We have heard a lot of rumors and leaks regarding the under-display camera technology since the past year. Several manufacturers including the Xiaomi, Oppo, and Vivo were rumored to working on the new technology. However, none of them or any primary OEM succeeded in developing the under-display camera until now. Surprisingly, another Chinese company – Visionox has not only developed but even started mass producing the under-display camera technology.

Visionox InV See uses a transparent OLED device, new circuits, and pixel structures to make it work. The company has adopted a new process and packaging method to remove mass production bottlenecks. Even the metal structure of the body is optimized to increase the transparency of the camera area.
Visionox InV See uses drive circuit and pixel structure design to improve the front-camera efficiency and avoid any interference. A special pixel arrangement is done due to the difference in material transparency and resolution between secondary and the primary display area. (The area where camera resides is termed as secondary.
The new display overcomes the issues of color differentiation, color gamut, and viewing angle abnormality between secondary and primary areas of the display.
Visionox has improved camera transparency by using the new organic and inorganic film materials.
The new display is expected to debut via the Mi Mix 4, but the Huawei and ZTE are not far behind in the race. We expect a smartphone carrying the display to launch before the end of this year. It is a great step forward in bringing full-view display experience to the smartphone users. It would end the interfering notches on the display.
