Shen Yiren talks about under-screen cameras: It will take a long time for the technology to mature

According to Jiwei.com on November 13, digital blogger Shen Yiren wrote an article yesterday talking about his views on under-screen cameras.

Shen Yiren believes that under-screen cameras will most likely still not be "mass-produced and sold" on flagship phones in 2021, as the technology will still take a long time to mature. However, it seems that there may be more and more foldable phone models on the market for users to choose from.

Interestingly, this year ZTE launched the world's first mobile phone equipped with an under-screen camera - the A20. It is positioned not as a flagship phone but a mid-range phone, which is similar to what Shen Yiren said.

Earlier, Xiaomi also launched the third-generation under-screen camera technology, which it claimed could be mass-produced, but it did not specify when it would be commercially available.

Lu Weibing, Vice President of Xiaomi Group, President of China, and General Manager of Redmi brand, once talked about the current status of the development of under-screen cameras for mobile phones. Lu Weibing said:

“Everyone is very concerned about the application of under-screen camera technology (CUP: Camera under Panel) in mobile phones, so as to achieve a truly full-screen effect without sacrificing space, but there are still many difficulties in realizing the current technology.

Simply put, it is the contradiction between the screen's PPI and transmittance.

The current screen PPI is about 400, and at this level, the light transmittance of the camera is very low, which seriously affects the photo effect. If the PPI is reduced and the transmittance is increased, there will be a big gap between the PPI of the display area and the PPI of the entire screen, resulting in color blocks in the display area.

Therefore, with current technical capabilities, it is impossible to find an effective solution that takes into account both display and camera effects. Although Xiaomi released a CUP-based technology DEMON in 2019, it is still far from achieving mass production results.

"The entire industry is working hard, and I believe we can overcome this in the future."
