"Vantablack" absorbs an astonishing 99.965% of visible light, allowing only a minuscule amount to escape, pushing the boundaries of the darkest material ever created. When standing in front of it, shapes, contours, and details nearly disappear, evoking the sensation of gazing into an endless, unfathomable void—as staring directly into a black hole.

The electrochromic (EC) smart dimming sunroof featured in the Xiaomi YU7 Max boasts an exceptional light blocking rate of up to 99.85%. This seemingly minute difference has raised an interesting question: Can a 0.85% improvement really make a noticebale impact?

In July 2025, Ambilight marks its 8th anniversary. Over the past eight years, we have continuously advanced our core technologies, strengthened product capabilities, and accelerated innovation to help define the global electrochromic (EC) industry. We are grateful to every partner who has been part of this journey and look forward to building an "Infinite Future" together.

On June 26, Xiaomi launched the YU7, its first mid-size electric SUV. The high-end YU7 MAX model sets a new benchmark for intelligent mobility, coming standard with the new-generation electrochromic smart dimming sunroof developed by Ambilight, an industry leader in flexible electrochromic technologies.

We’re happy to share that Ambilight’s Electrochromic (EC) Smart Dimming Sunroof has been honored the Silver award at the un Design Award for its cutting-edge product design concept and high performance.
