Abstract: YO987-097 A METHOD FOR ELIMINATING CROSSTALK IN A THIN FILM TRANSISTOR/LIQUID CRYSTAL DISPLAY The elimination of crosstalk between data lines and pixel cells in a thin film transistor/liquid crystal display is accomplished by applying a data signal to a given data line for a time period less than the standard scan line period of the display, and applying a crosstalk compensation signal to the given data line for the remainder of the scan line period.

Abstract: ELECTRO-OPTICALLY MATRIX-ADDRESSED ELECTROLUMINESCENCE DISPLAY WITH MEMORY 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
