However, the display unit including the color filter layer (CF), the liquid crystal layer and the TFT layer is connected to the flexible circuit board (fpcb) for electrical connection with the main circuit board. The flexible circuit board fpcb connected to one end of the TFT layer of the display unit is connected to the main circuit board in a bent state. When one region of the TFT layer is bent by the bending tension of the bent flexible circuit substrate fpcb, the liquid crystal layer is widened. .

As a result, the cell-gap where the liquid crystal layer is formed is increased, and the light transmittance of the green light and the blow light is relatively decreased. As a result, a yellowing phenomenon occurs in which the transmittance of the yellow light is increased.

Accordingly, it is an object of the present invention to provide a mobile terminal having a display unit for preventing yellowing.

According to an aspect of the present invention, there is provided a watch-type terminal comprising: a main circuit board for forming a control signal, a TFT layer, a color filter layer, a liquid crystal layer and a backlight unit, And a flexible circuit board connected to one end of the TFT layer and electrically connecting the display panel and the main circuit board, wherein the display panel includes a TFT layer, a color filter layer, a liquid crystal layer, and a backlight unit And a support portion extending from the mold portion and supporting one end of the TFT layer so as to prevent movement of one end of the TFT layer,

In one embodiment of the present invention, the supporting portion may include first and second supporting members, which contact the side surfaces of the TFT layer and prevent movement of one end of the TFT layer.

As an example related to the present invention, the support portion may include an insertion groove recessed to insert one region of the TFT layer.

According to the present invention, since the one end of the TFT layer can not be moved by the support, it is possible to prevent the TFT layer from being deformed by the elastic force of the flexible circuit board. Therefore, it is possible to prevent the fluctuation of the thickness of the liquid crystal layer and the yellowing phenomenon due to the deformation of the TFT layer.

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 the presence of an object in the vicinity of the detection surface, without mechanical contact by using 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.

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 senses a touch (or touch input) applied to the touch screen (or the display unit 151) by using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, do.

The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched 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 touching 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 sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The camera 121 and the laser sensor may be combined with each other to sense a touch of the sensing object with respect to the three-dimensional stereoscopic image. 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.

3A is a conceptual view showing a structure in which a flexible circuit board 180b is connected to a display panel 300 and FIG. 3B is an enlarged view for explaining a support 410 for supporting the thin film transistor layer 310. FIG.

The display panel 300 includes a thin film transistor (hereinafter referred to as a TFT layer) 310, a color filter layer 320, and a backlight unit 330. A liquid crystal layer (not shown) is formed between the TFT layer 310 and the color filter layer 320. The liquid crystal layer (not shown) is made of a liquid crystal moving by a voltage. The color filter layer 320 includes a red (R) color filter and the backlight unit 330 emits light toward the TFT layer 310 so that the liquid crystal layer (not shown) and the color filter layer 320 to form an image. The liquid crystal layer (not shown) and the color filter layer 320 are disposed on the upper surface of the TFT layer 310 and the backlight unit 330 is disposed on the lower surface of the color filter layer 320.

And a connection part 311 protruding from one end of the TFT layer 310 and electrically connected to the flexible circuit board 180b. The connection portion 311 may be formed in the central region of the end of the TFT layer 301. The flexible circuit board 180b is disposed on the upper surface of the TFT layer 310.

The molding part 400 surrounds one side of the side of the display panel 300, that is, a direction in which the backlight unit 330, the color filter layer 320, and the TFT layer 310 are stacked, As shown in FIG. The display panel 300 is integrally formed with the molding part 400 and may be made of the same material, but is not limited thereto. The molding part 400 is formed with a first thickness d1 in the stacking direction.

However, the side of the TFT layer 310 on which the connection part 311 protrudes is not wrapped in the molding part 400. The supporting part 410 formed from the molding part 400 is arranged to overlap the remaining side surface 312 of the TFT layer 310 which is not overlapped with the flexible circuit board 180b.

