“…As previously reported, [13] NanoPattern Technologies, Inc. is commercializing a photopatternable QD ink for high resolution display applications. Figure 3 showcases the resolution, high absorption cross section as demonstrated by a much thinner optical density of 2 at >10 m thickness, and the >90% film Photoluminescent Quantum Yield (PLQY) values that have been demonstrated.…”

Quantum Dot downconverters can provide a scalable solution to tri‐color high‐resolution microLED and OLED displays by converting monochrome displays using photopatternable red and green QDs. Using internal measurements collected at NanoPattern Technologies, Inc. we model and discuss the practical wall plug efficiencies for downconverted InGaN blue microLED displays. In the range of 5 μm pixel sizes, using uncorrected 65 % film PLQY, the downconverted InGaN red emitter achieves a comparable external quantum efficiency compared to a direct red emitting AlInGaP when compared at practical current densities for microLED drivers.
