Flat cathode-grid type video display screen using field effect for electron emission has a temporary storage element such as capacitor for every pixel for stabilizing its luminance

摘要

A first set of drivers drives lines and a second set of drivers drives columns. The intersection of a column and a line defines a location of a pixel of a screen. A temporary storage element such as a capacitor (26) is provided for every pixel of the screen for controlling luminance of the pixel. An Independent claim is included for: (a) a luminescent video flat display screen
