Abstract:
1. A method for evaluating materials, process conditions, unit processes, and process sequences for organic light emitting diode (OLED) device production, said method comprising: providing a substrate comprising an organic semiconductor material deposited thereon; processing regions on said substrate by combinatorially varying at least one of OLED materials from a group of varied OLED materials, process conditions, unit processes, and process sequences associated with said OLED device production on said substrate, wherein an OLED device comprises at least one of a packaging layer, a cathode layer, an emission layer, a hole transport (HT) layer, and an anode layer over said substrate; performing a first characterization test on the processed regions on said substrate to generate first results; performing a second characterization test on the processed regions on said substrate to generate second results based on said first results of said first characterization test; determining whether at least one of said first results and said second results meet a predetermined quality threshold; and integrating said least one of OLED materials from a group of varied OLED materials, process conditions, unit processes, and process sequences associated with said OLED device production into production of an OLED device based on the determining process.
