Adjustable support structure for display tile

1. Support substructures each for fastening a display tile to a support structure of a tiled display, adjacent display tiles in the tiled display being separated by a nominal seam, the support substructures comprising:

a support substructure;

a first mechanism that links the support substructure to the support structure, wherein the first mechanism is configured to allow movements of each display tile in a plane parallel to a nominal plane (XY) of the tiled display to form a gap between adjacent display tiles obtained by moving one or more display tiles from a first position (P 1 ) to a second position (P 2 ); and

a second mechanism configured to fix the position of the first support substructure in the second position,

wherein the gap is larger than the nominal seam,

wherein the display tile has one or more contact elements configured to exert a force on an adjacent display tile, and

wherein the contact elements self-align the display tile with the adjacent display tile.

2. The support substructures according to claim 1 , wherein the first mechanism is configured to be driven by a motor or a hand crank or a key.

3. The support substructures according to claim 1 , wherein the first mechanism includes means to transform a rotary movement into a translation of the support sub structure.

4. The support substructures according to claim 1 , wherein the first mechanism comprises a quadrant gear and a pin, the quadrant gear configured to exert a force on the support substructure by the intermediary of the pin.

5. The support substructures according to claim 1 , wherein the first mechanism comprises guiding means configured to control the direction and/or amplitude of the movement of the support substructure.

6. The support substructures according to claim 1 , further comprising a release mechanism.

7. The support substructures according to claim 1 , wherein the second mechanism comprises a lever or hammer that can take two positions and a pin fastened to the support substructure: wherein in a first position, the pin is configured to be able to move freely; and in a second position, the hammer prevents free movement of the pin.

8. The support substructures according to claim 1 , wherein the display tile is fastened or mated to the support substructure by the intermediary of another support substructure, the another support substructure comprising a mechanism for moving the display tile outside of the display plane (XY).

9. A tiled display comprising support substructures according to claim 1 .

10. The tiled display according to claim 9 , wherein the support substructures are fastened to the support structure by the intermediary of an additional support substructure which is fastened to the support structure by means of an alignment mechanism, the alignment mechanism being for aligning adjacent display tiles.

11. A method for manipulating display tiles each display tile being fastened to a support structure of a tiled display using a support substructure, adjacent display tiles in the tiled display being separated by a nominal seam, the method comprising:

mechanically linking the support substructure to the support structure;

moving one or more display tiles in a first movement in a plane parallel to a nominal plane (XY) of the tiled display to form a gap between adjacent display tiles obtained by moving one or more display tiles from a first position (P 1 ) to a second position (P 2 ) and fixing the position of the support substructure in the second position, wherein the gap is larger than the nominal seam; and

self-aligning the display tile using one or more contact elements for exerting a force on an adjacent display tile.

12. The method according to claim 11 , wherein the first movement is driven by a motor or a hand crank or a key.

13. The method according to claim 11 wherein the first movement includes transforming a rotary movement into a translation of the support sub structure.

14. The method according to claim 11 , further comprising guiding the first movement to control the direction and/or amplitude of the first movement.

15. The method according to claim 11 , further comprising fastening or mating the display tile to the support substructure by the intermediary of an another support substructure, further comprising a further movement for moving the display tile outside of the display plane (XY).

16. A support substructure configured to fasten a tiled display having an array of display tiles, to a support structure, the support substructure comprising:

an alignment mechanism configured to fasten the support substructure to the support structure, the alignment mechanism being configured to be adjustable to align adjacent display tiles with respect to each other, further comprising a first fastening bolt perpendicular to the support structure,

the support substructure further comprising means for displacement of the alignment mechanism in the direction parallel to the axis of the first fastening bolt.

17. A method of manipulating a support substructure that is used to fasten a tiled display having an array of display tiles, to a support structure, the method comprising:

fastening the support substructure to the support structure by means of an alignment mechanism, and

aligning adjacent display tiles with respect to each other with the alignment mechanism, wherein the alignment mechanism is adjustable,

wherein the alignment mechanism has a first fastening bolt perpendicular to the support structure, and

the method comprising displacing the alignment mechanism in a direction parallel to the axis of the first fastening bolt.
