Abstract:
1. A method of processing an organic light emitting diode (OLED) device, said method comprising: identifying a first sub-group of organic light emitting diode (OLED) materials from a group of varied OLED materials during a primary combinatorial screening process, said first group of OLED materials having a first set of characteristics; characterizing said first sub-group of OLED materials deposited on a transparent substrate, wherein said first sub-group of OLED materials deposited on said substrate comprises at least one of a packaging layer, a cathode layer, an emission layer, a hole transport (HT) layer, and an anode layer; selecting a second sub-group of OLED materials based on operational performance of said first sub-group of OLED materials during a secondary combinatorial screening process; and integrating said second sub-group of OLED materials into OLED devices to test operational performance of said OLED devices during a tertiary combinatorial screening process, wherein a combinatorial screening process comprises varying at least one of OLED materials, process conditions, unit processes, and process sequences associated with selecting optimal materials and manufacturing sequences for producing said OLED devices.
