Abstract

An organic light emitting diode display includes a stretchable substrate, a plurality of pixel forming plates, first and second pixels, and a cut-out groove. The pixel forming plates are on the substrate and spaced apart from each other. The first and second pixels are on respective first and second pixel forming plates of the plurality of the pixel forming plates adjacent in a first direction. The first and second pixel forming plates are connected by a first bridge. The cut-out groove are in the first and second pixel forming plates and adjacent to an area connected to the first bridge.

First claim

What is claimed is:

1. An organic light emitting diode display, comprising:
a stretchable substrate;
a plurality of pixel forming plates on the substrate and spaced apart from each other; and
first and second pixels on respective first and second pixel forming plates of the plurality of pixel forming plates adjacent in a first direction, the first and second pixel forming plates connected by a first bridge,
wherein a portion of each of the first and second pixel forming plates, which is adjacent to the first bridge, has a side bent towards a second direction perpendicular to the first direction.

2. The display as claimed in claim 1 , wherein each of the first pixels and the second pixels includes a plurality of subpixels.

3. The display as claimed in claim 2 , wherein at least one of the plurality of subpixels has a rhombus shape.

4. The display as claimed in claim 1 , wherein each of the first pixels and the second pixels includes a plurality of subpixels having different sizes.

5. The display as claimed in claim 1 , wherein each of the first pixels and the second pixels includes three subpixels, two of which have a same size and the other of which has a size different from the two subpixels.

6. The display as claimed in claim 5 , wherein the two subpixels have a square shape and the other subpixel has a rectangular shape.

7. The display as claimed in claim 1 , wherein the first bridge has a predetermined width.

8. The display as claimed in claim 1 , wherein the first bridge is upwardly or downwardly curved along the second direction.

9. The display as claimed in claim 1 , wherein the first pixel forming plate includes:
a first main supporting plate;
a first wing plate on one lateral surface of the first main supporting plate, wherein one side end portion of the first wing plate is connected to the first bridge;
a second wing plate on another lateral surface of the first main supporting plate and adjacent to the one side end portion of the first wing plate; and
a first cut-out groove between one side end portion of the second wing plate and the first bridge.

10. The display as claimed in claim 9 , wherein the second pixel forming plate includes:
a second main supporting plate;
a third wing plate on one lateral surface of the second main supporting plate to face the first wing plate of the first pixel forming plate, one side end portion of the third wing plate connected to the first bridge;
a fourth wing plate on another lateral surface of the second main supporting plate and adjacent to the one side end portion of the third wing plate; and
a second cut-out groove between one side end portion of the fourth wing plate and the first bridge.

11. The display as claimed in claim 1 , further comprising:
a base layer including:
a third pixel forming plate adjacent to the first pixel forming plate in the second direction;
a third pixel on the third pixel forming plate; and
a second bridge connecting the first and third pixel forming plates.

12. The display as claimed in claim 11 , further comprising:
a plurality of first to third wires on the first pixel forming plate and connected to the first pixel, wherein the first wires are connected to a second pixel of the second pixel forming plate through an upper side of the first bridge.

13. The display as claimed in claim 12 , wherein the first wires extend in a length direction of the first bridge and are disposed in an outer side of a center line of the first bridge passing through a center of the first bridge.

14. The display as claimed in claim 12 , further comprising:
a plurality of dummy wires on the first bridge and disposed above or below the first wires to overlap a portion of the first wires, wherein strain on the dummy wires is greater than that on the first wires.

15. The display as claimed in claim 14 , wherein the dummy wires extend in a length direction of the first bridge and are disposed in an inner side of a center line of the first bridge passing through a center of the first bridge.

16. The display as claimed in claim 15 , wherein lengths of the dummy wires decrease from an inner side of the first bridge toward an outer side thereof.

17. The display as claimed in claim 12 , further comprising:
a sensing thin film transistor on the respective pixel forming plates and connected to at least one of the first to third wires to measure strain on the at least one of the first to third wires.

18. The display as claimed in claim 12 , wherein the first wires include a plurality of gate lines.

19. The display as claimed in claim 12 , wherein the second wires include a plurality of data lines and the third wires include a plurality of driving voltage lines.

20. The display as claimed in claim 1 , wherein each of the pixel forming plates has substantially a polygonal shape.
