ABSTRACT:
The present invention relates to a high voltage output circuit for driving a gray scale flat panel display. The high voltage output circuit eliminates the inaccuracies of prior art output circuits by using a plurality of transistors to eliminate a dead band level within the output circuit. The output circuit is also less expensive than prior art output circuits since a level translator is not required.
