“Apple’s venture into mixed reality, albeit remarkable, is tethered to Micro-OLED displays. These come with their baggage—like soaring costs, compromised brightness, and longevity concerns,” shared Dr. Eddy Hsu, the co-founder of the influential Rayleigh Vision with over 20-year experience in Micro-LED technologies.
The microdisplay research team, led by Professor Jr-Hau HE at City University of Hong Kong and its spin-off company Rayleigh Vision, has made significant advancements in Micro-LED technologies to overcome the current limitations. Their newly announced two-layer Micro-LED array showing a cutting-edge stacking technology, to craft dual-layer units where each layer can modulate colors independently. The team’s stacking processes have gained initial validation and are on track to cultivate an RGB full-color Micro-LED. This advancement is expected to double the pixel density of current planar devices or more. This product boasts high contrast, high brightness, wide color gamut, high efficiency, low power consumption, and long lifetime, making it suitable for a wide range of applications in entertainment, consumer electronics, and professional industries.
With hubs in California, Hong Kong, and Taiwan, it’s Rayleigh Vision’s approach to Micro-LEDs that has industry insiders talking. The team has launched several products, such as the 0.55” full-color Micro-LED microdisplay and an impressive 0.38” monochromatic Micro-LED microdisplay boasting a pixel density of 3780 ppi. Moreover, by achieving a technological feat in successfully cultivating 2.5 μm Micro-LED pixels and building a pixel array with the pixel density exceeding 10,000 ppi, Rayleigh Vision become one of the select teams in the market capable of harnessing this cutting-edge technology.
Dr. He emphasized, “While stacked Micro-LED technology holds immense potential, it also faces several challenges, including precise alignment, repair difficulties, heat dissipation, as well as…
