E-paper technology is known as a display for static information. Although even playing videos on the EPDs has become possible, this application is still not in the foreground. There are definitely interesting possibilities to make the e-paper display move and animate the content. This technology is known as "Ink-In-Motion (IIM)".
The ability of the display to switch between white color and another main color (black, yellow, red, etc.) can be used to emphasize any area of the surface. This is the principle of this technology. The main part of the displays is the bistable E Ink film, which can change the color. It is not an active-matrix display, which means any graphic content cannot be represented by pixels, but it is rather a filled color area, a kind of segment. This E Ink film is flexible, bendable and can be cut. An impressive example of this can be seen in this E Ink video.
