Enhancement of Optical Efficiency in White OLED Display Using the Patterned Photoresist Film Dispersed With Quantum Dot Nanocrystals

Quantum dot (QD) nanocrystals dispersed in photoresist (PR) film was developed and applied to white organic light-emitting diode (OLED) to improve optical power of red color through down-converting of blue and green light. To integrate to white OLED display panel, the QD dispersed photoresist film was prepared in a thickness of 2 μm with high concentration of QDs up to 30 wt%. QDs were dispersed s...
