Abstract
An electronic device includes a housing, an electronic display viewable from a front side of the electronic device, an optical shuttering layer substantially parallel to the front side, and a color changing layer positioned over at least a portion of the shuttering layer. A driver controls transitions of the shuttering layer between a transparent clear state and an opaque state and also transitions of the color changing layer between a transparent clear state and a colored state. Depending on driver control, the appearance of the electronic device can change from an opaque color (solid color or with graphic design elements), to a translucent color (solid color or with graphic design elements) possibly with an underlying electronic display somewhat visible, to a transparent color with an underlying electronic display clearly visible.
