The off screen camera is becoming a major technology hotspot in the mobile phone industry. On August 4, OPPO announced its demonstration engineering machine equipped with a new generation of off screen camera technology. This is the second time OPPO has set foot in the field of off screen camera after the release of two generations of "perspective panoramic screen" technology in 2019.

According to the official video, this generation of underscreen front camera demonstration machine adopts a micro curved surface design, which is complete without holes, and the display consistency under the normal display screen is good.

From the technical introduction subsequently released by OPPO, the pixel density of the display area of this generation of off screen cameras has reached the 400PPI level (ZTE Axon 30 is also at this level), and the main screen and the off screen front camera area both use the sub-pixel arrangement commonly known as "Zhou Dongyu Arrangement". Therefore, it can be inferred that this scheme is created in cooperation with BOE and supports independent pixel drive, The nominal full screen brightness difference is less than 2%, and the chromaticity difference is less than 0.8 JNCD.

At the same time, in the part of self taking effect that OPPO attaches importance to, the under screen camera this time incorporates algorithms such as intelligent diffraction removal, intelligent HDR and intelligent white balance calibration to solve the problem of color deviation and blurring in the self taking of previous generation technologies.

Of course, based on the current progress, OPPO's offline camera mass production machine may not be released in the near future. ZTE's Axon 30 and Xiaomi's MIX 4 to be released next week may be the only two choices among offline models in the near future.
