1. A method of fabricating integrated multicolor organic layers for an LED array comprising the steps of:

  • providing an electrical contact layer having a planar surface; and

    depositing a plurality of the different color LED organic semiconductor layers, one at a time, on the planar surface of the electrical contact layer to form a plurality of different color LEDs in a plurality of areas of a selected array includingpatterning a first color LED organic layer of the plurality of organic layers to remain on the planar surface of the electrical contact layer in first areas and to define and expose additional areas in the selected array for additional LEDs laterally separated from the first color LEDs in the first areas, anddepositing a final color LED organic layer of the plurality of organic layers on the planar surface in defined and exposed final areas of the additional areas and on previously patterned color organic layers to form a plurality of final color LEDs in the defined and exposed final areas of the selected array.
