After the matrix Micro LED car light chip was successfully lit in October 2023, on January 25, 2024, the company made another major breakthrough in the matrix Micro LED car light chip. The brightness of the chip reached a new level and reached the best international level.
This improvement in chip brightness is due to the continuous in-depth optimization and consolidation of the company's core technology, as well as the application of innovative patented technologies. Among them, chemical stripping technology is used to its extreme. It can not only transfer a large amount of GaN pixels to the CMOS driver chip without damage, but also make the light-emitting surface of the pixels evenly roughen into a pyramidal microstructure, like individual particles. Covered with gems, they shine brightly, which greatly improves the reliability and brightness of the pixels.

In addition, the patented metal air bridge connection technology is applied and demonstrated for the first time in this product. Due to the connection of the metal air bridge, 40 μm pixels can be isolated and electrically connected, thus producing high-definition video. Compared with chips produced by laser peeling, the contrast and high-definition effects are obvious, which is at the leading level in the world.
The first year of digital car headlights has begun, and various manufacturers in the industry chain are also working hard on research and development, striving to gain first-mover advantages and lead the trend. As the core link in the industrial chain, Xinyuanji is no exception and is working hard to apply its products as soon as possible to improve vehicle driving safety.
