摘要： A liquid crystal display device has a tandem arrangement of two cells. The rear cell is an active silicon matrix backed dyed nematic cell with 180° twist cell affording the possibility of grey scale representations. The front cell is a dyed nematic cell oriented to act as a variable density polariser to absorb the weakly absorbed plane of the rear cell. Control of this absorption is used to optimise the contrast perception in the rear cell under different ambient lighting conditions.

摘要： The array of electrodes of an active silicon backed matrix addressed liquid crystal cell incorporating a black guest dye are arranged in groups whose individual members exhibit contrasting colours, typically red, blue, green and optionally yellow, whereby a polychromatic image can be displayed.

摘要： A data terminal uses as its display device a liquid crystal display formed on one face of a thin silicon slice. The slice has formed in it the controlling circuitry, based on MOS devices, for the display and some at least of the associated circuitry. The control means also includes a microprocessor with its associated memories and interfaces.

摘要： A curtailed drive scheme is disclosed for a matrix array liquid crystal display cell in which the field developed across each picture element is maintained for only a fraction of the time interval between consecutive addressings. This reduces the effects of differences in time constants across the display for addressing schemes in which the average time constant is short compared with this time interval between consecutive addressings.
摘要翻译： 公开了一种用于矩阵阵列液晶显示单元的缩减驱动方案，其中在每个像素之间产生的场仅被维持在连续寻址之间的时间间隔的一小部分。 这减少了与连续寻址之间的该时间间隔相比平均时间常数较短的寻址方案的显示器上的时间常数差异的影响。
