Abstract
A user interface () for a portable electronic device () is configured to transition from a first state to a second state to present a plurality of mode-based user actuation targets to a user. The user interface () includes a segmented electro-optical device () configured to open and close shutters, thereby revealing and hiding the user actuation targets. The user interface includes a first polarizer () disposed above the segmented electro-optical device () and a colored reflective polarizer () disposed beneath the segmented electro-optical device. The colored reflective polarizer (), which may include a colored dichroic polarizer () and a reflective polarizer (), causes the user interface () to exhibit a predetermined color.