The support part 410 may be integrally formed with the molding part 400, but is not limited thereto. The thickness of the support portion 410 in the stacking direction is a second thickness d2 that is wider than the first thickness d1. The supporting part 410 and the molding part 400 are formed on one surface and the supporting part 410 protrudes from the molding part 400 in the direction of the top surface of the TFT layer 310.

The supporting part 410 includes first and second supporting members 410a and 410b formed adjacent to both edges of the molding part 400 while forming a spacing space 411 corresponding to the connecting part 311 do. Preferably, the first and second support members 410a and 410b are formed in contact with the remaining side surface 312.

4A and 4B are conceptual diagrams for explaining a TFT layer in which bending is prevented by the support portion of the present invention.

The display panel 300 includes the TFT layer 310, the color filter layer 320, the backlight unit 330, and the OCR layer 360. The OCR layer 360 adheres the substrate including the color filter layer 320 to the window 151a and serves to fill the space. Accordingly, the display panel 300 may be formed integrally with the window 151a.

4A illustrates a case where the flexible circuit board 180b connected to one end of the TFT layer 310 is disposed in a plane. FIG. 4B illustrates a flexible circuit board 180b connected to one end of the TFT layer 310. FIG. And the curved surface is bent.

When the flexible circuit board 180b is kept flat, no force is applied to the TFT layer 310. When the flexible circuit board 180b forms a curved surface to be connected to the main circuit board 180a, an external force is applied to the TFT layer 310 connected to the end of the flexible circuit board 180b. The flexible circuit board 180b is connected to the TFT layer 310 and the main circuit board 180a at each end thereof and tries to return to the planar state by its own elastic force. As a result, the flexible substrate 180b is subjected to the force F to be bent by the elastic force of the flexible substrate 180b, which is connected to the flexible circuit board 180b. The force to be bent is separated from the backlight unit 330 and applied in a direction to move to the window 151a. A gap G is formed between one side of the TFT layer 310 and the color filter 320 when the end of the TFT layer 310 receives a force to move.

The support portion 410 supports the side surface of the flexible circuit board 180b to limit the movement of the side surface 180b. Thus, it is possible to prevent a yellowing phenomenon that may occur due to the gap (G).

According to this embodiment, movement of one end of the TFT layer connected to the flexible circuit board can be prevented by the support portion extending from the molding portion forming the outer appearance of the display panel. As a result, deformation of one region of the TFT layer is prevented, so that yellowing can be prevented.

The shock absorbing member 430 may be formed to contact the side surface 312 of the TFT layer 310 and may be pressed by the TFT layer 310 as a material deformable by an external force.

Accordingly, it is possible to prevent the TFT layer 310 from being deformed due to a shape error of the TFT layer 310 and the first and second supporting members 410a and 410b. It is also possible to prevent the possibility that the movement of the TFT layer 310 can not be prevented by separating the side surface 312 of the TFT layer 310 from the supporting portion 410.

The impact mitigating member 430 may be attached to the support unit 410, but not limited thereto, and may be fixed to the molding unit 400.

Each of the first and second support members 420a and 420b includes an insertion groove 421a into which one region of the TFT layer 310 is inserted. And the end of the TFT layer 310 is inserted into the insertion groove 421a.

Accordingly, even if the connection part 311 of the TFT layer 310 receives a force in a specific direction by the flexible circuit board 180b because the one end of the TFT layer 310 is inserted, The problem of moving or bending can be prevented.

5C is a conceptual view for explaining a protrusion formed from the support portion according to another embodiment.

The width of the protrusion 422 is preferably narrower than the width of the extension 311 so as not to interfere with the bending of the flexible circuit board.

The protruding portion 422 is formed to be narrower than the supporting portion 420 and overlapped with one region of the flexible circuit board 180b and the extending portion 311. [

Although the protrusion 422 is shown in the form of a plate in the drawing, it is not limited thereto.
