ABSTRACT:
A cholesteric liquid crystal display has pixel address circuits (84) with an input (12) for receiving a data signal and a plurality of outputs, wherein each output is for applying a pixel drive signal to a respective portion of the liquid crystal material (20), and wherein the pixel drive signal for each output is independently switchable by the pixel address circuit to each output. This provides spatially-separated sub-pixels, and a number of the sub-pixels can be addressed in order to provide a grey scale output for each pixel. Each pixel drive signal can however be a two-level digital signal.
