Embodiment Construction
[0032] The present invention focuses on new methods and molecular configurations to achieve long-term stability of bistable nematic liquid crystal displays.
[0033] All optically bistable liquid crystal displays reported to date—smectic, cholesteric, or nematic—feature a layer with global alignment, i.e., the alignment of the display between two display substrates. Extend uniformly over the entire area; while the direction of alignment can be different on each substrate.
[0034] In contrast, the present invention chooses a new approach to obtain bistability in conventional twisted nematic LCDs by using non-global alignment geometries. This method surprisingly allows long-term stable and repeatable bistable operation of nematic LCDs.
[0035] Patterned alignment layers on one or both of the substrates of a nematic display enable the generation of different LC configurations that coexist simultaneously and cause bistability in a predefined pixel area (unlike hitherto known N...
