    Oppo was one of the first brands to introduce UDC camera technology to the industry in 2019 by building a prototype. But while some other manufacturers - such as ZTE - have launched their devices with this technology, Oppo has not yet commercialized the technology. Of course, it seems that Oppo intends to produce such a product seriously. The Chinese company unveiled its latest solution in this field on Wednesday, August 4, 2021. Apparently, Oppo's ultimate goal is to improve the quality of the display and the camera inside it, so that this technology can be used in the production of a commercial product.

    Old panel with a selfie camera inside, as a result of Oppo's cooperation with BOE (one of the largest display manufacturers In China) has reached production. Oppo claims that placing the camera inside the display does not damage the integrity of the screen. In previous similar examples, we saw that the pixel density of the screen was reduced in the area that covers the selfie camera so that more light could pass through the screen layer and reach the camera. But unlike previous approaches, instead of reducing the density, Oppo has used smaller pixels in the coverage area of the camera to bring the density across the OLED panel to 400ppi.

    As a result, according to Oppo, when working with a smartphone that uses this technology Equipped, there is almost no difference between the camera cover area and other parts of the display. To substantiate this claim, Oppo has released an image of a smartphone that is said to have been made with this technology. The display content of this phone is apparently a page from an e-book that has been opened with an e-reader application. Not bad to know, due to the white background and sharpness of the text, the content of the Achilles heel e-book is such a type of display, but in the image published by Oppo, there is apparently no weakness.

    Achieving such advanced technology depends solely on one factor And several components have played a role in its development. According to Oppo, in the construction of this monitor, instead of the usual wiring in the monitors, transparent materials have been used for wiring. According to Oppo, thanks to these transparent materials, the width of the wiring is reduced by up to 50% and transmits more light.

    Another point concerns the pixel circuit. In the current industry standard, both pixels are associated with a circuit called a one-to-two or one-to-two. But in Oppo's new solution, each circuit uses only one pixel, which is called one-to-one architecture. In this way, with only 2% deviation, control over the color and brightness of the screen will be more. The one-to-one architecture, along with an algorithm called anti-burn-in, is said to increase display life by up to 50 percent over 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, a series of artificial intelligence algorithms have been used, which include: refraction reduction algorithm, AWB (white light balance) algorithm and HDR algorithm. The main drawbacks of images captured with sub-screen cameras are blurry images or excessive brightness of the images, but according to Oppo, the artificial intelligence model used in this technology has been trained to handle such problems.

    Opo has released the following image to substantiate its claims, claiming that it was taken with the camera under its new display. Of course, although this photo was taken in sufficient light, some color abnormalities can be seen in some parts of it. But in fairness, the quality of this camera is significantly higher than the camera under the ZTE Axon 20 display. However, ZTE is not content with the same model and has recently introduced a new generation of cameras under the screen in the Axon 30 smartphone. ZTE claims that the density of the camera cover in this phone is 400ppi and the image quality of its camera has improved compared to the Axon 20.

    Oppo has not yet announced when devices equipped with the technology will enter the market. Xiaomi and Samsung, meanwhile, are likely to unveil the first smartphones with cameras under their screens next week - the Mi Mix 4 and Galaxy Z Fold3.
