Quantum Dots Shrink Pixels from 30 Microns to 4 Microns | NextBigFuture.com

Nanoco Technologies and Plessey Semiconductors have partnered to shrink the pixel size of monolithic microLED displays using Nanoco’s cadmium-free quantum-dot (CFQD quantum dots) semiconductor nanoparticle technology. Using its existing gallium nitride (GaN)-on-silicon monolithic process, Plessey will integrate the CFQD quantum dots into selected regions of blue LED wafers to add red and green light, shrinking the smallest practical pixel size from today’s 30 µm to 4 µm, a reduction of 87%. the quantum dots are applied onto microLED arrays using an inkjet process, for which the two companies will file a joint patent. “Quantum dots offer the best solution for
