摘要： A co-ordinate matrix addressing system is used to address a liquid crystal display cell containing a positive dielectric anisotropy smectic material. For this purpose one or more direct voltage pulses are applied across selected elemental volumes of the display to convert them from a focal-conic scattering state to a homeotropically aligned state. Prior to this all elements are electrically driven into the turbulent scattering state which relaxes into the focal-conic scattering state upon removal of the driving field. The driving field may also take the form of direct voltage pulses. Unselected elemental volumes may be refreshed to substantially their original level of focal-conic scattering by means of a suitable blanking potential applied to both selected and unselected elemental volumes which nevertheless leaves previously restored elemental volumes in the homeotropically aligned state.

摘要： A cholesteric liquid crystal display device (24) has a protective sheet (40) or a stack of protective sheets adhered to the substrate (11) at the front of a stack of cells (10B, 10G, 10R) containing cholesteric liquid crystal material (19). The protective sheet is adhered by a layer of adhesive (40) which is either an adhesive curable by heat or an adhesive curable by light. The adhesive contains a UV blocking agent, for example, a compound based on benzophenone, having a property of reducing the transmission of ultra-violet light through the adhesive. The protective sheet (s) provides protection to the display device and may be made of glass or plastic. Adhering the protective sheet (s) with an adhesive provides the advantages of being much cheaper to implement than laminated glass and of allowing the adhesive to contain the UV blocking agent for UV protection of the cholesteric liquid crystal material.
