ABSTRACT:
A display driver circuit and method for receiving a display data stream, modifying the display data stream to enhance gray scale performance, and outputting the modified display data stream. The display driver includes a forced state generator for adding at least one forced state to the display data stream to create the modified display data stream. The forced state generator includes a multiplexer and a forced state controller. The multiplexer includes a data input terminal for receiving the display data stream, a first forced state input terminal for receiving first forced state data, a second forced state input terminal for receiving second forced state data, a data output terminal for outputting the modified display data stream, and a pair of control input terminals. The forced state controller includes a pair of control output terminals coupled the control input terminals of the multiplexer. Responsive to signals asserted on the control input terminals, the multiplexer selectively couples its data input terminal, its first forced state input terminal, and its second forced state input terminal with its data output terminal, thus generating the modified display data stream.
