We report and discuss the challenges to realize a nanoLED based display from the perspective of materials and processes. Additionally, we report on an active‐matrix nanoLED display using heavy metal free Quantum Dots (QDs) patterned by photolithography, realized by combining materials and process technology.

This paper reports on the potential of quantum dot light emitting diode (QD-LED) as a future display technology and the challenges to realize a QD-LED based display from the perspective of materials, processes, and optical design requirements. We give an update on development of active matrix QD-LED displays using Cd free QDs.
