Abstract
An operating method for a color display system including an active matrix bistable liquid crystal display (LCD) having a plurality of pixels arranged in a matrix based on color data and status bits corresponding to each of the pixels stored in a memory includes steps for generating voltage data corresponding to the pixels based on the color data and the status bits stored for each of the pixels, converting the voltage data to drive signals suitable for driving the active matrix bistable LCD, and applying the drive signals to the active matrix bistable LCD. In an exemplary embodiment, the active matrix bistable LCD is a Cholesteric LCD. Advantageously, the generating, converting, and applying steps are repeated for a corresponding pixel N times, where N is an integer established by the status bits.
