Patent ID: 8054271

Claim:
A method of driving a pixel, comprising: generating a compensated data voltage for the pixel based on a gray level of the pixel and a polarity change of the pixel; generating an ideal data voltage for the pixel based on the gray level, wherein the ideal data voltage is of the same polarity as the compensated data voltage, and the ideal data voltage is generated according to an ideal gamma curve; dividing a charging period for one sub-frame of the pixel into a first charging time segment and a second charging time segment, wherein the first charging time segment is prior to the second charging time segment; charging the pixel by the compensated data voltage during the first charging time segment; and charging the pixel by the ideal data voltage during the second charging time segment; wherein the compensated data voltage is generated according to a first compensated gamma curve when the polarity change of the pixel is from negative to positive, and the compensated data voltage is generated according to a second compensated gamma curve when no polarity change occurs in the pixel and the polarity of the pixel is positive.
