Getting to know the third generation of Oppo technology to use the camera under the display layer

News unit : Opo was one of the first brands to introduce the Under Display Camera (UDC) technology to the industry in 2019 by building a prototype. But while some other manufacturers – such as ZTE – launched their devices with this technology. have marketed, OPPO has not yet brought this technology to the commercialization stage. Of course, apparently, Oppo’s intention to produce such a product is serious. On Wednesday, August 4, 2021 (13 August 1400), this Chinese company announced one of its latest solutions in this field unveiled. Apparently, the ultimate goal of Oppo is to improve the quality of the screen and the camera inside, so that this technology can be used in the production of a commercial product.

The old panel inside which the selfie camera is placed, as a result of Oppo’s cooperation with BOE company (one of the largest display manufacturers in China) has reached production. Oppo claims that placing the camera inside this screen does not harm the integrity of the screen. In previous similar examples, we have seen that the pixel density of the display has been reduced in the area that covers the selfie camera so that more light can pass through the display layer and reach the camera. But unlike the previous approaches, instead of reducing the density, Oppo has used smaller pixels in the area covering the camera so that the density throughout this OLED panel is equal to 400ppi.

As a result, according to Oppo’s claim, in When working with a smartphone equipped with this technology, there is almost no difference between the area covering the camera and other parts of the display. To prove this claim, Oppo has published an image of a smartphone – which is said to be made with this technology. The display content of this phone is apparently a page of an e-book opened with an e-reader application. It’s not bad to know, due to the white background and the sharpness of the writing, the content of the e-book is the Achilles heel of this type of display, but in the image published by Oppo, there is no apparent weakness.

Arriving Such an advanced technology is not solely dependent on one factor and several components have played a role in its development. According to Oppo, in the construction of this display, transparent materials have been used for wiring instead of common wiring in displays. According to Oppo’s claim, thanks to these transparent materials, the width of the wiring is reduced by 50% and allows more light to pass through.

Another point is related to the circuit of pixels. In the current industrial standard, both pixels are connected with one circuit, which is called one-to-two or one-to-two. But in Oppo’s new solution, each circuit uses only one pixel, which is called a one-to-one architecture. In this way, with only 2% deviation, the control over color acceptability and brightness of the display will be more. It is said that the one-to-one architecture, along with an algorithm known as anti-burn-in, increases the life of the screen by 50% compared to the previous solution.

Oppo claims that in the development of this new technology, in order to improve the quality of photos Taken with a selfie camera, it uses a series of artificial intelligence algorithms, including: refraction reduction algorithm, AWB algorithm (white light balance) and HDR algorithm. The main drawbacks of the images recorded with the cameras under the display are dull photos or excessive brightness of the photos, but according to Oppo’s claim, the artificial intelligence model used in this technology is trained to control such problems.

In order to prove its statements, Oppo published the following image and claimed that this photo was taken with the camera under its new display. Of course, even though this photo was taken under enough light, some color distortions can be seen in parts of it. But in fairness, the quality of this camera is significantly better than the camera under the display ZTE Axon 20 is higher. However, ZTE is not satisfied with the same model and has recently introduced a new generation of cameras under the display in smartphones. title=”Introduction of ZTE Axon 30 5G – with second-generation in-display camera and Snapdragon 870 processor”>Axon 30 is on display. ZTE claims that the density of the covering part of the camera in this phone is also 400ppi and the quality of its camera images has improved compared to Axon 20.

Oppo has not yet announced when the devices equipped with this technology will enter the market. While Xiaomi and Samsung Next week, they will most likely unveil the first smartphones equipped with a camera under their display – namely Mi Mix 4 and Galaxy Z Fold3.
