is spaced apart from the sensor pattern 110 by a predetermined distance along the peripheral line of the corresponding sensor pattern 110, the auxiliary dummy pattern 112 has the same shape as the peripheral line of the corresponding sensor pattern 110.

The auxiliary dummy pattern 112 is formed along a boundary between the inductor pattern 110 and the dummy pattern 111, and is in a strip shape. Since the auxiliary dummy picture 214 is formed along the boundary between the sensor pattern 110 and the dummy pattern 111, an auxiliary dummy pattern may be formed on the same line segment in the same direction. For example, the same x coordinate in the X-axis direction or the same y-axis coordinate in the Y-axis direction.

Of course, the auxiliary dummy patterns 112 on the same line segment in the same direction form a continuous pattern, but need not be limited thereto, and can be cut if necessary. That is, a portion of the continuous pattern is broken and cut into a plurality of auxiliary dummy patterns 112.

The virtual pattern 111 is formed by regularly or irregularly breaking the mesh constituting the dummy pattern, and the virtual pattern is cut into a plurality of preset forms.

The edges of each of the dummy patterns 111 and the auxiliary dummy patterns are opened. Of course, the edge of the virtual joint portion 111b separated from the dummy pattern 111 is opened.

For example, a partial pattern between the dummy pattern 111 and the auxiliary dummy pattern 112 is broken, so that the dummy pattern 111 and the auxiliary dummy pattern 112 are electrically insulated from each other. The opening of the edge of the pattern of each of the dummy pattern 111 and the auxiliary dummy pattern 112 by opening means that the edge is not connected to the edge electrode.

18A-18B are seventh schematic views showing the shape of a virtual pattern according to an exemplary embodiment of the present invention.

As shown in FIG. 18A, in the present invention, when the dummy connection portion is not formed between the dummy patterns, the dummy pattern 111a is located between the sensor patterns 110, and the auxiliary dummy pattern 112 is further formed in the sensor pattern 110 and Between the dummy patterns 111a.

For example, when the inductive joint portion is not formed, the interval between the inductor patterns 110 is smaller than the interval between the inductor patterns described in FIGS. 15 and 17.

In this case, the auxiliary dummy pattern 112 is formed along the boundary between the sensor pattern 110 and the dummy pattern 111a, and is spaced apart from each of the sensor pattern 110 and the dummy pattern 111a by a predetermined distance. In other words, the auxiliary dummy pattern 112 is spaced apart from the sensor pattern 110 on one side by a predetermined distance and spaced apart from the dummy pattern 111a on the other side by a predetermined distance.

The auxiliary dummy patterns 112 are formed such that the auxiliary dummy patterns 112 are spaced apart from the sensor pattern 110 and spaced apart from each other by the virtual pattern 111a by the same or different distances from each other.

Since the auxiliary dummy pattern 112 formed in the foregoing is separated from the sensor pattern 110 by a predetermined distance along the peripheral line of the corresponding sensor pattern 110, the auxiliary dummy pattern 112 has the same shape as the peripheral line of the corresponding sensor pattern 110.

The auxiliary virtual shape 112 is in the form of a strip and is formed along a boundary between the inductor pattern 110 and the dummy pattern 111a. Since the auxiliary virtual shape 112 is formed along the boundary between the inductor pattern 110 and the dummy pattern 111a, an auxiliary dummy pattern may be formed on the same line segment in the same direction, for example, the same x coordinate in the X-axis direction or It is the same y coordinate in the Y-axis direction.

Of course, the auxiliary dummy patterns 112 on the same line segment in the same direction form a continuous pattern, but need not be limited thereto, and can be cut if necessary. That is, a portion of the continuous pattern is broken and cut into a plurality of auxiliary dummy patterns 112.

The virtual pattern 111a is formed and cut into a plurality of preset forms by regularly or irregularly breaking the mesh constituting the virtual pattern.

The edges of each of the dummy patterns 111 and the auxiliary dummy patterns 112 are opened.

For example, a partial pattern located on a boundary between the dummy pattern 111 and the auxiliary dummy pattern 112 is broken, so that the dummy pattern 111 and the auxiliary dummy pattern 112 are electrically connected to each other. insulation. By breaking, the edges of the pattern of each of the dummy patterns 111 and the auxiliary dummy patterns 112 are opened to indicate that the edges are not connected to the edge electrodes.

As shown in FIG. 18B, in the present invention, when the virtual joint portion is not formed between the dummy patterns, the dummy pattern 111a is located between the sensor patterns 110, and the auxiliary dummy pattern 112 is further formed on the sensor pattern 110 and Between the dummy patterns 111a.

For example, when the virtual joint portion is not formed, the interval between the inductor patterns 110 may be smaller than the interval between the inductor patterns shown in Figs.

In this case, the auxiliary dummy pattern 112 is formed along the boundary between the sensor pattern 110 and the dummy pattern 111a, and is separated from each of the sensor pattern 110 and the dummy pattern 111a by a predetermined distance. In other words, the auxiliary dummy pattern 112 is separated from the sensor pattern 110 on one side by a predetermined distance and is also separated from the dummy pattern 111a of the other side by a predetermined distance.

The auxiliary dummy patterns 112 are formed such that the separation distance from the sensor pattern 110 and the separation distance of the dummy patterns 110a are the same or different.

Since the auxiliary dummy pattern 112 formed as described above is separated by a predetermined distance along the peripheral line of the corresponding dummy pattern 111a, the auxiliary dummy pattern 112a and the peripheral line of the corresponding dummy pattern 111a have the same shape.

