Abstract
A method for mitigating pooling mura on LCD apparatus and a LCD apparatus are provided. The method is adapted for a LCD apparatus having a plurality of pixels. The LCD apparatus is for displaying frames according to a received original display data, and each of at least a part of the pixels comprises two pixel electrodes to drive a plurality of liquid crystal molecules between the two pixel electrodes. The method comprises changing a corresponding portion of the original display data so as to rotate at least a part of the liquid crystal molecules between the two pixel electrodes of the pressed pixel toward a natural angle; and maintaining another corresponding portion of the original display data. The natural angle is a finally-presented tilt angle of the liquid crystal molecules between the corresponding two pixel electrodes having substantially no potential difference therebetween.
