ABSTRACT:
An active matrix addressed liquid crystal display is described, each liquid crystal cell within the display having two electrodes each carried on a surface of a different one of two insulating plates. Each cell is connected via a respective transistor to a pair of address lines each address line within a pair being connected to different cells within the array, and each line within a pair being carried on a different plate. Synchronized electrical pulses are applied to the address lines to switch on selected cells within the array, the sense of the pulses on one of the lines being periodically changed.
