Raysolve Optoelectronics was spun out of the Hong Kong University of Science and Technology (HKUST) is developing monolithic microLED displays. Their approach to full color is to use red and green quantum dots to cover blue microLEDs. Internally, they develop quantum dot materials and photoresists to deposit the QDs. They are starting with 8” GaN-on-Silicon epi wafers which they wafer bond to the CMOS backplane before spin coating the QD/photoresist for photolithography.

Currently, the maximum brightness of the full-color display is 850K nits (no white point specified) with a target of reaching 1M nits in 2026. When integrated into their light engine, the company says they can deliver about 1 lumen with 100% DCI-P3 coverage. Resolution is 320×240.

The monochrome green microLED panel can deliver 7 million nits or 10 lumens out of the engine. They also showed monochrome red panel with QD conversion with 2M nits. A new product was a 0.6” panel.

Current displays are based on a 4-micron microLED, but the next generation will move to a 2.5-micron pixel pitch. Current production comes from their experimental line, but they plan to have a new fab by the end of the year in China.

The company showed their devices integrated into several AR glasses with diffractive waveguides partners (Zeiss, Optiark, Meta-Bounds and Raypaitech). Meta-Bounds won a CERS Innovation award in 2026 by showing AI smart glasses with the Raysolve full-color engine and a polymer waveguide. Raypaitech is developing geometric reflective waveguides. Optoark is developing waveguides that use one engine to drive two images for binocular glasses.

The company is also developing larger panels to support the MR market and microLEDs to support the optical interconnect market.
