ABSTRACT:
A liquid crystal display is driven at, for example, a frame frequency of 100 Hz or higher. There are provided a base-4 frame counter2and a source control signal generator section controlling the polarity of the liquid crystal in pixels so as to alternately repeat, for each frame, a horizontal reversal once every m lines (m is 2 or a greater positive integer) and a horizontal reversal once every m lines after shifting the polarity of the lines in the preceding frame by n lines (n is a positive integer equal to a half or less of m). The provision achieves a liquid crystal display and a method of driving the display, addresses insufficient charging at higher frame frequencies and accomplishing higher display quality.
