On April 25, Micro LED company Hongshi Intelligent held a media briefing to introduce the company's breakthroughs in key technologies, especially its progress in single-chip full-color Micro LED technology.
Currently, Hongshi Intelligent has successfully lit up a 0.12-inch single-panel full-color sample with a white light brightness of 1.2 million nits. The company plans to increase this indicator to 2 million nits by the end of the year and continue to optimize the light efficiency.
This product utilizes the company's independently developed Hybrid Stack Structure and quantum dot color conversion technology to achieve the integration of blue-green epitaxial wafers and the precise rendering of red light. Through unique process design, Hongshi Intelligent has expanded the red light-emitting area, thereby improving luminous efficiency and brightness.
Hongshi Intelligent's hybrid stacking structure simplifies the production process, reduces process errors, lowers production costs, and promotes the development of Micro LED technology. Despite the challenges of cost and yield in monolithic full-color technology, the company is confident in its future development and plans to deploy color production in the Moganshan project, with mass production and commissioning expected to begin in the second half of next year.
Since its establishment in 2017, Hongshi Intelligent has been focusing on the research and development and manufacturing of Micro LED microdisplay chips. In 2020, Hongshi Intelligent launched a technology transformation and industrial upgrading, established a cooperation with the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences, and assembled a research and development team of nearly 100 people in Shenzhen, Shanghai, Suzhou and other places.
In terms of products, Hongshi Intelligent's Aurora series includes three models: 0.12-inch, 0.61-inch, and 0.69-inch. Among them, the Aurora A6 is the world's brightest 0.12-inch Micro LED microdisplay chip, with a resolution of 640x480 and a brightness of up to 8 million nits. It also offers multiple interface versions, such as MIPI, SPI, and QSPI.
