ABSTRACT:
A graphics controller for a color display system having a bistable liquid crystal display (LCD) for displaying a plurality of pixels arranged in a matrix includes a memory device for storing color data and status bits corresponding to each of the pixels, and a generating device for generating voltage data corresponding to the pixels based on the color data and the status bits for each of the pixels. In an exemplary case, the bistable LCD is a Cholesteric LCD. Preferably, the generating device has a first mode of operation in which the data corresponding to the pixels is generated for each corresponding pixel and a second mode of operation in which no data is generated; the generating device switches from the first operating mode to the second operating mode when all of the status bits for all of the pixels are zeros.
