IMAGE DISPLAY APPARATUS, AND DISGUISING DEVICE

摘要

An image display apparatus (100) comprises: -a display device (104) for displaying an image by emission of display light (210) in a first direction; -a scattering layer (902) disposed in front of the display device (104), for scattering at least a portion of ambient light (208); -a transparent plate-shaped light source (950), arranged parallel to the scattering layer (902) and beingoptically coupled to the scattering layer (902). The plate-shaped light source (950) may be a passive light source, in which case at least one light source (967) is arranged along an edge of the plate-shaped light source (950). When the display device (104) is ON, the scattering layer (902) and the plate- shaped light source (950) are transparent. When the display device (104) is OFF, the scattering layer (902) is scattering and the plate-shaped light source (950) is ON.
