Abstract: A backlit partially reflective mirror may be used to form a logo or other structure in an electronic device. The electronic device may have a housing. The housing may have a wall with one or more openings configured to receive one or more corresponding logo-shaped portions of the partially reflective mirror. The partially reflective mirror may be illuminated using backlight illumination from a backlight that is overlapped by the partially reflective mirror. The partially reflective mirror may be formed from one or more protruding structures on a common substrate. One or more thin-film layers may be configured to provide the partially reflective mirror with desired visible light reflection spectrum, a desired visible light transmission spectrum, and a desired visible light absorption spectrum. The reflectivity of the mirror may be configure so that the mirror serves as a one-way mirror for the logo or other structure.
