ABSTRACT:
In a liquid crystal display (LCD) device, two continuous frame image data to be displayed on a display unit are compared with each other by a comparator circuit, and horizontal and vertical synchronizing signals are regulated in accordance with a comparison result. That is, when the two frame image data coincide with each other, the horizontal and vertical synchronizing signals are not output to the display unit through the controller, in order to decrease the number of scannings of frames to be displayed. Also, when the LCD device has a backlight unit and two frame image data coincide with each other, the backlight unit is turned off.
