Zenithal Bistable LCDs use a standard twistednematic geometry but with a surfacerelief grating as one of the alignment layers. Best operation results from operating in a normally whiteTN mode. An improved white state is possible by tuning the cell gap. The consequences of this change on device performance and cost are discussed.
