Introduction
On January 25, ChipFoundation announced a significant breakthrough in matrix Micro LED automotive lighting chips.
Enhanced Brightness through Innovative Technologies
The company reported that the enhancement of brightness in its Micro LED automotive lighting chips is attributed to the optimization of core technologies and the application of innovative patented techniques. The chemical peeling technology not only facilitates the non-destructive mass transfer of GaN pixel points onto CMOS driving chips but also allows for the uniform texturing of the pixel light-emitting surface into a pyramidal microstructure.
Application of Metal Air Bridge Connection
Additionally, the patented metal air bridge connection technology is showcased for the first time in this product. The connection via the metal air bridge enables the independent isolation of 40μm pixel points while maintaining electrical connectivity, resulting in high contrast and clarity. This method yields significantly better results compared to chips produced using laser peeling techniques.
Embracing the Era of Digital Automotive Lighting
ChipFoundation stated that the era of digital automotive lighting has begun, with manufacturers across the industry ramping up research and development efforts to secure a competitive advantage. As a critical component of the supply chain, the company aims to expedite the application of its products to enhance vehicle safety.
Diverse Applications of Digital Automotive Lighting
The digital automotive lighting system plays various roles in multiple application scenarios, including distance alerts, lane change signals, narrow road width assistance, corner lighting, tunnel illumination, welcome lighting, weather and music projections, autonomous driving notifications, lane safety guidance, and pedestrian yielding signals.
Company Background
Founded in 2014, ChipFoundation specializes in the independent research, design, and production of sapphire-based GaN high-end thin film structure chips and Mini/Micro LED chips based on third-generation semiconductor gallium nitride (GaN) materials.
Achievements in Micro LED Technology
ChipFoundation has made considerable advancements in Micro LED technology: in 2022, it achieved full-screen lighting with a 5μm Micro LED chip array, and in 2023, it realized video display capabilities with a 0.39-inch monochrome Micro LED display, marking breakthroughs in Micro LED mass transfer technology and developing wafer-level stamping mass transfer processes with zero deviation in chip positioning.
