Abstract
Flat illuminating display device with light emitting means to illuminate a film for display of an image applied to a display area, wherein the light emitting means are embodied as at least one light coupling unit arranged laterally at a translucent film thus forming a light duct, wherein the light such fed into the adjacent edge area into the film is reflected by a reflective layer, which is applied on at least one side, to homogeneously spread within the film, wherein a reflection screen to obtain a light emission is provided opposite of the display area to create said display area.
Claims8
A flat illuminating display device, comprising light-emitting means for illumination of a film to display an image applied to a display area,
- wherein the light-emitting means are embodied as at least one light coupling unit laterally arranged at a translucent film forming a light duct,
- wherein the light fed into the film through the adjacent edge area is reflected in the film to homogeneously spread within the film and a reflection screen provided across the display area, to create a light emission,
- wherein the reflection screen represents a field leading to a diffuse reflection, and
- wherein the light located within the film is reflected and emitted diffusely from the film at the opposite side within the area of the display area.
A commercial aircraft comprising a large-volume fuselage having a passenger cabin, the cabin equipment of the passenger cabin comprising visible exterior surface areas for display purposes, the surface area are equipped with a flat illuminating display device, the display device comprising:
- light-emitting means for illumination of a film to display an image applied to a display area,
- wherein the light-emitting means are embodied as at least one light coupling unit laterally arranged at a translucent film forming a light duct,
- wherein the light fed into the film through the adjacent edge area is reflected in the film to homogeneously spread within the film, and a reflection screen provided across a display area to create a light emission,
- wherein the reflection screen represents a field leading to a diffuse reflection, and
- wherein the light located within the film is reflected and emitted diffusely from the film at the opposite side within the area of the display area.
