Shen Yiren said earlier this month when preheating OPPO Find X 2 that he would consider mass production. So, there is a high probability that the under-screen camera will not be installed. Lu Weibing also talked about Under-Screen Camera Technology publicly. He stated that with the current technical capabilities, he could not find an effective solution combining display and camera effects. There is still a long way to go to achieve mass production effects.
Lu Weibing said that the application of CUP (Camera under Panel) on smartphones can achieve the real full-screen effect. But there are still many difficulties in the Under-Screen Camera Technology technology implementation, he said. Simply put, it is the contradiction between the screen’s PPI and transmittance.
The current screen PPI is about 400. The light transmittance in the camera is very low, which seriously affects the photo effect. If the PPI is lowered and the transmittance is increased, there will be a large gap. This gap between the PPI in the display area and the PPI of the entire screen will cause phenomena like color patches in the display area.

Therefore, with current technical capabilities, it is impossible to find an effective solution that takes into account both display effects and camera effects. Although Xiaomi released CUP-based technology DEMO in 2019, it is still far from achieving mass production.
Not long ago, Vision and the Terminal Lab of China Academy of Information and Communication Technology jointly released a white paper. The latter was entitled “Observation and Trend Analysis of Smartphone Imaging Technology 2019”. The white paper predicts that changes in the field of smartphone imaging applications in 2020 will mainly focus on the AI algorithm
