Through a series of new phones recently released, we can find that full screen has become a development trend of mobile phone screens. In order to maximize the screen ratio of mobile phones, more and more components have been transferred to the screen. As of now, The fingerprint module, light distance sensor, and earpiece have all fully implemented the under-screen technology. Now, only the front camera is a difficult problem to achieve a true full-screen.

　　Although a lot of full-screens have appeared in our field of vision at present, those are only special-shaped full-screens, and the screen ratio cannot reach 100% in the true sense. At present, the mobile phones that truly reach the full-screen use lift cameras. Therefore, the under-screen camera technology has become an inevitable trend in the future development of mobile phones.

Under-screen camera has very high requirements for mobile phone screens. At present, LCD screens and AMOLED screens are common in the market. However, LCD screens require a backlight, which results in its thickness being much higher than AMOLED screens. In terms of light transmission, it will be much worse than AMOLED screen, so it does not meet the standards of the camera under the screen. However, even the AMOLED screen that is much thinner is still too thick for the under-screen camera at the current level, and it needs to be further thinned. However, due to the limited technology and cost at this stage, the current research and development of under-screen cameras Still at the bottleneck stage.

　　At present, the common solutions for the front camera on the market include water drop screen, bangs screen, pop-up camera, etc., but we believe that these are only temporary alternatives. With the continuous development of technology, whether it is the problem of screen thickness or technical cost The problem will be further solved, and it is worth mentioning that Huawei, OPPO, Xiaomi and other manufacturers have already demonstrated their own under-camera technology this year. Although it is not yet fully mature, the true full-screen era will certainly not be far away from us. Too far.
