This paper proposed a new approach to compensate IR‐Drop on AMOLED panel for CLM (channel length modulation). IR drop will cause the luminance non‐uniformity problem. Moreover, the interaction between IR‐Drop and CLM make the phenomenon worse. If we compensate IR‐Drop but ignore CLM, the color shift happened even though the brightness uniformity gets better. Therefore, CLM compensation value must be analyzed and applied to solve this problem. Experimental results show that our approach improve color shift and keep the brightness uniformity.
