Abstract

This article reports the highly color stable white organic light-emitting diodes (WOLEDs) having a high color rendering index (CRI) utilized by simple-hybrid structures involving emitting layers (EMLs) of phosphorescent yellow polymer and a thermally deposited fluorescent blue. To derive the yellow EML, a highly soluble red dopant is developed and used with a highly soluble green co-dopant. Using a simple-hybrid structure, the emission tuned WOLEDs are successfully demonstrated with a high CRI of 93 and a highly color stable CIE 1931 coordinate over the full driving voltages from (0.33±0.00, 0.35±0.01) to (0.42±0.01, 0.44±0.01) depending on the blue EML host.
