A highly color-stability white organic light-emitting diode by color conversion within hole injection layer

Optics Express, 2007
We demonstrated a novel-structure white organic light-emitting devices (WOLEDs) composed of a greenish blue fluorescent emitting layer and a red fluorescent dye-doped hole injection layer. The spectra of WOLEDs show no change at a wide range current density operation and long-term continuous operation.

P‐12.2: Inkjet‐printed Quantum‐dots Photopolymers for Full‐color Micro‐LED Displays

, 2021
Quantum dots (QDs)-based color-conversion micro-LED displays require simple and cost-effective technology to remove blue excitation light. We demonstrate a simple process to remove the residual blue light from the color conversion layer by using QDs ...
