ABSTRACT:
The invention provides methods of driving a pixel and liquid crystal display panels implementing the methods. The invention generates an ideal data voltage corresponding to a gray level of the pixel, and generates a compensated data voltage corresponding to the gray level according to a polarity change of the pixel. The charging period of the pixel is divided into a first charging time segment and a second charging time segment. The invention charges the pixel by the compensated data voltage during the first charging time segment, and charges the pixel by the compensated data voltage during the second charging time segment.
