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.
