At present, the technical difficulties in the development of under-screen cameras are mainly concentrated in two aspects, the display difference of the lens area compared with the entire screen and the availability of the actual imaging of the camera. Not long ago, the ZTE of the second-generation off-screen camera was released, and targeted improvements have been made on both of these. Oppo, which has invested in research and development in this field very early, also announced its new generation of solutions today. Like ZTE, Oppo’s team also took the two problems mentioned at the beginning as the direction to overcome. The difference is that although Oppo has also achieved theoretically good results, the actual mass production plan has not yet been determined.
First of all, in terms of structural design, Oppo’s new solution reduces the pixel size of the selfie camera area to achieve a higher pixel density of 400ppi (the same as the new ZTE machine). At the same time, the screen wiring has also changed to a transparent material, and its width is reduced by 50% under the support of high-precision technology. The combination of the two can further enhance the visual effect. In addition, compared with the current mainstream single-drive circuit with two-pixel design in the industry, Oppo’s single-circuit-to-single pixel solution combined with algorithm compensation technology can provide better chromaticity and brightness performance with a deviation of only 2%. In scenarios such as reading e-books and browsing news webpages, small fonts and texture details will have better display effects. The life of the micro-panel in the selfie area can also be increased by as much as 50%.
As for shooting performance, Oppo American Research Institute has improved the AI algorithm, so that the new generation of under-screen camera solutions have stronger anti-diffraction, HDR and automatic white balance capabilities. The factory claims that in the future, it will “continue research and development in hardware design and algorithm processing.” The ultimate goal is to bring a “more immersive, true full-screen experience based on the under-screen camera system” to consumers around the world. Considering that the demand for high screen ratio products in the market has indeed been increasing in recent years, I hope Oppo can come up with something real as soon as possible after this announcement.
