BMW iX Flow (2022): display film turns the iX into a chameleon

E-book readers use a special display technology, which requires very little electricity. BMW is now making use of this technology for a completely new purpose: The Munich-based company does not want to develop a new display, but rather transform a BMW iX into a driving chameleon. the BMW iX Flow namely can change its color if necessary.

Together with the company “E-Ink”, BMW gives the iX Flow the ability to change its color to match the external conditions. More than 20 square meters of the special film were cut in the shape of triangles and glued to the surface of the iX.

The many small triangles were necessary to bring the rather rigid display material onto the BMW.

The polygonal shapes created by the laser cutter were necessary because the display film is not as flexible as classic car body film. Nice side effect: when the colors change, the programmed ones see Color gradients because of the many triangles spectacular out.

Many possibilities, especially in the interior

But technology also offers new possibilities in surface design. The foils from E-Ink can also be equipped with other colors and thus used as a design element. One The technology is ready for series production in its current form seems unlikely, but BMW would like to promote the approach.
