Optical compensation (Demura) is a crucial technology in the production process of active‐matrix organic light‐emitting diode (AMOLED). And with the continuous advancement of micro light‐emitting diode (Micro LED) technology, Demura techniques are also employed to enhance the quality of Micro LED products. This article initially applies an AMOLED full grayscale compensation scheme to perform compensation on a 9.38‐inch Micro LED sample. However, the compensation effect falls short of expectations. Subsequently, an analysis and compensation for the display effects of each grayscale level in Micro LED are conducted, highlighting the phenomenon that the Mura morphology and distribution of Micro LED change under different brightness levels. Finally, two methods are employed to carry out full grayscale compensation for Micro LED, achieving a notably effective compensation outcome. [ABSTRACT FROM AUTHOR] |
