Korea's Raontech announced that it has signed an MoU with SN Display to co-develop perovskite-based next-generation AR/VR displays. The two companies are already conducting preliminary research in which SN Display's perovskite technology is applied to Raontech's microLED microdisplay samples, in order to verify the performance improvements and potential applications of next-generation microdisplays.

Perovskite materials can achieve high color purity and a wide color gamut even in very small pixels, which makes them a promising color conversion material for AR/VR microdisplays. Perovskites offer high color conversion efficiency even in layers thinner than 0.5 micron, and they can be patterned using semiconductor processes - and so are seen as an alternative that could overcome the limitations of current quantum dot (QD) color conversion materials.

Raontech says that depending on the sample evaluation results and the technical progress, the two companies may jointly develop microdisplay prototypes, or expand their collaboration to next-generation display solutions for AR/VR applications.

The two companies will also test SN Display's perovskite QDs on Raontech's OLED microdisplay samples.

SN Display is a faculty-founded startup of Professor Tae-Woo Lee of Seoul National University, established in 2020. The company offers perovskite nanocrystals, resins and down-conversion films, and also develops perovskite nanocrystal arrays for high-resolution (over 3,000 PPI) AR/VR displays. Earlier this year, Prof. Lee's team and SN Display reported a hierarchical-shell perovskite nanocrystal platform with near-unity efficiency and improved stability, which is compatible with inkjet printing and photolithography at pixel densities above 3,500 PPI. Raontech develops microdisplays for AR/VR devices, and in January it was part of a team that developed a 1,700 PPI monolithic red microLED microdisplay, together with KAIST, Inha University and QSI.

Perovskites are attracting growing interest as a color conversion material for microLED microdisplays. In March 2026, CEA-Leti researchers demonstrated thin-film perovskite color conversion layers that absorb 90% of the blue light at thicknesses of only 360-500 nm, compared to the 3-10 micron required for QD layers. In China, Yicai Core Light is developing microLED microdisplays based on perovskite QD color conversion.
