Window element

1. A window element comprising

at least one sheet element and at least one surface intended for the reproduction of images,

wherein the sheet element comprises at least one projector-independent image-generating display,

the image-generating display is an organic light emitting diode display,

reproduction of image elements on the sheet element is carried out in a first state with the image-generating display switched on, and

the sheet element of the window element is transparent in a second state with the image-generating display in a switched-off state,

an illuminating device with at least one light-emitting means to radiate light suitably into an edge of the sheet element,

wherein the sheet element scatters light in such a way that the light of the light-emitting means is deflected substantially perpendicular to the irradiation direction from the at least one light-emitting means and is output via the surface of the sheet element, at least toward one side.

2. The window element as claimed in claim 1 , wherein the display is an intrinsically flexible flat display applied to the sheet element or accommodated in the sheet element.

3. The window element as claimed in claim 1 , wherein the window element is a composite element having a plurality of sheet elements in the composite.

4. The window element as claimed in claim 1 , wherein the window element comprises at least one composite element comprising a plurality of sheet elements, of which at least one is a glass plate or plastic glass plate, into which light is radiated at an end via light-emitting means and of which at least one sheet element is a flat display.

5. The window element as claimed in claim 1 , wherein the window element comprises at least one composite element with at least two largely translucent sheet elements, between which a flat display is embedded.

6. The window element as claimed in claim 1 , wherein the window element comprises at least one frame construction which encloses a sheet element or a plurality of sheet elements arranged in a composite at one or more edges or peripherally at the edge.

7. The window element as claimed in claim 1 , wherein a frame construction largely covers a light-emitting means radiating into at least one sheet element at an end, as viewed in the direction of the normal to the surface of the sheet elements.

8. The window element as claimed in claim 1 , wherein the window element further comprises control devices for the operation of the display and/or for the control of a light-emitting means, in particular periodic and/or color control of the lightemitting means.

9. The window element as claimed in claim 1 , wherein the display is applied in the form of a flexible film flat display to at least one sheet element which is translucent and outputs light when the light-imaging means is switched on, and applied by adhesive bonding.

10. The window element as claimed in claim 1 , wherein the active display in each case comprises one or more image-generating layers which are applied to a carrier layer, in particular sprayed on, vapor deposited, printed on or applied by other coating processes.

11. The window element as claimed in claim 10 , wherein the carrier layer is a separate carrier layer or a layer that is already present, a glass layer of the window element.

12. The window element as claimed in claim 1 , wherein the window element comprises at least one protective layer for covering the image-generating layer.

13. The window element as claimed in claim 1 , wherein the window element comprises at least one intermediate layer which is switched over from a transparent state into an opaque or reflective state.

14. The window element as claimed in claim 1 , wherein the window element comprises at least two image generating layers and at least one transparent intermediate layer which is arranged between them and is switched over into an opaque or reflective state.

15. The window element as claimed in claim 1 , wherein the window element comprises at least one image generating layer and at least two transparent intermediate layers which are arranged on both sides of the image generating layer and is switched over into an opaque or reflective state.

16. The window element as claimed in claim 1 , wherein a carrier layer used for an image-generating layer is a glass layer or acrylic glass layer which has an additional functional coating, a sunshade coating and/or coloration.

17. A facade, wall, ceiling, roof, dividing wall, staircase, door, elevator, railings, escalator or traveling pavement of a building, characterized in that this comprises at least one window element as claimed in claim 1 .

18. A piece of furniture, municipal furniture or garden furniture, comprising at least one window element as claimed in claim 1 .
