ABSTRACT:
In the method of the present invention, a bottom electrode having a planar sheet of conducting material is first deposited on a substrate. A mask is then deposited on the bottom electrode to define wells. For at least first and second ones of the wells defined by the mask, an electroluminescent material is dispensed into the wells. The electroluminescent material dispensed into the first well emits a different spectrum of light from the electroluminescent material dispensed into the second well. In one embodiment of the invention, an isolation layer is deposited over the electroluminescent material after the electroluminescent material has dried. A top electrode is then deposited over the isolation layer. In a display according to the present invention, a plurality of pixels are deposited on a bottom electrode and then a top electrode is provided for energizing the pixels. The plurality of pixels includes first and second pixels, the first pixel having a first mixture of at least two electroluminescent dyes and the second pixel having a second mixture of the electroluminescent dyes. The first mixture differs in the ratios of the electroluminescent dyes from the second mixture.
