Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have a pixel array that produces light associated with images. The display system may also have a linear polarizer through which light from the pixel array passes and a quarter wave plate through which the light passes after passing through the quarter wave plate. The optical system may be a catadioptric optical system having one or more lens elements. The lens elements may include a plano-convex lens and a plano-concave lens. A partially reflective mirror may be formed on a convex surface of the plano-convex lens. A reflective polarizer may be formed on the planar surface of the plano-convex lens or the concave surface of the plano-concave lens. An additional quarter wave plate may be located between the reflective polarizer and the partially reflective mirror.

Abstract: An electronic device may be provided with a display. The display may have a display cover layer. The display may have an active area with pixels and an inactive area with dummy pixels. The dummy pixels may have structures that are optically matched to the pixels so that the dummy pixels and pixels have similar visual appearances when the display is off. An optical window may be formed in the inactive area. A light-based component such as an ambient light sensor, proximity sensor, or image sensor may be mounted in the electronic device in alignment with the optical window. A polarizer layer may overlap the active and inactive areas of the display. An opening in the polarizer or a bleached unpolarized portion of the polarizer may be aligned with the optical window.
