摘要： Novel liquid crystal materials are provided having the general formula ##STR1## where A is a 4-alkylphenyl group and B is a 2-(6-alkyl)naphthyl group, or vice versa, wherein the alkyl groups in A and B may be the same or different. These materials have a dielectric anisotropy sign change at moderate frequencies, i.e., in the range 1kHz to 50kHz and are thus useful for twisted nematic device cells of the frequency switching type.

摘要： A cholesteric liquid crystal display device comprises three cells each comprising a layer of cholesteric liquid crystal material and an electrode arrangement capable of providing independent driving of a plurality of pixels across the layer of cholesteric liquid crystal material by respective drive signals. A drive circuit applies a respective drive signal to each pixel to drive the pixel into states which are variable to provide a reflectance varying within a predetermined range of reflectances. The drive signals involve a combination of two drive schemes to provide reflectances in different portions of the range. In particular, (a) when providing a reflectance in a first portion of higher reflectance, the drive signals comprise a first waveform shaped to drive the pixel into a stable state, the waveform having a shape which is variable to provide a stable state having a varying reflectance; and (b) when providing a reflectance in a second portion of lower reflectance, the drive signals comprise a second waveform shaped to drive the pixel into the homeotropic state and the planar state alternately, the periods of time during which the pixel is driven into the homeotropic and planar states being variable to provide a varying average reflectance as perceived by a viewer. Such a combination of drive schemes allows a good contrast ratio and color gamut to be achieved because of the use of the homeotropic state but only increases the power consumption by a relatively small amount as the homeotropic state is only used for a portion of the pixels.
