Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.

1 is an exploded perspective view of a liquid crystal display according to an exemplary embodiment of the present invention.

As illustrated, the liquid crystal display device includes a liquid crystal panel 110 and a backlight unit 120, and includes a support main 130 for modularizing the liquid crystal panel 110 and the backlight unit 120.

Looking at each of these in more detail, the liquid crystal panel 110 plays a key role in image expression, the first substrate 112 and the second substrate bonded to each other with a liquid crystal layer (not shown) therebetween. 114.

In this case, although not shown in the drawing, a plurality of gate lines and data lines intersect each other and a pixel is defined on an inner surface of the first substrate 112, which is commonly referred to as a lower substrate or an array substrate, and a thin film transistor is formed at each intersection point. (thin film transistor: TFT) is provided and is connected one-to-one with the transparent pixel electrode formed in each pixel.

On the inner surface of the second substrate 114 called an upper substrate or a color filter substrate, color filters of red (R), green (G), and blue (B) And a black matrix for covering the gate lines, the data lines, and the thin film transistors. In addition, color filters of red (R), green (G), and blue (B) colors and transparent common electrodes covering the black matrix are provided.

In addition, polarizing plates (not shown) for selectively transmitting only specific light are attached to the outer surfaces of the first and second substrates 112 and 114, respectively.

In this case, the pad region is additionally provided in the first substrate 112 as compared with the second substrate 114, so that the area of one edge is larger. Accordingly, a driving circuit 115 for applying signals to a plurality of gate lines and data lines is formed in the pad region, which is one edge of the first substrate 112.

This structure is referred to as a chip on glass (COG) type liquid crystal panel 110, and the COG method directly uses the anisotropic conductive film (not shown) to directly drive the driving circuit 115 on the first substrate 112. As a method of adhering, the ratio of the liquid crystal panel 110 to the liquid crystal display device can be increased.

The driving circuit 115 is a plurality of gate and data driving circuits, and each gate and data driving circuit 115 is connected to a gate and a data line (not shown) on the first substrate 112, respectively.

In addition, the gate and data driving circuit 115 is connected to the FPC 140 for outputting various signal voltages.

A plurality of wiring patterns (not shown) connected to the data and gate driving circuit 115 are arranged at one edge of the FPC 140, and are bonded to the liquid crystal panel 110 via an anisotropic conductive film (not shown). .

In addition, a plurality of LEDs 129 are mounted on the rear surface of the FPC 140 of the present invention at regular intervals, and the FPC 140 is flipped to the rear surface of the backlight unit 120 in the modularization process of the liquid crystal display device. The plurality of LEDs 129 mounted on the FPC 140 may face the light incident surface 123a of the light guide plate 123 of the backlight unit 120 positioned on the rear surface of the liquid crystal panel 110. We will discuss this in more detail later.

When the thin film transistor selected for each gate line is turned on by the on / off signal of the gate driver circuit, the liquid crystal panel 110 transmits the signal voltage of the data driver circuit to the corresponding pixel electrode through the data line. The arrangement direction of the liquid crystal molecules is changed by the electric field between the pixel electrode and the common electrode, indicating a difference in transmittance.

In addition, the liquid crystal display according to the present invention is provided with a backlight unit 120 for supplying light to the back of the liquid crystal panel 110, so that the difference in transmittance represented by the liquid crystal panel 110 is expressed to the outside.

The backlight unit 120 includes a plurality of LEDs 129 mounted on the FPC 140, a white or silver reflector 125, a light guide plate 123 mounted on the reflector 125, and an upper portion thereof. The optical sheet 121 is included.

Here, as described above, the plurality of LEDs 129 are mounted on the FPC 140 that is bent and closely contacted to the rear surface of the backlight unit 120, wherein the FPC 140 includes a plurality of LEDs 129 on the light guide plate. It is bent to face the light incident surface 123a of 123.

