    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.

    摘要: A cholesteric liquid crystal display device (40) comprises a stack of three cells (10), each cell comprising a layer of cholesteric liquid crystal material (19) capable of being switched between a plurality of states including a planar state in which it reflects light with wavelengths in a central band (31) corresponding to red, green and blue, respectively, and in overtone bands (32, 33) on both sides of the central band (31). Each adjacent pair of cells 10 in the stack is held together by a layer of adhesive (42, 43). At least one of the layers of adhesive (42, 43) includes a red dye which is absorbent of light with wavelengths in the overtone bands (32) on the side of the central band (31) of lower wavelength. The red dye improves the perceived red colour of light reflected from the red cell (10R) by suppressing the overtone bands. The provision of the red dye in the adhesive provides several advantages in manufacture.

    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.

    摘要: A display apparatus includes a cholesteric liquid crystal display device comprising a layer of cholesteric liquid crystal material contained between two substrates, each substrate carrying an electrode layer so that the layer of cholesteric liquid crystal material is interposed between the electrode layers. A piezoelectric element is electrically connected to the electrode layers of the cholesteric liquid crystal display device. The piezoelectric element is capable of being manually activated to generate a drive signal which is sufficient to switch the layer of cholesteric liquid crystal material from the planar state to the focal conic state. The substrates are arranged to allow the layer of cholesteric liquid crystal material to be sheared to switch the layer of cholesteric liquid crystal material from the focal conic state to the planar state by manual compression of the cholesteric liquid crystal display device. Thus the display device can be switched without the need for a battery or other power source.
