Image flicker will cause the degradation of image quality of liquid crystal display. In this paper, the image flicker of polymer‐sustained‐alignment liquid crystal display panel is studied experimentally. We found that optimizing Vcom voltage can reduce image flicker. In addition, image flicker is sensitive to the low‐level gate voltage Vgl and high‐level gate voltage Vgh. Vgl and Vgh should be carefully...
