Abstract

A method of and apparatus for charging select pixel elements of an active matrix liquid crystal display to gray scale voltage levels is disclosed. Which of the pixel elements of the display are to be charged to a first gray scale voltage level is determined. During a scan of the row conductors for the first gray scale voltage level, pixel elements in each enabled row which are to be charged to the first gray scale voltage level are selected. After completion of the scan for the first gray scale voltage level, all of the selected pixel elements in the display are simultaneously charged to the first gray scale voltage level.
