METHOD FOR MAKING ORGANIC LIGHT EMITTING DIODE ARRAY

摘要

The disclosure relates to a method of making organic light emitting diode array. A base defining a plurality of convexities is provided. A number of first electrodes are applied on the plurality of convexities. A number of red light electroluminescent layers are transfer printed on a first group of the first electrodes. A number of green light electroluminescent layers are transfer printed on a second group of the first electrodes. A number of blue light electroluminescent layers are transfer printed on a third group of the first electrodes. A patterned second insulative layer is made to cover the number of first electrodes and expose the electroluminescent layers. A second electrode is electrically connected to the electroluminescent layers.

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, wherein the plurality of first electrodes are divided into a first group, a second group, and a third group; transfer printing a plurality of electroluminescent layers on the plurality of first electrodes, wherein transfer printing the plurality of electroluminescent layers comprises:
applying a first electroluminescent film on a first template;contacting the first group of the plurality of first electrodes with the first electroluminescent film;separating the first group of the plurality of first electrodes from the first template so that a plurality of first electroluminescent layers are formed on the first group of the plurality of first electrodes;applying a second electroluminescent film on a second template;contacting the second group of the plurality of first electrodes with the second electroluminescent film;separating the second group of the plurality of first electrodes from the second template so that a plurality of second electroluminescent layers are formed on the second group of the plurality of first electrodes;applying a third electroluminescent film on a third template;contacting the third group of the plurality of first electrodes with the third electroluminescent film;separating the third group of the plurality of first electrodes from the third template so that a plurality of third electroluminescent layers are formed on the third group of the plurality of first electrodes; making a patterned second insulative layer to cover the plurality of first electrodes and expose the plurality of electroluminescent layers; and electrically connecting at least one second electrode to the plurality of electroluminescent layers.
