Cost-effective driving scheme for bistable cholesteric displays

For VLSI implementation, low operation voltage and switching current are th e major concerns. Yet, none of the driving schemes published so far has add ressed this combined issue. We studied the electro-optic characteristics of bistable cholesteric displays at the low transition voltage in this paper, and the effect of slew-rate on the maximum output current and average outp ut power in a forthcoming paper. The dynamic responses were measured and an efficient scheme was devised accordingly. The most cost-effective addressi ng time was 4 ms/line using the low-end twist nematic (TN) or super twist n ematic (STN) mixtures.
