With the development of OLED display technology and the intensified competition in the OLED mobile phone product market, consumers are increasingly demanding the display quality of OLED mobile phones. The higher image quality requirements have prompted panel makers to minimize the impact of mura through process improvement, product design optimization, etc. Low‐gray lens mura is an important one which affect display quality. This paper provides an effective direction for optimizing the process parameters of exposure machine and product design to weakening the influence of lens mura.
