Method of making organic light emitting diode array

摘要

A method of making organic light emitting diode array includes following steps. A base having a number of first electrodes on a surface of the base is provided. A first organic layer is located on the surface of the base to cover the first electrodes. A template with a first patterned surface is provided, wherein the first patterned surface includes a number of grooves with different depths. The first patterned surface of the template is attached on the first organic layer and separated from each other, wherein a number of protruding structures with different heights is formed. An organic light emitting layer is deposited to cover the protruding structures. A second organic layer is located on the organic light emitting layer. A second electrode is applied to electrically connected to the second organic layer.

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, wherein each of the plurality of first electrodes is located between adjacent two barrier walls; depositing a first organic layer on the surface of the base to cover the plurality of first electrodes, wherein the first organic layer is a continuous structure, and a material of the first organic layer is Polyaniline or Copper Phthalocyanine; providing a template with a first patterned surface, wherein the first patterned surface comprises a first groove, a second groove, and a third groove, and a first depth d1 of the first groove, a second depth d2 of the second groove, and a third depth d3 of the third groove are different; attaching the first patterned surface of the template on the first organic layer and pressing the template toward the first organic layer, wherein the template is pressed towards the first organic layer at room temperature in a vacuum environment of about 1×10−1 millibars to about 1×10−5 millibars, a pressure applied on the template is about 2 pounds per square inches to about 100 pounds per square inches, and the pressure is applied on the template for about 2 minutes to about 30 minutes; forming a second patterned surface on the first organic layer by separating the template from the first organic layer; depositing an organic light emitting layer on the second patterned surface of the first organic layer; forming a second organic layer on the organic light emitting layer; and forming a second electrode electrically connected to the second organic layer.