Therefore, the plurality of LEDs 129 are positioned at one side of the light guide plate 123 to face the light incident surface 123a of the light guide plate 123.

As such, the FPC 140 is bent to the rear surface of the backlight unit 120 to be in close contact with each other, thereby mounting a plurality of LEDs 129 on the FPC 140, thereby providing a separate PCB for mounting the plurality of LEDs 129 ( Not shown).

As a result, the process cost can be reduced by eliminating the PCB (not shown), and the thickness and weight of the liquid crystal display device can be reduced by the thickness and weight occupied by the conventional PCB (not shown).

In particular, the FPC 140 of the present invention is characterized in that the light leakage and light loss prevention region (143: hereinafter, referred to as light leakage prevention region) is further provided.

That is, the liquid crystal display of the present invention is formed so as to cover a part of the rear surface of the reflector plate 125 through the light leakage preventing region 143 of the FPC 140 which is bent and adhered to the rear surface of the backlight unit 120.

Through this, the light guide plate 123 may be prevented from being exposed to the outside, thereby preventing light leakage and light loss from being generated by the light guide plate 123 exposed to the outside. We will discuss this in more detail later.

At this time, the plurality of LEDs 129 emits white light toward the light incident surface 123a of the light guide plate 123, including an LED chip (not shown) that emits all the colors of RGB or emits white light. In addition, the plurality of LEDs 129 emit light having the colors of red (R), green (G), and blue (B), respectively, and turn on the plurality of RGB LEDs (129) at once to generate white light by color mixing. It can also be implemented.

The light guide plate 123 to which light emitted from the plurality of LEDs 129a is incident is spread evenly to a large area of the light guide plate 123 while the light incident from the LED 129 proceeds inside the light guide plate 123 by a plurality of total reflections. The surface light source is provided to the liquid crystal panel 110.

The light guide plate 123 may be formed such that the thickness of the other parts of the light guide plate 123 except for the light incident part is thinner than the light incident part, thereby reducing the thickness of the backlight unit 120 and the overall thickness of the liquid crystal display device.

To this end, the light guide plate 123 may include an inclined surface on an upper surface of the light incident from the LED 129 is emitted.

In addition, the light guide plate 123 may include a pattern having a specific shape on the rear surface to supply a uniform surface light source.

Here, the pattern may be configured in various ways, such as an elliptical pattern, a polygon pattern, a hologram pattern, and the like to guide the light incident into the light guide plate 123. The pattern is formed on the lower surface of the light guide plate 123 by a printing method or an injection method.

The reflector plate 125 is attached to the rear surface of the light guide plate 123 to improve the brightness of the light by reflecting the light passing through the rear surface of the light guide plate 123 toward the liquid crystal panel 110.

At this time, the FPC 140 of the present invention is bent to the rear surface of the backlight unit 120 is formed to cover a portion of the rear surface of the reflecting plate 125 on the light incident portion side.

Therefore, the FPC 140 can prevent the deflection of the reflection plate 125 on the light-receiving portion side, and at the same time, the light guide plate 123 is caused by the gap between the reflection plate 125 and the light guide plate 123. Even if it is exposed to the outside, light leakage and loss of light can be prevented from occurring through the area thereof.

The optical sheet 121 on the light guide plate 123 includes a diffusion sheet and at least one light collecting sheet.

Here, the diffusion sheet is positioned directly above the light guide plate 123, and serves to adjust the direction of light so that the light travels toward the light condensing sheet while dispersing the light incident through the light guide plate 123.

The light diffused through the diffusion sheet by the light collecting sheet is focused in the direction of the liquid crystal panel 110. Therefore, the light passing through the light condensing sheet is almost perpendicular to the liquid crystal panel 110.

The liquid crystal panel 110 and the backlight unit 120 are modularized through the support main 130. The support main 130 has a rectangular frame shape so as to surround edges of the liquid crystal panel 110 and the backlight unit 120. do.

