Abstract
Quantum Dot technology is playing an increasingly important role in emissive displays including OLEDs, microLEDs and direct view emissive QD-LEDs. Applying Quantum Dot Color Conversion (QDCC) to blue OLEDs or microLEDs, can lead to lower cost, brighter, high contrast displays with wide color gamut. Nanosys has developed new, heavy metal-free QD materials with enhanced blue absorption, high quantum yield and narrow, tunable emission. These attributes enable the fabrication of patternable QDCC films with high (>35%) photon conversion efficiency and BT.2020 color gamut coverage. These new QD materials have delivered greater flexibility to the design of printable inks and formulations. Fabrication can be done using inkjet printing or photolithography, depending on the feature size, mass production and cost requirements of the display product.
