Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.

First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface or an object existing in the vicinity of the detection surface without mechanical contact using an electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in the inner area of the mobile terminal or in proximity to the touch screen, which is covered by the touch screen. The proximity sensor 141 has a longer life than the contact type sensor and its utilization is also high.

Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Furthermore, the control unit 180 can control the mobile terminal 100 such that different operations or data (or information) are processed according to whether the touch to the same point on the touch screen is a proximity touch or a touch touch .

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch object to be touched on the touch screen on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.

Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Thus, the control unit 180 can know which area of the display unit 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.

On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object, which touches the touch screen (or a touch key provided on the touch screen). Whether to perform different controls or to perform the same control according to the type of the touch object may be determined according to the current state of the mobile terminal 100 or an application program being executed.

Touch can be sensed.

The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

The camera 121 includes at least one of a camera 121, a photosensor, and a laser sensor. The camera 121 is a kind of camera sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

For example, the liquid crystal panel 151a may be deformed into a curved shape by attaching to the curved window 151 ", while maintaining the flat shape of the liquid crystal panel 151a. The unit 151b may have a preset radius of curvature.

The window 151 "is disposed to cover the liquid crystal panel 151a and is made of a material (for example, a light transmitting synthetic resin, a tempered glass, or the like) capable of transmitting light so that an image displayed on the liquid crystal panel 151a can be transmitted The window 151 " may be formed to be curved along one direction. For example, the window 151 "may be formed to be curved along the longitudinal direction L of the terminal body, and may have a preset radius of curvature.

As shown, the flat liquid crystal panel 151a is attached to the rear surface of the window 151 ". By the above attachment, the liquid crystal panel 151a is deformed in a bent shape corresponding to the shape of the window 151 " At this time, the liquid crystal panel 151a may have a preset radius of curvature.

This has the advantage that a curved display can be manufactured at a lower cost as compared with the case of implementing a curved display with an organic light-emitting diode (OLED).

On the other hand, the curved shape of the liquid crystal panel 151a and the backlight unit 151b is not limited to that described above. Various methods can be applied to the curved shape implementation.

Referring to Figs. 6 and 7, frames 101 and 104 include a base frame 101 and a middle frame 104. Fig. The frames 101 and 104 may be made of different combinations of materials. For example, the base frame 101 may be formed of a synthetic resin material, and the middle frame 104 may be formed of a metal material.

The base frame 101 is coupled to the window 151 ". At least a part of the base frame 101 may be exposed to the outside to form a lateral appearance of the terminal body.

The base frame 101 may include a back support portion 101a and a side cover portion 101b.

The back support 101a supports the back surface of the window 151 ". The back support 101a may form a loop corresponding to the edge area to support the back edge area of the window 151 ".

The side cover portion 101b is disposed to cover the side surface of the window 151 ". The side cover portion 101b may protrude to be flush with the top of the window 151 ". According to the above structure, when the mobile terminal 100 is viewed from the front, the step between the window 151 '' and the frames 101 and 104 is not exposed, so that the appearance of the mobile terminal 100 can be realized more cleanly.

For example, the base frame 101 and the middle frame 104 may form frames 101 and 104 integrally formed by injection molding.

The middle frame 104 is coupled with a backlight unit 151b. The middle frame 104 to which the backlight unit 151b is attached is formed to be curved along one direction. 6 illustrates that the backlight unit 151b, which is manufactured in a flat shape, is deformed into a bent shape by receiving a bending force due to the bent shape of the middle frame 104 when the backlight unit 151b is mounted on the middle frame 104. [

However, the backlight unit 151b does not necessarily have a shape bent by this coupling structure. The backlight unit 151b may be bent in the one direction or may be bent in the one direction before being attached to the middle frame 104 so as to be mounted on the middle frame 104. [

According to the structure in which the reflectors are provided inside the frames 101 and 104, the white mold provided in the conventional backlight unit 151b is removed, so that the space between the side surfaces of the frames 101 and 104 and the backlight unit 151b The spacing can be reduced. As a result, the bezel can be shrunk, and the mobile terminal 100, which can be configured with a large area and a large area, can be provided.

On the other hand, the window 151 "with the liquid crystal panel 151a is coupled to the frames 101, 104 to which the backlight unit 151b is attached. When the window 151" is coupled to the frames 101, 104 The backlight unit 151b is disposed on the back surface of the liquid crystal panel 151a. At this time, a gap may be formed between the liquid crystal panel 151a and the backlight unit 151b.

The light shielding member 151c is formed in a loop shape extending along the upper edge of the backlight unit 151b to separate the inner space between the liquid crystal panel 151a and the backlight unit 151b from the outer space.

In this figure, it is exemplified that the light shielding member 151c is disposed so as to cover the upper edge of the backlight unit 151b and the reflecting member 134. [ It is preferable that the reflecting member 134 is protruded to be flush with the top of the backlight unit 151b so that the light shielding member 151c can be stably stably mounted on the backlight unit 151b and the reflecting member 134. [

The light shielding member 151c may be in close contact with the liquid crystal panel 151a and the backlight unit 151b to prevent foreign matter from penetrating between the liquid crystal panel 151a and the backlight unit 151b. It is preferable that the light shielding member 151c is formed of a predetermined elastically deformable material (for example, silicone, rubber or the like). In order to prevent the liquid crystal panel 151a from being stained due to the pressing and to prevent the liquid crystal panel 151a and the backlight unit 151b from being broken during the close contact, the light shielding member 151c is provided with a liquid crystal panel 151a, Unit 151b, and the thickness thereof must be determined in consideration of the degree of elastic deformation of the light-shielding member 151c.

