E-ink technology has proven itself useful in many applications Since its inception in 1997 – From Digital whiteboard Per Laptop display, Even Personal belongings. At CES 2022, that technology finally entered the automotive industry as BMW unveiled the exterior of an e-ink car that could change color depending on weather and traffic conditions or just the driver’s mood.

In answer to your first question, no, this futuristic feature is not ready for production despite appearing on the show in a live demonstration vehicle dubbed BMW iX Flow featuring E Inc.

The electrophoretic coloring material itself is applied as a car body wrap but it works like an e-ink display on your Kindle. The packaging is embedded with millions of microcapsules, each containing a negatively charged white pigment and a positively charged-black pigment. Depending on the setting, applying an electric charge to the component will cause either white or black pigment to rise to the top of the microcapsule, which will instantly change the color of the car.

Although the current iteration can only switch between one pair of colors, the palette can eventually be expanded to display different shades of a rainbow value. “It gives drivers the freedom to express different aspects of their personality, or even to express the joy of their change, and to redefine it every time they get in their car,” said Stella Clark, Head Inc., Project Head, BMW IX Flow. Said in a prepared statement. “Like a status ad on a fashion or social media channel, the vehicle then becomes an expression of different moods and situations of daily life.”

E-ink external displays may also be effective in more practical applications such as changing the color depending on the weather to increase the battery life (and therefore range) of the car in cold weather or reducing the need for air conditioning in mild weather.
