ABSTRACT:
An integrated multicolor organic LED array formed by providing a negative layer and patterning a plurality of different color LED organic layers, one at a time, on the negative layer to form a plurality of different color LEDs in a plurality of areas of a selected array. A first color LED organic layer is patterned on the negative layer in first areas and to define additional areas for additional LEDs laterally separated from the first color LEDs and a final color LED organic layer is deposited in final areas and on previously patterned layers to form a plurality of final color LEDs. Transparent positive contacts are then formed on the final color LED layer in the first and final areas so as to form positive contacts to the first and the final color LEDs.