In this case, the support main 130 includes a vertical portion 131 covering the edges of the liquid crystal panel 110 and the backlight unit 120, and the liquid crystal panel 110 and the backlight unit (inside the vertical portion 131). A protrusion 133 is provided to distinguish the position of the 120, and the liquid crystal panel 110 is attached to the protrusion 133 by an adhesive material such as a double-sided tape.

In addition, while the FPC 140 attached to the pad region of the first substrate 112 of the liquid crystal panel 110 is bent and adhered to the back surface of the backlight unit 120, the FPC 140 and the support main 130 are They are attached to each other through adhesive materials such as double-sided tape.

The liquid crystal display according to the embodiment of the present invention has a structure in which the top cover (not shown) and the cover bottom are removed, and the light weight and thinness of the liquid crystal display device are removed by removing the top cover (not shown) and the cover bottom (not shown). This is possible and has the effect of simplifying the process.

In addition, due to the removal of the top cover (not shown) and cover bottom (not shown) made of a metal material, it is possible to reduce the process cost.

Here, the support main 130 may be referred to as a guide panel or a main support, a mold frame.

2 is a rear perspective view schematically showing an FPC according to an embodiment of the present invention.

As shown, the FPC 140 is mounted by a surface mount technology (SMT) with a plurality of LEDs 129 spaced apart at regular intervals, the outer surface of the FPC 140 is mounted on the opposite side A driving element (not shown) for transmitting a signal to a gate and a data driving circuit (115 in FIG. 1) formed in the pad region of the first substrate (112 in FIG. 1) of the liquid crystal panel (110 in FIG. 1) is mounted. Various signals are applied to the liquid crystal panel 110 of FIG. 1 through the driving element (not shown) and the wiring (not shown) formed in the FPC 140.

In addition, the FPC 140 is mounted with an LED driving circuit (not shown) for operating the LED 129 in response to a signal input connected to an external driving circuit unit (not shown).

The FPC 140 includes first and second layers 141a and 141b, and the first layer 141a is a region in which a driving device (not shown) is mounted, and a base film (not shown) and a base film (not shown). A plurality of metal wires (not shown) formed by patterning a conductive material for applying a signal to a driving device (not shown) is formed thereon.

In this case, the base film (not shown) of the first layer 141a may be formed to have an opaque color.

In addition, the second layer 141b is an area in which a plurality of LEDs 129 are mounted, and the second layer 141b also signals a plurality of LEDs 129 on the base film (not shown) and the base film (not shown). It consists of a plurality of metal wires (not shown) for application.

Here, each base film (not shown) serves to mount and support a plurality of metal wirings (not shown), a driving device (not shown), and a plurality of LEDs 129 on the upper layer.

In addition, a cover layer (not shown) is formed on the plurality of metal wires (not shown) of each of the layers 141a and 141b as an organic or inorganic insulating material for protecting the plurality of metal wires (not shown).

The FPC 140 is connected to a control PCB (not shown) and a flexible cable (flexible cable 145, see FIG. 1), which are separately provided on a rear surface of the liquid crystal display device through a connector (not shown) provided at one end thereof. A control signal or the like is applied from a control PCB (not shown) to a driving element (not shown) and an LED driving circuit (not shown) mounted on the FPC 140.

The FPC 140 is bent and adhered to the back of the backlight unit 120 (FIG. 1) so that the LED 129 mounted on the FPC 140 receives the light incident surface of the light guide plate 123 of FIG. 1 (123a in FIG. 1). Face to face.

Through this, the present invention can reduce the process cost, it can bring a thin and light weight of the liquid crystal display device.

That is, in order to position the plurality of LEDs 129 on one side of the light guide plate (123 of FIG. 1), a conventional liquid crystal display device must separately include a PCB (not shown) for mounting the LEDs 129. In the liquid crystal display device of the present invention, the LED 129 is mounted on the FPC 140 attached to the pad region of the first substrate 112 of the liquid crystal panel 110 of FIG. 1, and the FPC 140 is a backlight unit. It is to bend to the back of (120 of FIG. 1).

