Abstract
A display panel driver is composed of a grayscale voltage generator configured to develop a set of different grayscale voltages corresponding to grayscale levels of pixels within a display panel; and a plurality of grayscale selector driver circuits each of which is responsive to pixel data to select one of the grayscale voltages, and to provide a drive voltage corresponding to the selected one of the grayscale voltages for a selected pixel within the display panel. The grayscale voltage generator is allowed to output the set of grayscale voltages during a first period within a horizontal period, and prohibited from outputting the set of grayscale voltages during a second period within the horizontal period.
