Abstract
In this paper, we correct the necessary image algorithm such as sub‐pixel rendering (SPR) and de‐mura (DMR) for under‐display camera (UDC) area on AMOLED display. Because the wiring of TFT pixel circuit and structure are different between UDC and normal area, it results in color shifts and brightness nonuniformity in the UDC area. The new correction algorithms we propose are based on the existing architecture, distinguish the position coordinates of the two areas, and give a new correction method for the UDC area. The new algorithms have been integrated into the new DDIC NT37701 and have been mass‐produced for smartphone products.
