ABSTRACT:
A gray voltage generator for liquid crystal display can control a viewing angle of the liquid crystal via a shift of a gray reference voltage by adjusting a size of the gray reference voltage level, can compensate kick back voltage and threshold voltage of the liquid crystal by fine adjustment of the gray reference voltage level, and can prevent an abnormal screen displayed in the liquid crystal display during an internal setup time when a video signal is not produced after power is applied to electrical equipment including its liquid crystal display.
