2 µm Full-color Micro-LED Chips Achieved

Saphlux Incorporation, a spin-off company from Yale University, announced the full-color NPQD Micro-LED array with a sub-pixel size of 2 µm, an important breakthrough in AR display developments.
 
Utilizing the patented NPQD technology, Saphlux team created a nanoporous GaN layer inside micro-LED epi-wafer as a natural vessel for quantum dots to be selectively loaded in. A 2 µm full-color micro-LED array was then fabricated and lit up to prove the feasibility.

Saphlux also announced today that the company has started the production of NPQD R1 and T1 micro-LED chips for fine-pitch display customers, who have qualified these chips on their display products and are now entering into the delivery phase. This proves the maturity of the NPQD® technology – a breakthrough in lab research finally evolves into a commercial product.
