OPPO has unveiled its next-generation under-screen camera (USC) technology for smartphones combining hardware innovation and proprietary AI algorithms.

The new solution discreetly places the front-facing camera under the smartphone display, while still maintaining the integrity and consistency of the entire screen during use and in standby.

OPPO has been able to resolve issues such as inconsistent display quality in the screen area above the USC and poor image quality caused by obstruction of the camera by the screen, as well as improving product reliability and lifespan.

Innovative pixel geometry shrinks the size of each pixel without decreasing the number of pixels to ensure a 400-PPI high-quality display, while transparent wiring allows for finer display quality and smoother visual experience.

In contrast to the current industry standard of using one pixel circuit to drive two pixels (“1-to-2”), OPPO has introduced a new solution with each pixel circuit driving only one pixel (“1-to-1”) for improved control of screen accuracy, colour and brightness, particularly when displaying smaller fonts and textural details. The new pixel circuit and optimisation algorithm improves the screen’s lifespan by up to 50%.

With regards to the camera, OPPO’s U.S. Research Institutes has developed a series of imaging AI algorithms including diffraction reduction, HDR and AWB to reduce some of the negative side effects typically found in under-screen cameras, such as blurry images and image glare.

OPPO has also trained its AI diffraction reduction model using tens of thousands of images to control problems caused by diffraction at the light source, allowing users to capture clearer, more natural-looking images.
