Patent ID: 7652648

Claim:
A method for driving an active-matrix (AM) liquid crystal display (LCD) element by scanning scan lines in a frame, said frame including an odd field and an even field, comprising: sequentially scanning a majority of the scan lines in said odd field of the frame to write a first gray-scale signal voltage into pixels connected to said scan lines; sequentially scanning a majority of the scan lines in said even field of the frame to write a second gray-scale signal voltage into the pixels connected to said scan lines; wherein said sequentially scanning of the majority of the scan lines in the odd field is performed a plurality of times before the next scanning of scan lines in the even field, and then said sequentially scanning of the majority the scan lines in the even field is performed a plurality of times before the next scanning of scan lines in the odd field; wherein said second gray-scale signal voltage has a polarity opposite to a polarity of the first gray-scale signal voltage; and wherein the LCD element has a response time shorter than a time length of said frame.