Accordingly, an expensive PCB (not shown) for mounting the LED 129 may be eliminated, thereby reducing manufacturing costs and simplifying the structure. In addition, by removing the PCB (not shown), the thickness and weight of the liquid crystal display device may be as much as the thickness and weight occupied by the existing PCB (not shown).

At this time, the FPC 140 is positioned so that the second layer 141b on which the LED 129 is mounted is positioned inward, so that the FPC 140 is bent to the rear surface of the backlight unit 120 of FIG. 1 to be in close contact with the FPC 140. It is preferable that the LED 129 mounted on the second layer 141b of 140 face the light incident surface (123a of FIG. 1) of the light guide plate 123 of FIG. 1.

In addition, since the first layer 141a on which the driving device (not shown) is mounted is positioned outward, electrical connection between the control PCB (not shown) and the driving device (not shown) provided on the rear surface of the liquid crystal display device is performed. It is desirable to make the connection easier.

On the other hand, when the LED 129 is mounted on the FPC 140 attached to the liquid crystal panel 110 of FIG. 1, the FPC 140 is connected to the backlight unit 120 of FIG. 1. The FPC 140 of the present invention is bent to be closely attached to the rear surface, and the FPC 140 of the present invention is further provided with a light leakage prevention area 143, and a part of the rear surface of the reflector plate (125 in FIG. 1) on the light incident part side is provided through the light leakage prevention area 143. Cover it.

In this case, the light leakage preventing region 143 of the FPC 140 is formed of only one of the first and second layers 141a and 141b of the FPC 140, thereby preventing the thickness of the liquid crystal display from increasing. Preferably, the light leakage preventing region 143 is formed by extending the first layer 141a on which the driving element (not shown) located on the outside of the FPC 140 is mounted. It is preferable to prevent a step caused by the light leakage preventing region 143 of the 140.

In particular, since the base film (not shown) of the first layer 141a has an opaque color, the light leakage preventing effect may be further improved.

In this case, the light leakage preventing region 143 may be formed by extending only the base film (not shown) of the first layer 141a.

Through this, the light guide plate 123 of FIG. 1 may be prevented from being exposed to the outside, and light leakage and light loss may be prevented from being generated by the light guide plate 123 of FIG. 1. This will be described in more detail with reference to FIG.

FIG. 3 is a schematic cross-sectional view of the modular LCD of FIG. 1.

As illustrated, the liquid crystal panel 110 is disposed between the first and second substrates 112 and 114 and a liquid crystal layer (not shown), and each of the first and second substrates 112 and 114 is positioned. On the outer surface, polarizing plates 119a and 119b for selectively transmitting only specific light are attached.

At this time, as mentioned above, the second substrate 114 is smaller than the first substrate 112 and partially exposes one edge of the first substrate 112, and one edge of the first substrate 112 has a COG method. Thus, the gate and data driver circuit 115 are mounted.

The gate and data driver circuit 115 outputs various signal voltages and is electrically connected to the FPC 140 mounted with a plurality of LEDs 129.

The rear surface of the liquid crystal panel 110 includes an optical sheet 121, a light guide plate 123, a reflective plate 125 attached to a lower portion of the light guide plate 123, and a plurality of LEDs 129 mounted on the FPC 140. It includes a backlight unit 120 is located.

At this time, the FPC 140 is in close contact with the back of the backlight unit 120, the plurality of LEDs 129 mounted on the FPC 140 is the vertical portion 131 and the light guide plate of the support main 130 ( It is positioned between the light incident surface 123a of the 123.

Through this, the plurality of LEDs 129 emit light toward the light incident part L1 of the light guide plate 123.

At this time, the light guide plate 123 is formed in a flat (flat) shape having a predetermined thickness, the inclined surface is formed on the upper surface, the portion where the thickness (d1) of the light incident portion (L1) facing the plurality of LEDs 129 is different It is formed thicker than the thickness d2 of L2.

