ABSTRACT:
The present invention is to provide an apparatus for driving a flat panel display which allows the amount of electrons emitted from a cell to be easily controlled and which performs a stable display gradation processing. To this end, the present invention comprises a shift register for sequentially shifting a video signal input from the exterior in synchronism with a clock signal; a latch for temporarily storing and outputting said video signal which has been sequentially inputted from said shift register; an AND gate for adjusting the time of outputting said video signal output from said latch; and an output driving circuit for inputting said video signal from said AND gate and performing a display gradation control. The present invention allows the amount of electrons emitted from a cell to be easily adjusted so that a 16 step of gradation processing of a display is made possible.
