Quantum dot color conversion technology will lead to displays with higher brightness, color tunability and viewing angles. We have developed Cd‐free QD‐photoresist (QDPR) formulations containing specially designed QDs with enhanced blue absorption and green/red emission to achieve >90% BT.2020 coverage at feature resolution of µ10 mm. QDPR devices can be fabricated on existing lithographic equipment, making this technology attractive for all kinds of displays including LCD, OLED and microLED.
