BMW’s E Ink can change car color in a snap

“It’s definitely a prototype,” Clark said at a press conference in Munich last year. [regarding] Technical specs, we’re heading in that direction. I can say that for sure. “

Clark, an engineer who had previously worked on dashboard technology, first applied electronic ink to solve the glare problem behind the steering wheel.

The first feature was to display information in bright sunlight, keeping the steering wheel and dashboard buttons visible at all times.

Clark’s team then applied E Ink to the car’s exterior to display information and warn drivers about disabled vehicles.

The i Vision Dee at CES had a customizable exterior film that could display up to 32 colors and almost endless patterns. The surface is divided into 240 segments that can be individually controlled, allowing a series of patterns to be generated in seconds.

Engineers have adapted E Ink technology to program curved surfaces and animations, so i Vision Dee responds to voice commands by displaying facial expressions, projecting driver avatars onto windows, and displaying information such as the vehicle’s charging status. was able to provide

Automotive applications for electronic ink go beyond aesthetics. Chameleon-like technology allows emergency vehicles such as ambulances to be more visible, even in daylight.

“When the whole car flashes red and white, it’s much more noticeable than just flashing lights,” Clark said.

This technology can also increase energy efficiency. Adjusting to lighter colors on hot days or switching to darker skin on cloudy days can reduce the use of your car’s air conditioning.

Unlike displays and projectors, E Ink technology consumes power only when switching colors.

“You don’t need energy to hold color,” Clark said. “Even if you unplug it, it stays that color.”
