29‐2: Pixel‐Level High‐Precision IR‐Drop Compensation for Multi‐Scenario AMOLEDs via Image‐Based Luminance Modeling

To address the uneven brightness and color distortion of AMOLED panels under different On‐Pixel Ratio (OPR ) loads, a brightness compensation method based on image analysis is proposed. A "grayscale‐load‐brightness" correlation model is established to derive the compensated grayscale. Validation on a 6.7‐inch panel demonstrtes that the proposed method reduces luminance non‐uniformity by approximately 90%, and the average ΔE 4 reduces from 2.93 to 0.52. The method requires no additional hardware and is applicable to mobile terminals.
