For some time now, smartphone companies have been looking for a way to remove the notch and hole-punch design for the selfie camera. Some smartphone makers have adopted a pop-up camera design for this, which may offer a full screen experience but it makes the phone heavier. The under-display selfie camera has emerged as the best ever solution for delivering a full-screen experience. The ZTE company has also launched a few phones (Axon 20 and Axon 30) with under-display selfie cameras, but the drawbacks like poor image quality and not completely hiding the sensor.
Oppo prototyped a device in the year 2019, where the screen above the selfie camera lens was made of a high transparent material with a different pixel arrangement. The device didn’t hit the commercial market, but now the company has announced its next-generation USC technology, which it says will deliver “the perfect balance between screen quality and camera image quality”. Oppo says it includes hardware innovations and artificial intelligence (AI) algorithms to maintain the integrity and consistency of the display when not in use as well as using the camera.
Oppo was able to reduce the size of each pixel without reducing the pixel count. The company has used transparent wiring material or display for this instead of the traditional screen. Oppo claims that for consistent screen color and brightness, Oppo has used a 1 to 1 pixel circuit driving, which means that a single pixel circuit will drive only one pixel and not two. It does this with about 2 percent of the brightness and color accuracy of the display. The 1-to-1 pixel circuit driving technology also improves screen life by up to 50 percent.
The Chinese company has also shared some pictures of the prototype smartphone with USC. No knot or hole-punch can be seen in the display.
At the moment, the Oppo company has not made it clear when it is going to introduce the phone with USC technology.