The light shielding member 151c which is in close contact with the liquid crystal panel 151a and the backlight unit 151b prevents leakage of the light generated in the backlight unit 151b as well as the liquid crystal panel 151a and the backlight unit 151b. Foreign matter penetration into the space 151b can also be prevented.

8 is a plan view of the frames 101 and 104 shown in Fig.

Only the flat liquid crystal panel 151a is attached to the curved window 151 "as described above. According to the above structure, the flat liquid crystal panel 151a and the backlight unit 151b are attached to the curved window 151" The force received by the window 151 "(i.e., the force for deforming the window 151" into a flat shape) is reduced.

Accordingly, the window 151 "can maintain the bent state without large deformation, and can stably be coupled to the bent shaped frames 101 and 104. According to the structure, the configuration of the bonding portion 133 The bonding section 133 will be described below.

Referring to FIG. 8, the bonding portion 133 may be disposed on the back surface support portion 101a of the base frame 101. FIG. Both sides of the back surface support portion 101a corresponding to the width direction W of the main body of the terminal are formed to be thin and long compared with both ends of the back surface support portion 101a corresponding to the longitudinal direction L of the terminal main body.

On the other hand, in order to apply the bonding layer to the backside support portion 101a, a minimum area for controlling the flow of the liquid phase is required. However, the areas on both sides of the backside support 101a correspond to a considerably small area for applying the bonding layer. This is more so when considering the trend of the current mobile terminal 100 where the side bezel is decreasing.

The bonding portion 133 may be formed by a combination of an adhesive tape 133a provided on both sides of the backside support portion 101a and a bonding layer 133b provided on both ends of the backside support portion 101a. Since the bonding force of the bonding layer 133b is greater than the bonding force of the adhesive tape 133a, the bonding between the window 151 '' and the base frame 101 is mainly performed by the bonding layer 133b, And may be made to assist the coupling.

As shown in the figure, the adhesive tape 133a may extend from one end of the back support 101a toward the other end.

9 is an enlarged view of a portion B shown in Fig.

The display 151 'may have a mutual layer structure with the touch sensor or may be integrally formed to realize a touch screen. Such a touch screen may provide an input interface between the mobile terminal 100 and a user while providing an output interface between the mobile terminal 100 and the user.

In this drawing, a touch sensor is formed or attached to the rear surface of the window 151 ", and a flexible circuit board 182 electrically connected to the touch sensor is disposed at one end of the window 151 ".

A hole 101d through which the flexible circuit board 182 penetrates is formed in the base frame 101, specifically, the back surface support portion 101a. The flexible circuit board 182 may be electrically connected to a circuit board (not shown) disposed on the rear surface of the middle frame 104 through the hole 101d.

As described above, the rear supporting portion 101a is provided with a bonding portion 133 for coupling the window 151 "to the frames 101, 104. When the window 151" is seated on the rear supporting portion 101a The hole 101d is formed in a position corresponding to the flexible circuit board 182 so that the flexible circuit board 182 can pass through the hole 101d without bending. According to the above structure, the area of the bonding portion 133 on the backside support portion 101a can be increased.

10 is an exploded view showing another example of the mobile terminal 200 according to the present invention.

Referring to Fig. 10, a flat liquid crystal panel 251a is attached to the back surface of the window 251 ", and is formed in a shape bent corresponding to the window 251 ". At this time, the liquid crystal panel 251a receives a bending force due to the bent shape of the window 251 ".

On the other hand, the backlight unit 251b has a shape that is warped to some extent in accordance with the curved shape of the frames 201 and 204 before attaching to the frames 201 and 204. [ For example, the backlight unit 251b may be bent in one direction, or may be bent in one direction before attachment to the frames 201 and 204 through equipment (JIG) or manual operation.

The backlight unit 251b may bend or be bent to correspond to the bent frames 201 and 204. [ As such, the bent backlight unit 251b is attached to the bent frames 201 and 204. [

In a state in which the backlight unit 251b is coupled to the frames 201 and 204, the degree of warping of the backlight unit 251b is substantially the same as in the previous embodiment. Since the backlight unit 251b has already been bent before attaching the frames 201 and 204 to the backlight unit 251b due to the bending force and bending of the backlight unit 251b due to the bent shape of the frames 201 and 204 251b decreases in comparison with the previous embodiment. According to such a coupling structure, the area of the adhesive member for coupling the backlight unit 251b to the frames 201 and 204 can be reduced.

However, it is difficult to apply the bonding layer 333 to the side cover portion 301b having a thin thickness, and the bonding layer 333 applied to the side cover portion 301b when the window 351 " 333 may flow out to the outside.

In order to prevent this, an inclined guide portion 301c is formed between the backside support portion 301a and the side cover portion 301b, and the bonding layer 333 can be applied only to the backside support portion 301a. The bonding layer 333 applied to the backside support portion 301a is introduced into the side cover portion 301b by the inclined guide portion 301c when the window 351 "is engaged with the base frame 301 As a result, the bonding layer 333 is applied to both the back surface support portion 301a and the side surface cover portion 301b so that the adhesion between the window 351 " and the base frame 301 can be enhanced by increasing the bonding area have.
