OPPO shows an insight into their new generation of "sub-display cameras". They showed the first generation in 2019 at the MWC. How far they have come to this day, I will explain to you in the following lines.
"UDC", "USC" or simply "no more notch". There are many expressions or names for a camera that sits under the screen and thus offers an interference-free display experience. OPPO has chosen the term "USC", which stands for the designation "Under-Display-Camera".
Most recently, the manufacturer ZTE showed with the Axon 20 5G a finished smartphone of this fascinating technology, whereby the quality of the front camera, among other things, was not really satisfactory. Therefore, OPPO is still waiting a little with its smartphones. So far it has only been about Prototypes that initially do not come onto the market. There is currently no confirmation as to when we will see a first smartphone with OPPO's new technology. But first let's look at the improvements of the last one Prototypes.

The front camera redefined
Front cameras on smartphones have so far been available in an elongated notch, in a punch hole or in a pop-up system. In the past, OPPO itself relied on pop-up systems for its smartphones. Like almost everyone else, they now rely on front cameras in the form of a small punch hole in the display.
In OPPO's new approach, the camera is supposed to disappear permanently behind the display, both during use and in standby mode. What worked rather moderately at ZTE is now to be made possible through an innovative interplay of components with the help of OPPO's AI algorithms. What exactly? No more sacrifices in terms of camera quality. However, this is very difficult with "under-display camera systems".

Thanks to the new advances made by OPPO, the rather poor display quality in the area of the front camera is now a thing of the past. There should also be no impairment of the image quality, regardless of whether it is video or photos.
OPPO's solution should convince
As already mentioned, OPPO prefers to wait a while than to bring unfinished or poorly tested technologies to market too quickly. You saw that recently on the Flash Charge Day 2021. With their new USC 2.0 technology, they rely on both modern design approaches and powerful algorithms.

Increased pixel density satisfactorily
OPPO's new solution offers pixel reduction where the camera sits under the display. Without sacrificing the number of pixels (PPI). in the ProIn total, this area is a whopping 400 pixels despite the camera under the display pro Customs service.
Wiring now transparent
You read that right! The wiring for the display is now transparent. The new innovative wiring of the display was also increased by 50 Procent in width reduced. This is to ensure both better display quality and a smoother visual experience.

Improvement of the display
The Chinese manufacturer relies on a specially developed screen technology. A pixel circuit for two pixels would be usual, but OPPO relies on one pixel circuit each pro Pixels (1-to-1). A "compensation algorithm" also developed by OPPO is then used. This ensures that the image signal in the camera area is corrected precisely. This allows the color and brightness values to be adjusted to match those of the entire display.
The end result should be that all things that have fine texture details, such as texts in e-books, can be displayed losslessly and exactly like on the rest of the display.
Massively increased reliability and service life
As stated beforeproWith the introduction of OPPO's "1-to-1" pixel circuit and optimization algorithm of the next-generation "under-display camera", there is also one by up to 50 Procent longer display life.
New AI algorithms from the OPPO research institute
Since the photo quality has always suffered in past iterations of USC technology, OPPO is now trying the previous ones using AI algorithms developed by its own research institute in the USA Proto eliminate the problem of the invisible front cameras. The new software should improve a lot here. OPPO trained here for its AI model with over tens of thousands of images so that the results are not overshadowed by light rays from the pixels. In the pictures below you can see two selfies taken with the new front camera under the display:
