Abstract

An electronic device may include a projection display that has a high transparency when the display is turned off. The high off-state transparency may create the appearance of the display being invisible in the off-state, which may be desirable in certain electronic devices. The projection display may include an adjustable diffuser, a spatial light modulator that projects images onto the adjustable diffuser, a mirror that reflects the images from the spatial light modulator to the adjustable diffuser, and a light source that provides light to the spatial light modulator. The projection display may also include an adjustable opacity layer that is controlled based on detected ambient light levels. The projection display may also include an adjustable reflectivity layer. The adjustable diffuser and/or light source may be pixelated to increase contrast in the projection display.
