The LCD panel 10 includes a color filter for outputting red, green and blue, a liquid crystal and a thin film transistor (TFT), and outputs various images by applying a signal to the color filter.

The touch panel 23 includes a transparent electrode pattern (ITO film) made of a translucent material, and a data pattern is formed on the outer surface of the touch panel 23. The touch panel 23 may be in the form of a film or a sheet, and is coupled to the front surface of the LCD panel 10.

In addition, since the touch panel 23 can be manufactured integrally with the front cover glass 21, a transparent electrode pattern and a data pattern of the touch panel 23 are stacked on the direct cover glass 21 .

However, since the data pattern formed on the outer surface of the conventional touch panel 23 is made of opaque material, the opaque window bezel 22 is formed on the window layer to cover the data pattern, .

Further, as shown in Fig. 9, the adhesive tape 25 is required because the cover glass 21 including the touch panel 23 is assembled in the manner of engaging the front surface of the case with the cover glass 21. The adhesive tape 25 must be covered with the opaque window bezel 22 so that the area of the left and right window bezels 22 is increased and the thickness of the mobile terminal is also increased.

In such a conventional mobile terminal, since the width (1) including the size (3) of the case 1 and the size (2) of the window bezel 22 is required on both sides, There is a problem that the size of the portion becomes smaller.

Therefore, in the present invention, an in-cell type touch screen 210 which can omit the data pattern is used to omit the side window bezel.

The touch screen 210 of the in-cell type is formed by laminating a separate touch panel 23 on the LCD panel 10 as shown in FIGS. 6 to 8 by adding a transparent electrode pattern ITO to the LCD panel for image output no need.

The thickness of the touch panel 210 can be reduced by the thickness of the conventional touch panel 23 (see FIG. 9), and the decrease in the contrast ratio caused by the touch panel 23, Reduction of surface reflection and the like can be solved, and the original characteristics of the LCD panel can be maintained.

In particular, since the touch panel 210 of the in-cell type has a touch function on the LCD panel itself, a data pattern formed around the touch panel is unnecessary. That is, the conventional side window bezel 22 for covering the side data pattern becomes unnecessary.

Referring to FIG. 5, the window layer 220 of the present invention includes an intermediate transparent display region 221 and opaque window bezels 223 at the top and bottom. The window layer 220 of the present invention may dispense with the window bezel 22 formed on the left and right sides of the mobile terminal, unlike the conventional window layer 20.

The coupling structure of the mobile terminal 100 of the present invention will be described in more detail with reference to FIG.

The touch screen 210 of the present invention is larger in size than the through-hole 101a formed in the case 101. Since the touch screen 210 is coupled to the through window 101a from the inside of the case 101 as shown in FIG. 6, the right and left ends of the through- .

The window layer 20 coupled to the front surface of the conventional case 1 prevents the window layer 20 from being lifted by using the adhesive tape 25. In the present invention, the adhesive tape 25 is omitted, The upper surface of the screen 210 and the inner surface of the case 101 are held in contact with each other.

In addition, since the touch screen 210 of the present invention uses the insensitive type, there is no opaque data pattern existing around the touch panel. Therefore, the mobile terminal of the present invention does not need to cover the left and right data patterns and the adhesive tape 25, so that the left and right window bezels 22 can be omitted.

However, even in the case of the in-cell type touch screen 210, the area where the actual screen is output (Active Area) is smaller than the size of the entire touch screen 210. Therefore, in order to cover the portion where the screen is not printed, the case 101 may partly cover the entire circumference as shown in Figs.

Therefore, in the present invention, since the bezel length (4) of the entire bezel is required only on the side in addition to the screen output portion, the entire bezel size can be reduced as compared with the conventional mobile terminal.

The window layer 220 is coupled to the front surface of the touch screen 210 and inserted into the through window 101a. That is, the window layer 220 is the same size as the penetration window 101a, and the window layer 220 is substantially located in the same plane as the case 101. Since the window layer 220 is the same size as the penetration window 101a, the left and right sides of the window layer 220 are shorter than the touch screen 210 and longer than the touch screen 210.

The window layer 220 further includes a waterproof loop 243 formed on a sidewall of the through window 101a in contact with the window layer 220 because the window layer 220 is coupled with the perimeter of the through window 101a . The waterproof loop 243 can prevent the window layer 220 from being stably fixed to the case 101 and prevent moisture or foreign matter from penetrating between the window layer 220 and the case 101. [

A window bezel 223 is formed on upper and lower portions of the touch screen 210 to cover the sound module 152 and the camera module 121.

In addition, in order to fix the window layer 220, an adhesive tape conventionally used may be attached to the end portion of the touch screen 210 and the window layer 220 You do not have to. It is advantageous in terms of thickness, and it is also possible to prevent the window bezel from unnecessarily increasing on the side surface.

However, since the upper and lower portions of the window layer 220 are not supported by the touch screen 210, the upper and lower portions of the window layer 220 may be attached to the case 101 or the inner parts Can be fixed.

Since the upper and lower portions include a bezel for the camera module 121, the sound module 152, and the like, there is a margin for attaching the adhesive tape.

The touch screen 210 may further include a back light unit 215 on a rear surface thereof. The rear dimming device 215 emits white light so that the image output from the touch screen 210 reaches the user's eyes. The light output from the rear dimming device 215 passes through the color filter of the touch screen 210 Various colors can be realized.

And may further include a rear dimming device 215 and a screen holder 235 coupled to the side of the touch screen. The screen holder 235 may be configured such that the rear dimming device 215 and the touch screen 210 are not separated so that light emitted from the rear dimmer device 215 is not leaked in a direction other than the touch screen 210 Shielding.

A display unit of a hybrid type in which the window layer 220, the touch screen 210, the rear dimmer device 215, and the screen holder 235 are integrally formed can be used. The display unit of the hybrid type can be fixed to the case 101 only by fixing the left and right ends of the touch screen 210 inside the both sides of the through window 101a of the case 101 when the members are integrally formed.

The frame 250 is disposed on the rear surface of the touch screen 210 so that the touch screen 210 and the rear light control device 215 can be closely contacted with the front through- .

Further, the side surface of the frame 250 is inserted and fixed in the side groove 242 formed in the inner side surface of the case 101. That is, the frame 250 is fastened to the case 101 in a manner of fitting into the side groove 242.

The position of the side groove 242 may be a position where the touch screen 210 can be closely attached to the through window 101a when the side groove 242 is inserted into the side surface of the frame 250. [

7, the side groove 242 may have a shape in which the frame 250 is inserted according to the shape of the frame 250. In addition, as shown in FIG. 8, when the side height of the frame 250 is smaller than the side height of the touch screen 210, Unit 215, it is in contact with the screen holder 235 or the touch screen 210 in part.

The frame 250 is coupled with the case 101 to fix the touch screen 210 firmly to the front of the case 101. As the material of the frame 250, various materials such as a metal material and a reinforced plastic can be used.

The elastic member 241 may be further provided on the inner side of the through-hole 101a where the touch screen 210 is in contact with the case 101 to prevent the touch screen 210 from being damaged by an external impact .

The elastic portion 241 may be formed entirely along the perimeter of the through window 101a or may be partially formed only on the left and right sides of the through window 101a in contact with the touch screen 210. [
