Saphlux is a Connecticut-based startup specializing in gallium nitride (GaN) light engine products and microLED display technology. The company's core innovation is its patented nanoporous quantum dots (NPQD) technology, which embeds quantum dots into nanopores in GaN to enable direct color conversion on blue microLED wafers. Saphlux's NPQD process allows for the creation of red and green quantum dot conversion of blue GaN microLEDs at pixel pitches below two microns, achieving full-color monolithic light engines.
The company offers a range of products including its T1 and T2 series micro-displays specifically designed for augmented reality (AR) and virtual reality (VR) applications. In August 2023, Saphlux demonstrated a 0.39-inch full-color microLED display (T1-0.39 RGB) capable of a maximum white brightness of 250,000 nits and wide color gamut. The T2 series, announced in January 2024, features a 70% improvement in color gamut and 40% increase in brightness compared to its predecessor. Saphlux also produces NPQD-based red microLEDs for public information displays and is developing a 0.26-inch full-color microLED micro-display meeting the DCI-P3 color standard with an expected peak brightness exceeding 500,000 nits.
Key customers and partnerships
Saphlux has established partnerships with blue microLED manufacturers to create innovative AR solutions. The company works with OEMs to design AR glasses, offering flexibility in terms of optics, brightness, and overall look and feel. In 2017, Leyard, a major player in the LED display industry, invested in Saphlux, acquiring a 12.37% stake to jointly develop quantum dot and gallium nitride-related technologies for microLED displays. Saphlux has been shipping high-volume NPQD-based red microLEDs for public information displays and plans to begin shipping its T1-0.12 Red products to customers in the AR/VR industry.
