Abstract
A user interface (200) for a portable electronic device (100) 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 (200) includes a segmented electro-optical device (407) configured to open and close shutters, thereby revealing and hiding the user actuation targets. The user interface includes a first polarizer (401) disposed above the segmented electro-optical device (407) and a colored reflective polarizer (405) disposed beneath the segmented electro-optical device. The colored reflective polarizer (405), which may include a colored dichroic polarizer (601) and a reflective polarizer (602), causes the user interface (200) to exhibit a predetermined color.
