摘要： The invention provides a ferroelectric liquid crystal display with uniformly spaced greyscale levels. The invention uses a bistable ferroelectric liquid crystal display formed by a layer of chiral smectic liquid crystal material between two cell walls. The walls carry e.g. line and column electrodes to give an x,y matrix of addressable pixels, and are surface treated to provide bistable operation. Each pixel may be divided into subpixels thereby giving spatial weighting for greyscale. Temporal weighting of greyscale is obtained by switching a pixel to a dark state for time T1 and a light state for time T2. When T1 and T2 are not equal, four different greyscales are obtainable; i.e. dark, dark grey, light grey, and light. The present invention provides a required uniform spacing of greyscale levels by addressing each pixel two or more times in one frame time. Each pixel is blanked then strobed, two or more times in each frame time; the relative times between blanking and strobing, at least four different time periods, are varied to give the desired greyscale levels. The temporal and spatial weighting may be combined to increase the number of obtainable greyscales. Further, the relative intensity between adjacent subpixels may be adjusted to vary the apparent size of the smallest subpixel; this is useful when subpixel size is near to manufacturing limits.

摘要： A ferro-electric liquid crystal cell is addressed by row and column electrodes forming an x,y matrix of display elements. A strobe waveform is applied to each row in sequence while appropriate data waveforms are applied to all the column electrodes. At each display element the material receives an addressing waveform to switch it to one of its two switched states depending upon the polarity of the addressing waveform. The switching characteristics of ferro-electric materials depend upon the shape of the addressing waveform. Two different shapes of addressing waveforms are used to produce two different and separated switching characteristics (FIG. 3). Al least one switching characteristic curve may exhibit a minimum response time at one voltage value, and the display is operated at voltages above this. The data waveforms are alternating positive and negative pulses of period 2ts. The strobe waveform has a zero for one time period ts followed by a unipolar voltage pulse of duration greater than ts, e.g. 1.5ts or more. This results in an overlapping of addressing in adjacent rows, i.e. the end of a strobe pulse on one row overlaps with the beginning of a strobe pulse on the next row. The display elements may be switched into one of their two states by one of two strobe pulses of opposite polarity. Alternatively a blanking pulse may switch all elements to one state and a strobe used to switch selected elements to the other state.
摘要翻译：铁电液晶单元通过形成显示元件的x，y矩阵的行电极和列电极来寻址。每个行按顺序施加选通波形，同时将适当的数据波形应用于所有的列电极。在每个显示元件处，材料接收寻址波形，以根据寻址波形的极性将其切换到其两个切换状态之一。铁电材料的开关特性取决于寻址波形的形状。使用两种不同形状的寻址波形来产生两种不同和分离的开关特性（图3）。至少一个开关特性曲线可以在一个电压值处呈现最小响应时间，并且在高于该电压的电压下操作显示器。数据波形是周期2ts的正负脉冲。频闪波形在一个时间段ts之后具有零，随后是持续时间大于ts的单极电压脉冲，例如。 1.5t以上。这导致在相邻行中寻址的重叠，即，一行上的选通脉冲的结束与下一行上的选通脉冲的开始重叠。可以通过相反极性的两个选通脉冲之一将显示元件切换成它们的两个状态之一。或者，消隐脉冲可以将所有元件切换到一个状态，并且选通用于将所选元件切换到另一状态。

摘要： A liquid crystal display comprises a liquid crystal material layer contained between transparent slides which carry electrodes arranged in lines and columns to form an x, y matrix with x, y intersections. The liquid crystal layer at the intersections are turned on line by line by a blanking voltage, turned off by application of a zero voltage, and held at a threshold voltage at other times. The voltages are applied from a two phase supply in the form of two sinusoidal waves spaced 60.degree. apart in phase. Threshold voltages at an intersection are maintained by applying one of the two waveforms to x electrodes and a zero voltage to y electrodes. A zero voltage at x, y intersections is arranged by applying the other of the two waveforms to both x, y electrodes.

摘要： A ferroelectric liquid crystal cell is controlled by applying a strobe pulse and a data pulse to the cell, the magnitude of the data pulse being modulated in order to control the resultant pulse applied to the cell. The resultant pulse includes a pre-pulse on one polarity and a main pulse of the opposite polarity. When applied to a liquid crystal cell of stepped thickness, the application of data pulses of different magnitudes switches regions of different thicknesses of the cell so as to provide grey level capability.
