Problems solved by technology

[0005] First, traditionally, the camera and the display cannot be overlapped, because the display will block light from entering the camera, and the camera has a certain volume. When the camera and the display are staggered, the camera occupies a certain space, resulting The area where the camera is located cannot provide display, which is also an important reason why there are relatively large black borders on conventional mobile phones;
[0006] Second, there are existing through-holes in the display module that can block the light from entering, that is, the display screen is also provi

Embodiment 1

[0042] The bonding process includes the following process steps:

[0043] a. First cut the upper polarizer 30, the lower polarizer 50 and the backlight plate 60 into a size consistent with the shape of the display area 41 of the display screen 40, and remove any pixel grid in the display area 41 on the display screen 40 A non-display area 4142 is formed, and through holes 31 are processed at positions corresponding to the non-display area 4142 of the upper polarizer 30, the lower polarizer 50, and the backlight plate 60;

[0044] b. The OCA optical glue is also cut into a size consistent with the appearance of the display screen 40, and the outer dimension of the glass cover plate 10 is consistent with the appearance of the display screen 40, and then the upper polarizer 30, the OCA optical glue and the glass cover plate 10 are sequentially placed Place it on the display screen 40, place the lower polarizer 50 and the backlight plate 60 under the display screen 40 in sequence,...

Description

technical field [0001] The invention relates to the technical field of display modules, in particular to a structure of a display module for a front camera and a bonding process thereof. Background technique [0002] Electronic products, such as smart phones, have occupied the vast majority of the mobile phone market due to their powerful functions. Display screens are an essential human-computer interaction tool for smart phones, and their performance and aesthetics directly affect the actual experience of users. [0003] Due to the advancement of science and technology, the screens of mobile phones are getting bigger and smaller, and the bezels are getting narrower and narrower. The pursuit of full-screen mobile phones with a screen ratio close to 100% has become a mainstream trend in the world. As the screen becomes larger and larger, the handset and sensors of the mobile phone can be made very small and hidden in the frame, but the front camera of the mobile phone is a m...
