Oppo has demonstrated the latest iteration of its under-screen camera technology, which allows for the positioning of a selfie camera beneath the display "without endangering the screen's integrity," according to the company. Unlike past efforts that reduced pixel density in the screen section surrounding the camera to enable more light through, Oppo is using fewer pixels to maintain the same 400-PPI sharpness as the rest of the OLED panel.
According to Oppo, users would notice "almost no visual difference between the [under-screen camera] area and the rest of the screen during typical use," resulting in a "much more immersive visual experience." The company has shown off a photograph of a prototype phone running an e-reader app, which would be the worst-case situation for previous under-display cameras, thanks to the white background and crisp letters.
Oppo provided the following example photograph to demonstrate the camera's quality:
There appears to be some color artifacts in specific regions, and it's only one example shot in good light. It does, however, appear to be significantly superior to the original under-display camera, which was seen on ZTE's Axon 20 5G.
ZTE, on the other hand, has an advantage over Oppo in that it has already released a phone, and its newer Axon 30 is said to be more technologically advanced. The camera portion of the screen, according to ZTE, has the same 400-PPI density and improved camera quality as the Axon 20.
Oppo has been working on under-display cameras for a long time, presenting the world's first prototype at MWC Shanghai in 2019, but it will eventually need to include one in a commercial product. For the time being, it's difficult to comment on technological developments without seeing a prototype firsthand.
