ELECTRO-OPTICALLY MATRIX-ADDRESSED ELECTROLUMINESCENCE DISPLAY WITH MEMORY Abstract of the Disclosure It has been discovered for the practice of this disclosure that there is a threshold for switching with light an AC coupled electroluminescence (EL) device within the .DELTA.V of the luminance-voltage hysteresis loop thereof. Practice of this disclosure provides hybrid matrix-addressing of an electroluminescence display device with memory through luminance-voltage hysteresis by "ANDING" electrical and optical signals. It has particular utility for a large aspect ratio display, e.g., a single line display, i.e., one for which there is more information content in one direction than in another direction. YO977-079
