ABSTRACT:
A full color active matrix electroluminescent display includes an active matrix of pixel electrodes, a broad spectrum electroluminescent phosphor stack placed atop the active matrix of pixel electrodes and a transparent electrode placed atop the electroluminescent phosphor stack. A liquid crystal color shutter device is placed atop the transparent electrode for selectively filtering light from the electroluminescent phosphor stack selectively permitting the transmission of red, green or blue colored light in response to commands from a synchronizing circuit that synchronizes the operation of the shutter with the illumination of selected pixels in the active matrix display. Performance is further enhanced by the use of a double notch filter for the white light emitting broad spectrum electroluminescent phosphor so as to provide it with a uniform response at all waves lengths of interest.
