On-demand Patterning for Organic Light-emitting Diodes Using Laser Irradiation

Abstract
We investigated the patterning of organic light-emitting diodes using a blue laser irradiation after making uniform device. Laser patterning was carried out in the atmosphere after the organic layer was deposited. The laser irradiation part was quenched, and it was shown that optional patterning was possible. This technique is expected as a fabrication technique for on-demand pattern emission.
