Claim Text:
1. A method of making organic light emitting diode array, the method comprising: providing a base defining a plurality of convexities spaced from each other; forming a plurality of first electrodes on the plurality of convexities; making a patterned second insulative layer among the plurality of convexities to cover first parts of the plurality of first electrodes between the plurality of convexities and expose second parts of the plurality of first electrodes on top surfaces of the plurality of convexities to form a plurality of protrudent portions, wherein the plurality of protrudent portions extend out of the patterned second insulative layer by extending through a plurality of openings of the patterned second insulative layer; applying a plurality of organic light emitting layers on the plurality of protrudent portions comprising transfer printing at least a plurality of electroluminescent layers on the plurality of protrudent portions; and electrically connecting at least one second electrode to the plurality of organic light emitting layers.
