Image display system

An image display system includes an array of pixel elements, column drivers, row drivers, a look up table memory, and a controller. Input video data including gradation information of an input image is received. According to rules of a look up table, the input video data is assigned to multiple groups, binary signals for respective groups are generated using the respective input video data assigned to each group, and an order of the binary signals within at least some groups is rearranged to form respective binary control signals without conflicting state changes. The controller transmits the binary control signals to the column drivers and transmits a select signal that selects the row drivers. Alternatively, the controller transmits the binary control signals to the row drivers and transmits a select signal that selects the column drivers. The select and binary control signals are in synchronization with a clock signal.
