Abstract:
A method for displaying image signals for use with an active matrix liquid crystal display device wherein a first X driver is connected to gate signal lines for odd lines and a second X driver is connected to gate signal lines for even lines, said method comprising:extracting signals of odd lines in progressive scanning image signals in a first frame and applying voltages corresponding to the signals of odd lines to pixels located along odd and even lines in the liquid crystal display device by operating the first and second X drivers in the liquid crystal display device at the same time and holding the voltages at the pixels so that the same image of an odd line in progressive scanning image signals is formed along the odd line and even line consecutive to the odd line in the liquid crystal device; and extracting signals of even lines in progressive scanning image signals in a second frame, one of the first and second frames being successive to the other, and applying voltages corresponding to the signals of even lines to pixels located along even and odd lines in the liquid crystal display device by operating the first and second X drivers in the liquid crystal display device at the same time and holding the voltages at the pixels so that the same image of an even line in progressive scanning image signals is formed along an even line and an odd line consecutive to the even line in the liquid crystal device; wherein an image is displayed on the liquid crystal display device in two frame periods and one of said extracting signals of odd lines and extracting signals of even lines is performed after the other thereof is performed.
