"In a MIRASOL display, a flexible thin-film mirror is fabricated on a transparent substrate, leaving an air gap of a few hundred nanometers between the thin film and the substrate such that when ambient light enters this cavity and reflects off the thin-film mirror, it interferes with itself, producing a resonant color determined by the height of the cavity. A MIRASOL display produces iridescent color, similar to what you would observe in a butterfly’s wings. Depending on the electric field applied between the substrate and the thin film, the film can be positioned in one of two states. Because MIRASOL displays are bistable, they don’t require a refresh until the image is changed. As a result, they consume very little power, providing extended battery life for the user."
