Abstract

A liquid crystal display (LCD) that may include: a plurality of transistors groups forming a pixel array of said LCD, wherein the transistors groups are independently controllable; a plurality of backlight units, forming a backlight surface of said LCD, wherein the backlight units are independently controllable; a data refresh module configured to periodically refresh data at said groups of transistors, at a specified order, over a refresh cycle time; and a backlight control module configured to periodically dim the backlight units at said specified order over a backlight cycle time which is substantially shorter than the refresh cycle time.
