ABSTRACT:
A two dimensional array of organic LEDs including laterally spaced, conductive strips positioned on an insulative substrate with a layer of dielectric material positioned thereon and defining cavities therethrough so as to expose areas of the conductive strips within the cavities. At least a layer of active emitter material and a layer of a low work function metal are positioned in each of the cavities on the conductive strips so as to form an LED in each cavity with the conductive strips forming a first electrode of each LED. A layer of metal is sealing positioned over each of the cavities and formed into metallic strips orthogonal to the conductive strips so as to form a second electrode for each of the LEDs.
