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.

Abstract: An illuminated metal keycap having a legend diffuser material that may diffuse light through a legend opened in a background layer. The background layer may be opaque and the legend may be transparent. The metal keycap is adhered to a scissor mechanism positioned above electrical switch circuitry. Included within, below, or adjacent to the scissor mechanism may be one or more light sources positioned to emit light through the metal keycap, around the perimeter of the metal keycap, and/or through the background layer.
