    摘要: A cholesteric liquid crystal display device (10) comprises a layer of cholesteric liquid crystal material (11) supported by at least one substrate (13; electrode layers (14,15) on opposite sides of the layer of cholesteric liquid crystal material (11); and a light absorptive or reflective layer (17) on the rear side of the layer of cholesteric liquid crystal material (11). To provide non-uniform reflection of light, there is a layer (18) of reflective flakes (19) on the front side of the light absorptive or reflective layer (17), or the reflective layer is shaped to be non-planar.

    摘要: In a cholesteric liquid crystal display device (24), to drive a surface-stabilized layer of cholesteric liquid crystal material into the focal conic state, there is applied drive signal comprising a series of pulses (30, 34, 35, 36, 37, 38, 41). At least one initial pulse has sufficient energy to drive the layer of cholesteric liquid crystal material into the homeotropic state and the subsequent pulses have time-averaged energies which reduce to a minimum level at which the layer of cholesteric liquid crystal material is driven into the focal conic state. This produces a focal conic state of particularly low reflectance, which allows a high contrast ratio to be achieved.
