Aledia and QustomDot to co-develop full-color micro-LED displays
Aledia S.A of Echirolles, near Grenoble, France (a developer and manufacturer of 3D micro-LEDs for display applications based on its large-area gallium nitride nanowires-on-silicon platform) and Belgium-based Ghent University spin-off QustomDot (which combines quantum dot synthesis, surface engineering and ink/photoresist formulation into patterned color conversion layers for micro-LED displays) have joined forces to leverage their expertise and co-develop a full-color micro-LED technology that will address the video wall and luxury TV markets.
Aledia has unique 300mm GaN-on-Si nanowire technology that is said to unlock scalable manufacturing of micro-LEDs, enabling highly efficient blue micro-LEDs to be produced for a first range of high-end micro-LED products.
“We have worked for several years on combining our unique GaN nanowire micro-LED platform with quantum dots, taking advantage of the exceptional color quality of quantum dots; however, in the past the quantum dots have often been a limiting element in the final micro-LED performance,” says Aledia’s CEO Giorgio Anania. “Together with QustomDot’s innovative quantum dot (QD) inks, we believe a higher-performing range of micro-LED products could be within reach,” he adds.
Belgium-based QustomDot leverages its quantum dot platform to enable what is claimed to be the most all-round and reliable heavy-metal-free color conversion solution on the market. “While many technologies are being developed in the field, we believe that Aledia’s ambition and vision can drive the micro-LED market to the next phase,” comments QustomDot’s CEO Kim De Nolf. “We have found that both our technology platforms are a great fit for this emerging market,” he adds. The joint collaboration will initially target the video wall and luxury TV markets, and first prototypes are expected to roll out in early 2023.
