Device for displaying a video image on a building

1. An element, in particular for a building, the element comprising:

two panes facing each other and forming double glazing; and

an electronic circuit suitable for displaying at least a portion of a video image by means of diodes and including units in the form of elongated bars arranged parallel to one another in a common plane and spaced apart from one another, each unit extending substantially between said two panes and comprising a support carrying said diodes on one of its sides that are spaced apart from one another along said elongated bars, said elongated bars being arranged such that a side of said elongated bars is in contact with and bearing against one of said two panes while a second side of said elongated bars is in contact with a surface of the other of said two panes;

wherein said elongated bars are arranged without any connection between them in a visible zone of said double glazing;

wherein said diodes are arranged on said elongated bars so that when said electronic circuit energizes said diodes, said at least a portion of said video image is displayed through at least one of said two panes and away from the building on which said two panes are mounted.

2. The element according to claim 1 , wherein said support of said elongated bar is a semi-transparent support.

3. The element according to claim 1 , wherein said elongated bar includes a layer of a protective material arranged on its side opposite to said support.

4. The element according to claim 1 , wherein said electronic circuit includes at least one connector that does not extend facing a visible zone of said two panes and that interconnects the various elongated bars that do extend facing said visible zone.

5. The element according to claim 1 , including a control module for said electronic circuit, which said control module is accessible from outside the element.

6. A display device comprising a plurality of elements according to claim 1 .

7. A wall of a building, in particular a facade, comprising at least one display device according to the claim 6 .

8. A building comprising at least one wall according to claim 7 .

9. A method of fabricating an element, in particular for a building, the method comprising the step of:

placing two panes and an electronic circuit including units in the form of elongated bars arranged parallel to one another, each unit including diodes and being suitable for displaying at least a portion of a video image by means of said diodes in such a manner that said two panes extend facing each other so as to form double glazing, and causing said elongated bars of said electronic circuit, which extends substantially between said two panes, to face a visible zone of said two panes;

wherein said elongated bars are arranged without any connection between them in said visible zone of said double glazing;

wherein said diodes are arranged on said elongated bars so that when said electronic circuit energizes said diodes, said at least a portion of said video image is displayed through at least one of said two panes and away from the building on which said two panes are mounted.

10. The method according to claim 9 , wherein each of said two panes bears against said elongated bars of said electronic circuit.

11. The method according to claim 9 , wherein said elongated bars of said electronic circuit are connected together by means of at least one connector and said at least one connector is placed in such a manner that it does not extend facing said visible zone.

12. The element according to claim 1 , wherein an at least partial gas vacuum exists between said two panes.
