[0021] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.

[0022] Please refer to Figures 1 to 3 , a touch display screen module 10, comprising: a cover plate 100, an upper polarizer 200 and a backlight module 300. The cover plate 100 includes a visible area 110 and a non-visible area 120, and a light-shielding layer 121 is provided on the non-visible area 120. One side of the upper polarizer 200 is connected to the cover plate 100. The upper polarizer 200 includes a button portion 210, and a sensor function layer 211 is provided on the side of the button portion 210 close to the cover plate 100. A solar charging layer 220 is provided on the side of the upper polarizer 200 away from the cover plate 100. The backlight module 300 is connected to the other side of the upper polarizer 200. A receiving groove 310 is formed on the backlight module 300, and a display screen 400 and a lower polarizer 500 are provided on the receiving groove 310. One side of the display screen 400 is connected to the upper polarizer 200, and the other side of the display screen 400 is connected to the lower polarizer 500. The display area of the display screen 400 is disposed opposite to the visible area 110.

[0023] It should be noted that by providing the solar charging layer 220 on the side of the upper polarizer 200 away from the cover plate 100, the touch display screen module 10 can realize the self-charging function, improving the battery life of the touch display screen module 10 when used outdoors. The solar charging layer 220 needs to avoid the positions of the button portion 210 and the visible area 110 to prevent the functions of the button portion 210 and the clarity of the visible area 110 from being affected. The light-shielding layer 121 provided on the non-visible area 120 adopts the method of screen-printing black ink to block the bright lines at the edge of the solar charging layer 220, beautifying the appearance of the touch display screen module 10. At this time, the light-shielding layer 121 does not completely block the solar charging layer 220 and will not affect the self-charging function of the touch display screen module 10.

[0024] Please refer to again Figure 1 , in one embodiment, the button portion 210 is screen-printed with black semi-transparent ink. Thus configured, the light source of the backlight module 300 can light up the button portion 210, enabling the button portion 210 to display a color.

[0025] Please refer to again Figure 1 and Figure 3 , in one embodiment, an electrochromic layer is provided on the side of the button portion 210 away from the cover plate 100, such that when the button portion 210 is lit, it can present different colors, improving the appearance of the touch display screen module 10, thereby enhancing the market competitiveness of the touch display screen module 10.

[0026] Please refer to again Figure 1, In one embodiment, it further includes a first FPC 600. The first FPC 600 is disposed on the upper polarizer 200 and is electrically connected to the sensor functional layer 211, the electrochromic layer, and the solar charging layer 220 respectively. With this arrangement, the number of FPCs used is reduced, making the structure of the touch display module 10 more compact.

[0027] Please refer to again Figure 1 and Figure 3 , In one embodiment, it further includes a second FPC 700. The second FPC 700 is disposed on the backlight module 300, enabling the backlight module 300 to be connected to other components through the second FPC 700, ensuring that the backlight module 300 can adjust its brightness according to instructions.

[0028] Please refer to again Figure 1 and Figure 3 , In one embodiment, it further includes a third FPC 800. The third FPC 800 is disposed on the display screen 400, enabling the display screen 400 to be connected to other components through the third FPC 800, ensuring that the display screen 400 can display images and information normally according to instructions.

[0029] Please refer to again Figure 3 , In one embodiment, a first adhesive layer 230 is provided between the cover plate 100 and the upper polarizer 200. With this arrangement, the connection between the cover plate 100 and the upper polarizer 200 can be made more stable, preventing the cover plate 100 and the upper polarizer 200 from falling off.

[0030] Please refer to again Figure 3 , In one embodiment, a second adhesive layer 240 is provided between the display screen 400 and the upper polarizer 200. With this arrangement, the connection between the display screen 400 and the upper polarizer 200 can be made more stable, preventing the display screen 400 and the upper polarizer 200 from falling off.

[0031] Please refer to again Figure 3 , In one embodiment, the first adhesive layer 230 and the second adhesive layer 240 are OCA optical adhesive layers. The OCA optical adhesive has good light transmittance and will not affect the clarity of the display on the display screen 400 while connecting the cover plate 100, the upper polarizer 200, and the display screen 400.

[0032] Please refer to again Figure 3 , In one embodiment, a third adhesive layer 250 is provided between the backlight module 300 and the upper polarizer 200. The third adhesive layer 250 preferably uses white glue, which has good high-temperature resistance and chemical resistance, making the connection between the backlight module 300 and the upper polarizer 200 more stable and improving the service life of the touch display module 10.

[0033] The embodiments described above merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
