[0035] Embodiment 1

[0036] like Figure 1-Figure 3 As shown, the light-homogenizing film structure provided by the utility model includes: a protective film main body 1, an extension film 2 is fixedly connected to one side of the protective film main body 1, and a light-homogenizing portion is fixedly connected to the extension film 2, the extension film 2 is bendable, and the light-homogenizing portion can be attached after the extension film 2 is bent. The application arranges the extension film 2 on the protective film main body 1 and arranges the light-homogenizing film main body 3 on the extension film 2, so that the light-homogenizing film main body 3 can be connected to the protective film main body 1 through the extension film 2, making the attachment of the light-homogenizing film main body 3 more convenient, thereby improving the production efficiency and production yield.

[0040] Further, such as Figure 1-Figure 3 As shown, the light-distributing part is a light-distributing film body 3, which is fixedly connected to the extension film 2. The light-distributing film is a thin film used to improve display brightness and uniformity. It can evenly distribute the light emitted by the light source to the liquid crystal display panel, thereby improving the display brightness and contrast.

[0041] Further, such as Figure 2 As shown, a half-punching line 201 is provided between the extension film 2 and the protective film body 1, and the half-punching line 201 is used to assist the bending of the extension film 2, and the setting of the half-punching line 201 facilitates the separation of the half-punching line 201 from the protective film body 1, so that after the homogenizing film body 3 is attached, it is more convenient to tear off the protective film body 1.

[0042] Further, such as Figure 2 As shown, the extension film 2 is further provided with a through hole 202, which is located between the light homogenizing film body 3 and the protective film body 1, and is used to assist the bending of the extension film 2.

[0044] Embodiment 3

[0045] like Figure 4-Figure 5 As shown, the touch module provided by the utility model uses a light-distributing film structure, including a cover body 401, a photosensitive hole body 409 is opened on the cover body 401, a protective film body 1 is pasted on the cover body 401, and an extended film 2 is bent around the side of the cover body 401 to achieve the covering of the photosensitive hole body 409 by the light-distributing film body 3, so that when the extended film 2 is bent, the light-distributing film body 3 can cover the photosensitive hole body 409 to meet the usage requirements.

[0046] Further, such as Figure 4 As shown, the light-distributing film body 3 is connected to a side of the cover body 401 away from the protective film body 1 , and the light-distributing film body 3 covers the photosensitive hole body 409 through the connection between the light-distributing film body 3 and the cover body 401 .

[0047] Further, such as Figure 5 As shown, the cover body 401 is also provided with an emitting hole 410 located on one side of the light-sensing hole body 409. The emitting hole 410 is mainly used to transmit signals so as to communicate with external devices. The cover body 401 is also provided with a camera hole 408. The camera hole 408 is used to allow a camera to shoot through the hole so as to realize functions such as video calls and selfies. The size and position of the camera hole 408 need to be determined according to specific application needs and design requirements. The camera hole 408 can also improve the overall aesthetics and user experience of the product.

[0048] like Figure 4 As shown, the touch module of the utility model is further provided with a display part on the side of the cover body 401 away from the protective film body 1, and the side of the display part away from the cover body 401 is connected to the backlight module 407. The cover body 401 can protect the display part from damage. If the display part is exposed to the outside, it is easy to be affected by wear and scratches by sharp objects, which may affect its use effect and lifespan. Therefore, the set cover body 401 can effectively protect the display part from such damage.

[0049] Further, such as Figure 4 As shown, the display part includes an optical glue 402 fixedly connected to a side of the cover body 401 away from the protective film body 1, and the side of the optical glue 402 away from the cover body 401 is fixedly connected to an upper polarizer 403, and the optical glue 402 is used to connect the cover body 401 and the upper polarizer 403 together, and the side of the upper polarizer 403 away from the optical glue 402 is fixedly connected to an upper glass 404, and the upper glass 404 can play the role of anti-scratch, anti-wear, anti-fingerprint, etc., to improve the durability and use experience of the touch module, and the upper glass 404 can also be used as a part of the touch module to realize the touch function; the upper polarizer 403 can improve the display effect. Since the liquid crystal display panel itself does not emit light, the backlight module 407 is required to provide a light source to display the image. However, the light source of the backlight module 407 is not completely uniformly irradiated, so problems such as uneven brightness and color deviation may occur, and through the optical effect of the upper polarizer 403, the light source of the backlight module 407 can be further adjusted and optimized to improve the display effect.

[0050] Further, such as Figure 4As shown, the display unit also includes a lower glass 405 fixedly connected to a side of the upper glass 404 away from the upper polarizer 403, a side of the lower glass 405 away from the upper glass 404 is fixedly connected to a lower polarizer 406, and a side of the lower polarizer 406 away from the lower glass 405 is fixedly connected to a backlight module 407. The backlight module 407 mainly provides sufficient light source for the touch module so that it can display images normally. Since the liquid crystal itself does not emit light, the backlight module 407 is required to provide a light source to ensure that the image can be displayed clearly and brightly. The backlight module 407 is usually composed of LED lights or other light sources, thereby improving display quality and contrast;

[0051] The lower glass 405, as the substrate of the touch screen, can provide a stable physical environment for the touch module, ensuring the normal operation of the touch module under various environmental conditions;

[0052] The function of the lower polarizer 406 is mainly to adjust and optimize the display light to improve the display effect and contrast. Specifically, the lower polarizer 406 can polarize the light through its own optical effect, so that the light can better pass through the lower polarizer 406 and enter the human eye, thereby making the displayed image clearer and brighter.
