Abstract
As a breakthrough technology, UDC (Under‐Display Camera) can achieve full display, also can increase panel proportion of mobile phones. It is the most likely way to balance the contradiction between front camera and display integrity settings. However, due to the design difference between the main and UDC areas, the display consistency is an important factor affecting the display effect and production yield of UDC panel. To solve this problem, this paper analyzes the reasons for the inconsistency between the main and UDC areas, as well as the defects of the current main solutions. An advanced debug scheme is proposed. It can significantly improve the accuracy of display brightness of UDC area, so as to improve the display effect of UDC panel.
