Today, Oppo showcased its new under-screen camera technology, two years after building its first working prototype. The company has done a lot of work to improve the quality of the top screen and the image quality of the camera itself, resulting in a product that is much more suitable for commercial products.
The panel is jointly developed with BOE, one of the leading display manufacturers in China. The companies have developed innovative pixel geometry that reduces the size of each pixel in the area above the camera lens, reaching 400 ppi. Oppo has also replaced the traditional screen wiring with a new transparent wiring material, allowing more true light.
The current industry standard is a 1-pixel circuit for driving 2 pixels, also known as 1 to 2. Oppo explained what they did differently - developed a new solution, with each circuit driving only one pixel. It works with "precise algorithmic compensation technology" to provide the brightness of the entire screen to be controlled with a deviation of approximately 2%. USC (Under-Screen Camera Technology) will allow accurate display of smaller fonts when reading eBooks, browsing the news, or navigating with maps.
The US Oppo Research Institute has been working on AI imaging algorithms to ensure diffraction is reduced. Blurry images and image reflections were the main concerns, but Oppo says it trained its AI model using tens of thousands of images to control issues.
Second Generation USC vs First Generation USC
Sadly, the company hasn't revealed when we'll see the technology in out-of-the-box devices, which is rather odd. ZTE has already launched its second-generation phone, and we expect Xiaomi and Samsung to continue next week with the launches of the Mi Mix 4 and Galaxy Z Fold3, meanwhile Oppo is working on prototypes, instead of '' offer consumers a real on-screen experience.
