Mobile phones have become the most important interactive devices in people's lives. Especially with the popularity of smart phones, mobile phones are not only used as communication tools, but also as a medium for people to obtain information, live shopping, locate and entertain. In order to adapt to increasingly rich usage scenarios and people's deeper pursuit of a friendly interface, there are greater requirements for the size of the screen. But limited to handheld devices, the screen cannot be enlarged infinitely. Then, in the limited size, maximizing the display area can bring better user experience. When you don’t need to take photos or videos, you can hide the camera without affecting the display area, and you can use the camera without being affected when you need to take photos, so as to bring a better user experience. In order to achieve this goal, it is necessary to put the camera under the display.

Since the camera is a material module, it cannot be blocked during use and requires a lot of light to enter, so the existing technology uses a mechanical structure to hide the camera (such as a pop-up camera, a flip camera or a slide camera) . The above-mentioned methods are relatively complicated in mechanism, the reliability is not high, and they cannot be dustproof and waterproof. In addition, there is another method in the existing technology, which is to use the camera under the screen, and use the light transmittance of the OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) screen to place the camera under the screen, but this method is because the OLED display emits light. The existence of pixels affects the entry of light when taking pictures, resulting in poor imaging quality, and this method can only use OLED screens.
