P‐56: New Brightness Uniformity Tuning Algorithm for LCD Panel with Local Dimming Function

LCD panels with 2D LED backlights often face brightness uniformity issues. This paper introduces an algorithm leveraging LED diffusion characteristics to address this. By projecting patterns and capturing luminance distributions, the algorithm corrects local brightness variations, compensating for mura effects and LED inconsistencies. Experimental results show significant improvements in 2D brightness uniformity, enhancing visual quality in demanding applications.