The auxiliary dummy pattern 112 is formed in a strip shape along the peripheral line of the dummy pattern 111a. Since the auxiliary dummy pattern 112 is formed along the peripheral line of the dummy pattern 111a, an auxiliary dummy pattern 112 is formed to surround the outside of each of the dummy patterns 111a. That is, the auxiliary dummy pattern 112 is actually separated from the dummy pattern 111a.

Of course, the auxiliary dummy patterns 112 surrounding the dummy patterns are formed as a continuous pattern, but the invention is not limited thereto, and may be divided if necessary. That is, a portion of the continuous pattern is broken to be cut into a plurality of auxiliary dummy patterns 112.

The virtual pattern 111a is formed by regularly or irregularly breaking the mesh constituting the dummy pattern, and the dummy pattern is cut into a plurality of preset forms.

The edges of each of the dummy patterns 111a and the auxiliary dummy patterns 112 are opened.

For example, a partial pattern on the boundary between the dummy pattern 111a and the auxiliary dummy pattern 112 is broken, so that the dummy pattern 111a and the auxiliary dummy pattern 112 are electrically insulated from each other. Opening the edges of the pattern of each of the dummy patterns 111a and the auxiliary dummy patterns 112 by breaking means that the edges are not connected to the edge electrodes.

For example, the present invention shows an example in which a first sensor portion includes a first sensor pattern to sense an X axis and a second sensor portion includes a second sensor pattern to sense a Y axis, and when the first sensor portion When the second sensor portions are adhered to each other, the dummy patterns having different shapes are applied to the formation of the touch screen sensor, but the invention is not limited thereto. The invention is applied to a sensor of a touch screen to arrange a first sensor pattern for sensing an X-axis coordinate and a second sensor pattern for sensing a Y-axis coordinate on a surface of a single substrate.

Of course, in the foregoing example, the first sensor pattern and the second sensor pattern are both formed on the surface of the single substrate, but the invention is not limited thereto, and obviously, the first sensor pattern and the second The sensor patterns are formed on the same substrate in different forms.

For example, according to an embodiment of the present invention, dummy patterns having different shapes are applied to the touch screen sensor such that the first sensor pattern formed in the first direction and the second sensor formed in the second direction The patterns are arranged on both sides of the surface of the single substrate, respectively.

FIG. 19 is a schematic diagram of a configuration of a touch screen sensor according to another exemplary embodiment of the present invention.

As shown in FIG. 19, the touch screen sensor according to the present invention includes a first inductor portion 100, and wherein the first inductor portion 100 has an array of first inductor patterns 110 to sense the X-axis on the substrate. The coordinates, and the second sensor pattern 210 are arranged to sense the Y-axis coordinates on the substrate.

In this case, it is assumed that the first sensor pattern is referred to as a sensing electrode to sense the touch signal, and the second sensor pattern is electrically separated from the first sensor pattern and is referred to as a driving electrode to sense the driving signal.

Each of the plurality of sensing electrodes is located on the sensing strip extending in the first direction, and each of the plurality of driving electrodes is located in a second direction across the first direction. Here, the first direction represents the horizontal direction or the X-axis direction, and the second direction represents the vertical direction or the Y-axis direction.

For example, the second inductor patterns 210 for sensing the Y-axis extend in the horizontal direction and are spaced apart from each other by a predetermined distance in the vertical direction. The plurality of first sensor patterns 110 for sensing the X-axis are adjacent to the second sensor pattern 210 in parallel, and are spaced apart from each other by a predetermined distance in the direction of the water booth.

That is, a plurality of first sensor patterns 110 are disposed in parallel with each of the second sensor patterns 210.

The sensing region including one of the sensing electrodes and the plurality of driving electrodes is formed. However, the present invention is not limited thereto and may be formed in different compositions.

The wiring electrode 400 is connected to each of the first inductor pattern 110 and the second inductor pattern 210 provided as described above. Here, the wiring electrode 400 is configured to transmit the touch signals sensed by the first sensing pattern 110 and the second sensing pattern 210 to an external driving circuit (not shown).

The dummy pattern 111 is formed between the first inductor pattern 110 or the second inductor pattern 210 and the wiring electrode 400.

The size of the virtual pattern will vary depending on the size of the space. The shape of the dummy pattern 111 may be similar to or the same as the first sensor pattern 110 or the second sensor pattern 210.

A plurality of sensing electrodes are disposed on the same surface of the substrate to form a single layer structure.

In this case, when the first sensor pattern and the second inductor pattern are formed on a substrate, the first inductor pattern and the second inductor pattern are composed of only a mesh, for the reason of indium tin oxide ( ITO) is inelastic and therefore cannot be used on an elastic substrate On the other hand, the metal mesh is elastic and can be used in medium and large areas, and has a faster reaction rate than indium tin oxide (ITO).

When the first sensor pattern and the second sensor pattern are formed on a substrate, the dummy pattern is formed because the corrugation phenomenon occurs when the metal mesh is composed, and the dummy pattern formed in the blank space can be used to avoid this phenomenon. .

Since the density of the substantially different patterns will cause the pattern to be recognized, the dummy pattern is formed in the blank space to prevent the pattern from being recognized due to the calender pattern.

For example, the dummy pattern 111a2 has a larger width than the dummy pattern 111a1, and as the interval between the inductor patterns 110, 210 and the wiring electrode 400 increases, the width of the dummy pattern 111 also increases.