That is, the light guide plate 123 is configured such that the parallel lower surface and the upper surface corresponding to the lower surface are inclined at the light incidence part L1, so that the thickness d2 of the display portion L2 of the light guide plate 123 is the light incidence part. It forms so that it may become thin compared with the thickness d1 of (L1).

As a result, all of the light emitted from the LED 129 is incident into the light guide plate 123 through the light incidence part L1 of the light guide plate 123, and the thickness d2 of the display part L2 of the light guide plate 123. Can be formed thin.

Therefore, the overall thickness of the backlight unit 120 including the light guide plate 123 and the optical sheet 121 may be formed so as not to exceed the thickness d2 of the light incident part L2 of the light guide plate 123.

The liquid crystal panel 110 and the backlight unit 120 are modularized by the support main 130, and the support main 130 is a vertical portion 131 which surrounds the edge of the backlight unit 120 and the liquid crystal panel 110. The inside of the vertical part 131 is provided with a protrusion 133, and the liquid crystal panel 110 is seated and supported on the protrusion 133. In this case, the liquid crystal panel 110 is attached through the protrusion 133 of the support main 130 and an adhesive material 150 such as a double-sided tape.

In addition, the FPC 140, which is connected to the liquid crystal panel 110, is bent in close contact with the rear surface of the backlight unit 120, and a portion of the inner side of the second layer 141b of the FPC 140 is perpendicular to the support main 130. The back of the portion 131 and the adhesive material 150, such as a double-sided tape is attached.

The FPC 140 is formed such that the light leakage preventing region 143 extending from the first layer 141a covers a portion of the rear surface of the reflector plate 125.

Accordingly, the back surface of the light guide plate 123 may be prevented from being exposed to the outside, and light leakage and light loss may be prevented from occurring by the light guide plate 123 exposed to the outside.

Looking at this in more detail, the reflector 125 is formed to have a smaller size than the light guide plate 123, or due to a process error in the process of attaching the reflector 125 to the back surface of the light guide plate 123 and the reflector 125 and A gap between the light guide plate 123 is generated, thereby exposing a part of the rear surface of the light incident part L1 side of the light guide plate 123.

Light leakage of light incident into the light guide plate 123 is generated through a portion of the rear surface of the light guide plate 123 thus exposed, thereby causing light loss.

In particular, in the structure in which the cover bottom (not shown) covering the rear surface of the backlight unit 120 is removed as in the present invention, the problems caused by such light leakage and light loss are more highlighted.

Accordingly, the present invention further forms the light leakage preventing region 143 in the FPC 140, and the light leakage preventing region 143 surrounds a part of the rear surface of the reflecting plate 125 so that the rear surface of the light guide plate 123 is moved to the outside. Exposure can be prevented, and light leakage and light loss can be prevented from occurring.

In addition, by supporting the rear surface of the reflector 125 through the light leakage preventing region 143 of the FPC 140, it is possible to prevent the deflection of the reflector 125.

As described above, the liquid crystal display of the present invention allows a plurality of LEDs 129 to be mounted on the FPC 140 connecting the liquid crystal panel 110 and a control PCB (not shown), thereby providing a plurality of LEDs 129. The process cost can be reduced by eliminating a separate PCB (not shown) for mounting the board, and the thickness and weight of the liquid crystal display device can be as thin and light as the conventional PCB (not shown) in the liquid crystal display device. have. In addition, the process time for modularizing the liquid crystal display device can be shortened.

In particular, by further forming the light leakage preventing region 143 on the FPC 140, the back surface of the light guide plate 123 through the light leakage preventing region 143 of the FPC 140 is bent and closely contacted to the back of the backlight unit 120. It can be prevented from being exposed to the outside, through which light leakage and light loss can be prevented.

The present invention is not limited to the above embodiments, and various modifications can be made without departing from the spirit of the present invention.
