BMW E Ink allows vehicle owners to change the color of a vehicle. ยท E Ink is not paint; it’s a wrap composed of numerous ePaper panels.
Users may now be able to customize vehicle exteriors with minimal hassle at the touch of a button, when prompted by aesthetic preferences, environmental conditions, or a host of other functional purposes.
By making use of electrophoretic coloring (developed by E Ink for use in e-reader displays), different color pigments are brought to the forefront.
Electrophoresis is a process for separating charged molecules based on their movement through a fluid under the influence of an applied electric field.
When stimulated by an electric field, the surface of each microcapsule is flooded by one of the pigments as per the given setting, to impart color to the body – much like an electronic paper display (EPD).
