We discuss development of QD-LEDs using Cd-free quantum dots. We have achieved patterning in a size practical for high-resolution displays, estimating the expected EQE derived from the optical evaluation of QDs and the equivalent circuit model of QD-LEDs, and directly measuring the carrier injection efficiency based on photoelectrochemical measurement.
