"single organic layer... 2 standard aluminum electrodes also acting as microcavity mirrors... replaces traditional complicated organic stacks, indium tin oxide, complex color-mixing chemicals... avoids complexity/ cost of mixing red, green, blue dopants by using single, metal-free, sky-blue thermally activated delayed fluorescence... adjusting cavity layer thickness reinforces certain colors... fits existing vacuum-deposition lines... reflective/ flexible surface compatible... future: improve brightness, efficiency, stability"
