    • Information is written into a matrix-addressed electroscopic display by means of a writing stylus having a magnetic tip, utilized to attract a moveable plate electrode in a selected one of the display matrix cells. A capacitance detector, connected to sequential ones of the column electrodes of the display via a first multiplexer and to sequential ones of the row electrodes of the matrix display via a second multiplexer, detects the change in cell interelectrode capacitance caused by movement of the moveable plate electrode. The capacitance of each display cell is compared with the data for the output state commanded for that cell, to recognize input data sites programmed by the magnetic writing stylus.

    • An improved varistor-controlled multiplexed liquid crystal display of the type having columns of front electrodes and rows of rear electrodes connected in series with combinations of varistor elements and electrical capacitances, has a capacitance of increased magnitude formed in parallel with the capacitance of the liquid crystal layer in each of the multiplicity of the display cells, for reducing capacitive crosstalk between an addressed and unaddressed cell elements of the display. The increased capacitance is provided by auxiliary data electrodes positioned below, and spaced by a thin film dielectric layer from, the reflective rear cell row electrodes of the display, and spaced from the varistor member by at least one thick film dielectric layer. A pair of thick film layers may support the row scan electrodes therebetween, or the scan electrodes may be formed between a single layer and the varistor surface.
    • 具有与可变电阻元件和电容的组合串联连接的前电极列和后电极列的改进的压敏电阻控制复用液晶显示器具有与液晶的电容平行形成的增加幅度的电容 在多个显示单元的每一个中,用于减少显示器的寻址和未寻址的单元元件之间的电容串扰。 增加的电容由辅助数据电极提供,辅助数据电极位于显示器的反射式背电池行电极下方并由薄膜电介质层隔开,并且通过至少一个厚膜电介质层与变阻器构件隔开。 一对厚膜层可以支撑它们之间的行扫描电极,或者可以在单层和变阻器表面之间形成扫描电极。
