    摘要: A matrix array type liquid crystal device whose liquid crystal layer is ferro-electric is addressed using strobing pulses applied serially to the members of a set of electrodes on one side of the layer while balanced bipolar data pulses are applied in parallel to the members of a set of electrodes on the other side. The data pulses are twice the length of the strobing pulses. This provides a way of minimising the exposure of the pixels to 'wrong' voltages between consecutive addressings that would tend to drive them to their opposite states.

    摘要: In operating a display device incorporating a matrix addressed smectic cell, a strobing pulse is applied to each row electrode in turn while data pulses are applied in parallel to the column electrodes. The data pulse voltage excursion is less than the minimum voltage V T required to switch the cell. For the entry of complete rows the strobing voltage excursion is made larger than twice V r for fast data entry. For entry of rows in successive segments (e.g. for single character entry) the strobing voltage is of longer duration and is less than twice V T so that successive strobing pulses applied to a single line cannot give rise to spurious switching of unselected pixels.

    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.
