LED display market Leyard Optoelectronics announced that it developed the world's first mass-produced microLED display that uses quantum dots color conversion technology. Leyard collaborated with Saphlux (of which it owns around 12%).
Leyard adopted Saphlux's NPQD R1 micro LED technology, and have completed the development and testing of the display technology, and now it can mass produce NPQD-powered displays.
The NPQD technology makes use of a nanopore structure to deposit the quantum dots on blue microLED chips. Saphlux says that the nanoporous structure has a unique scattering effect, which enhances light conversion efficiency and the reliability of the quantum dots. The solution also provides a wide color gamut, good color consistency and high efficiency.
It is also reported that Saphlux recently released a microdisplay engine based on its NPQD microLED technology, which achieves 67% blue-to-red conversion efficiency at 2-micron chips.
