Claim Text:
1. A method of making organic light emitting diode array, the method comprising: providing a base having a plurality of first electrodes on a surface of the base; depositing a first organic layer on the surface of the base so that the first organic layer is electrically connected to the plurality of first electrodes; applying a first organic light emitting layer on the first organic layer; providing a template with a first patterned surface; attaching the first patterned surface of the template on the first organic light emitting layer and pressing the template toward the first organic light emitting layer; forming a second patterned surface on the first organic light emitting layer by separating the template from the first organic light emitting layer, wherein a plurality of first protruding structures, a plurality of second protruding structures, and a plurality of third protruding structures are formed on a surface of the first organic light emitting layer away from the base; depositing a second organic light emitting layer on each of the plurality of second protruding structures, and depositing a third organic light emitting layer on each of the plurality of third protruding structures; forming a second organic layer to cover the plurality of first protruding structures, the second light emitting layer, and the third light emitting layer; and forming a second electrode electrically connected to the second organic layer.
