Session: QD PL-uLED
High Optical Density, High Efficiency Quantum Dot Photoresist for microLED applications
Invited
Description:
Quantum dot color converters (QDCCs) are a leading technology for enhancing the gamut and efficiency of displays, notably in QD-OLED TVs and monitors. However, cadmium-free QDs require thick layers for effective color conversion. Our novel inorganic photoresist densely packs InP QDs, achieving over 60% PLQY and optical density of 1 at less than 10 µm thickness, advancing QDCCs for high-performance microLED displays. Patterning of 5um pixels is also demonstrated.
