Ambilight is pioneering advancements in electrochromic (EC) technology, setting new industry standards in smart dimming solutions. As the world’s only company capable of mass-producing black EC dimming products, our first-generation solution launched in 2024 has already been adopted by leading vehicle models, including the NIO ET5T and EC6.
Now, we’re taking innovation even further. Our next-generation black EC smart dimming product delivers major improvements in both color purity and dimming contrast achieving two breakthrough advancements within just one year.
Dramatically Improved Dimming Range
Our next-generation black EC smart dimming product pushes the limits of visual clarity and privacy. While the first generation offered basic transitions between light and dark, the new version achieves a far wider dimming range—brighter in the light state and darker in the dark—resulting in stronger visual contrast and effectively eliminating glare, even under intense sunlight.
● Bright Mode: Nearly fully transparent, it allows abundant natural light into the cabin, creating a bright, open atmosphere—far superior to conventional privacy films.
● Dark Mode: Blocks over 99.65% of light, significantly outperforming traditional automotive films (typically limited to 95%). This ensures complete privacy, even in low-light spaces like garages, where internal lights often compromise standard films.
Delivering this performance relies on cutting-edge wide-range EC materials and a highly transparent ion storage layer (IS layer)—a virtually invisible powerhouse capable of holding large electric charges, much like an optical-grade battery.
Pure Black Color Achieved Across Full Spectrum
True black absorbs all visible wavelengths (380–780nm). To achieve this, Ambilight solved a key industry challenge by enabling uniform absorption across the full spectrum—including the difficult 476–630nm range—while maintaining long-term reliability and stability.
This achievement mirrors challenges seen in OLED blue light development, where high-energy states cause instability, delayed response, and uneven coloring. Ambilight has now overcome these hurdles in EC material design.
Looking Ahead
These advancements are the result of extensive R&D efforts, reflecting deep innovation in materials, processes, and system design. With this new-generation EC smart dimming technology, Ambilight is setting a new benchmark in the industry.
Going forward, the company will continue to lead innovation in EC technology, unlocking broader applications in automotive, smart buildings, consumer electronics, and beyond—bringing smarter, more comfortable experiences to everyday life.
