In a groundbreaking development, WiMi Hologram Cloud Inc. has unveiled a quantum dot micro-scale component for AR/VR displays, marking a significant leap forward for the industry. This innovative technology is garnering attention due to its exceptional features, including ultra-fast response time, high resolution, high brightness, and superior outdoor performance. WiMi’s cutting-edge solution addresses several critical technological challenges and paves the way for advancements in AR/VR experiences.
One of the key breakthroughs achieved by WiMi’s research team is the successful resolution of the surface buckling issue in display fabrication. Traditionally, highly efficient bandgap materials such as gallium nitride (GaN) are used for display production, typically placed on a sapphire or silicon wafer. However, the mismatch between these materials often leads to severe buckling on the wafer surface, making fabrication of small pixels particularly challenging. To tackle this problem, WiMi developed a remarkably thin and adhesive bonding alloy that effectively immobilizes GaN epitaxial layers. Additionally, they employed a pre-patterned bonding technique to enhance alignment between the GaN layer and the new silicon substrate. This breakthrough not only resolves fabrication difficulties but also ensures the overall quality and performance of the displays.
Another critical challenge addressed by WiMi involves color conversion for high-quality images. To achieve vibrant and accurate colors in AR/VR applications, a balance must be struck between color accuracy and efficiency. WiMi’s solution introduces quantum dots (QDs) as a key material for the color conversion layer. These nanocrystals can generate specific colors of light when excited at different wavelengths, providing high spectral purity and broad color gamut. By integrating QDs into displays, WiMi achieves exceptional color performance, resulting in vivid and lifelike image reproduction.
These breakthroughs propel WiMi’s quantum dot micro-scale display components to new heights of feasibility and application potential. With improved surface buckling control and high-quality color conversion, this technology boasts impressive features such as ultra-fast response time, high resolution, high brightness, and accurate color representation. These advancements are poised to revolutionize the AR/VR field, delivering an enhanced visual experience to users.
