[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] See also Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a water drop screen integrated touch display module structure 10 includes: a cover plate 100, a liquid crystal display screen 200 and a backlight module 300, the cover plate 100, the liquid crystal display screen 200 and the backlight module 300 are stacked in sequence; the backlight module 300 includes a backlight support frame, and a backlight gap 310 is formed on the backlight support frame, and the backlight gap 310 is used to place the camera module 20; the backlight support frame includes a backlight glue frame 320 and a backlight iron frame 330, the backlight gap 310 is formed on the backlight iron frame 330, and the backlight iron frame 330 is provided with a bent and inclined portion 331 around the periphery of the backlight gap 310, and the free end of the bent and inclined portion 331 extends obliquely toward the direction close to the center of the backlight gap 310 to increase the space of the backlight gap 310, and the backlight glue frame 320 is arranged on the backlight iron frame 330, and the backlight glue frame 320 is arranged around the backlight gap 310.

[0025] It should be noted that a backlight gap 310 is provided on the backlight support frame so that the camera module 20 can be installed in the backlight gap 310. At the same time, a bending and tilting portion 331 is provided around the periphery of the backlight gap 310 of the backlight iron frame 330. The free end of the bending and tilting portion 331 extends obliquely toward the center of the backlight gap 310, so that the inner side wall of the backlight gap forms a chamfered structure. While ensuring that the screen-to-body ratio remains unchanged, the space of the backlight gap 310 is increased. In this way, the external structure of the camera module can also be increased accordingly, thereby improving the product performance of the camera module. At the same time, the processing difficulty of a larger camera module is lower than that of a smaller camera module, so the corresponding cost is also lower. In addition, by providing a backlight rubber frame 320, it plays a role in preventing light leakage, that is, the light source of the backlight module is blocked by the backlight rubber frame 320 to prevent light leakage from affecting the use of the camera module 20.

[0026] Preferably, the backlight iron frame 330 is provided with a bending and tilting portion 331 around the backlight notch 310, and the bending and tilting portion 331 is located on a side close to the center of the backlight module 300. That is, the bending and tilting portion 331 is located at the lower end of the backlight notch 310, which can be seen in FIG. Figure 2 and Figure 3 As shown, the space of the backlight gap 310 is enlarged by bending the inclined portion 331, thereby making the structure of the camera module larger.

[0027] Furthermore, a rubber frame inclined surface 321 is provided in the area of ​​the backlight rubber frame 320 corresponding to the bent inclined portion 331, and the side of the bent inclined portion 331 facing the backlight notch 310 is an iron frame inclined surface, and the iron frame inclined surface and the rubber frame inclined surface 321 are located on the same inclined plane. That is, by providing the rubber frame inclined surface 321 and cooperating with the iron frame inclined surface, the positions of the backlight rubber frame and the backlight iron frame corresponding to the backlight notch are chamfered, so that the space of the backlight notch 310 can be further increased while ensuring that the screen-to-body ratio remains unchanged. In addition, the longer the size of the bent inclined portion 331, the shorter the size of the corresponding rubber frame inclined surface 321. It depends on the actual design. While ensuring that the bent inclined portion 331 has sufficient support area for the rubber frame inclined surface 321, the area of ​​the rubber frame inclined surface should be as large as possible, so as to reduce the camera module and the metal bent inclined portion 331 from being scratched and damaged.

[0028] Preferably, the backlight iron frame 330 and the backlight plastic frame 320 are an integrated iron and plastic structure, that is, a corresponding mold is used so that the backlight iron frame and the backlight plastic frame can be formed into one piece to improve processing efficiency and ensure the strength of the backlight iron frame and the backlight plastic frame.

[0029] Preferably, the cover plate 100 is a glass cover plate.

[0030] Preferably, the cover plate 100 is connected to the liquid crystal display screen 200 through an optical adhesive 400. For example, the optical adhesive 400 may be an OCA (special adhesive) optical adhesive.

[0031] Furthermore, the liquid crystal display screen 200 includes an upper polarizer 210 , an upper glass 220 , a lower glass 230 and a lower polarizer 240 stacked in sequence. The upper polarizer 210 is located on a side close to the cover plate 100 , and the lower polarizer 240 is located on a side close to the backlight module 300 .

[0032] Furthermore, the backlight module 300 also includes an optical element. A receiving cavity is provided on the backlight support frame, and the optical element is received in the receiving cavity. The display effect of the display module is improved by the optical element. Specifically, the optical element includes an upper light-enhancing film 510, a lower light-enhancing film 520, a diffusion film 530, a light guide plate 540 and a reflective film 550 stacked in sequence, and the upper light-enhancing film 510 is located on a side close to the liquid crystal display screen 200.

[0033] Furthermore, the backlight module 300 further includes a light shielding glue 340, which is located between the backlight support frame and the liquid crystal display screen. The light shielding glue plays a role in preventing light from leaking out, for example, the light shielding glue is a dark light shielding glue such as black or gray.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
