Recently, Leiyu announced that it has successfully lit up a 0.39-inch single-chip full-color Micro-LED microdisplay chip, achieving a breakthrough in the product standardization process. The successful lighting of this chip is an important milestone for Micro-LED single-chip full-color technology from concept to product, and will bring revolutionary breakthroughs to the next generation of consumer AR glasses.

As we all know, the realization of single-chip full-color is one of the main bottlenecks currently restricting the application of Micro-LED.

Rayyu innovatively uses quantum dot color conversion technology, and uses standard photolithography processes to achieve a high-resolution, high-light-efficiency quantum dot color conversion film suitable for GaN blue Micro-LEDs. It excites red and green quantum dots with blue light, converts blue light into red light and green light, and realizes the three primary colors of RGB on a single chip, thereby realizing full-color chips. Through a unique optical isolation structure, it effectively reduces RGB color light crosstalk, thereby achieving higher contrast and color saturation. At the same time, relying on photolithographic quantum dot technology can effectively solve the light efficiency and brightness problems of native red light, qualitatively improving the overall brightness of the full-color chip.

For the application of quantum dot color conversion technology, the most critical indicator is the absorption efficiency of blue light. If the blue light absorption rate is too low, it will affect the purity of the color. The single-chip full-color Micro-LED micro-display technology independently developed by Leiyu is based on conventional film layer preparation conditions. Through optical design, material modification, and process optimization, it greatly improves the absorption efficiency and color stability of blue light, and achieves a high conversion efficiency quantum dot film layer with a lower mass ratio and a thinner film layer. In addition, this technology is compatible with semiconductor processes, allowing single-chip full-color Micro-LED microdisplays to be realized through standard and efficient semiconductor processes, thus laying a solid foundation for mass production.

Rayyu team released the world's first single-chip full-color Micro-LED microdisplay chip in Silicon Valley as early as 2019, taking the lead in achieving a breakthrough in the field of full-color Micro-LED microdisplay technology. The full-color process of this 0.39-inch chip will also be applied to the upcoming standardized full-color chip.

Dr. Zhuang Yongzhang, founder and CEO of Leiyu, said, "Rayu's single-chip full-color Micro-LEDThe microdisplay chip is specially designed for consumer-grade AR glasses that pursue lightweight, ultra-portable, high-brightness, and high-resolution, bringing the performance and excellent experience that users expect. The lighting of the 0.39-inch full-color Micro-LED microdisplay is just the first step for us, and it is also a key node. With the continuous expansion of the R&D team and the continuous improvement of product standardization processes, we are implementing smaller-size iterations, hoping that in the near future, AR glasses can be more than just an extended display for mobile phones, and become a true next-generation smart mobile platform. ”
