Feed-Back Control for the Reduction of Flicker and Gray Scale Errors for Large Panel TFT-LCD

摘要

In this paper, we present a novel method to automatically minimize flicker and gray scale errors across the entire panel by using a compensation scheme of the gray levels of image. Gray scale levels were compensated for the simulated image. The compensated gray scale levels correspond to flickers which are generated by difference of pixel voltage in the odd and even frames. We performed repetitive simulation for the compensated image by our block diagram for the reduction of flickers. Consequently, we confirmed flickers have been reduced by more than 87%.
