Further, in the above-mentioned display assembly, the liquid crystal display module may be composed of a rear end and a front end; wherein the rear end is arranged below the touch screen where the button logo is set, and the front end is arranged in front of the rear end and below the touch screen. The rear end of the liquid crystal display module can be a structure made of non-liquid crystal display materials. The front end can use LCD module.

In the display component of this embodiment, each component is specifically implemented as:

a. The touch screen can use a TP module composed of a transparent protective screen (TP CG, Touch panel cover glass) and a touch sensor (TP Sensor, Touch panel Sensor). The button logo (ICON) on the touch screen ) can be realized by screen printing on the transparent protective screen, and the touch sensor (TP Sensor) can be realized by forming an ITO film (Indium Tin Oxides, nano-indium tin metal oxide semiconductor transparent conductive film) on the transparent protective screen (TP CG) ;

b. The light guide component (such as light guide film) can be attached to the touch sensor (TPSensor) of the touch screen (such as TP module) through a jig;

c. The liquid crystal display module (LCD module) can be attached to the touch sensor (TPSensor) of the touch screen through optical glue (OCA);

d. The light-emitting component (set on one side of the light-guiding component, which is a side-emitting LED light) can illuminate the button logo (ICON) on the touch screen (such as the TP module) through the light-guiding component (such as a light-guiding film).

The display assembly can independently provide backlight for the key logo 1 displayed on the touch screen through the cooperation of the light-emitting part and the light-guiding part, and does not require the liquid crystal display module 5 to provide backlight for the key logo. The liquid crystal display module 5 is composed of the rear end 52 and The front end 51 is formed, and the rear end 52 of the liquid crystal display module 5 is formed below the key mark 1, while the other front ends 51 are used as display screens, and the rear end can be made of non-liquid crystal display materials, so that the front end of the liquid crystal display module 5 is not occupied. The actual use of the area, and easier to control because of the independent backlight provided for the key logo. Since the display component does not increase the volume, it is particularly suitable for use in thin and light terminal devices (mobile phones, tablet computers, etc.) that can be operated by unlocking the screen.

Example 2

This embodiment provides a terminal, which can be a mobile terminal such as a mobile phone, a palmtop computer, and a tablet computer. As shown in FIG. The display component adopts the display component given in Embodiment 1 above.

In the terminal of this embodiment, since the key identification of the display component in the display device is provided with a backlight by the light guide component and the light emitting component alone, there is no need for the liquid crystal display module to provide a backlight, and the premise of not increasing the volume of the display component is realized. (It also ensures that the volume of the terminal is not increased), does not occupy the actual use area of the front end of the liquid crystal display module, and because the light guide part and the light emitting part can be controlled separately, it reduces the difficulty of realizing the backlight control of the button logo.

To sum up, when the display component of the embodiment of the present invention is used in a terminal device, it can be implemented as a touch screen alone without increasing the design space of the terminal and without occupying the actual display area of the liquid crystal display module of the display component. The upper button identification area provides a backlight, and the adjustment of the backlight can be realized by conveniently controlling the light-emitting components through the software.
