Abstract

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the display includes a stretchable substrate, a thin film transistor (TFT) formed over the stretchable substrate and including a plurality of electrodes, an OLED electrically connected to the TFT and including a plurality of electrodes, and a plurality of interconnection lines connected to the electrodes of the OLED and the TFT. At least one of the interconnection lines is configured to move in a stretching direction and rotate an electrode selected from the electrodes of the OLED and the TFT connected to the at least one interconnection line.

First claim

What is claimed is:

1. An organic light-emitting diode (OLED) display comprising:
a stretchable substrate;
a thin film transistor (TFT) formed over the stretchable substrate and including a plurality of electrodes;
an OLED electrically connected to the TFT and including a plurality of electrodes; and
a plurality of interconnection lines connected to the electrodes of the OLED and the TFT,
wherein at least one of the interconnection lines is movable in a stretching direction, and wherein a selected one of the OLED electrodes and the TFT electrodes is rotatable.

2. The OLED display of claim 1 , wherein the at least one interconnection line is connected to a corner portion of the selected electrode.

3. The OLED display of claim 2 , wherein the least one interconnection line comprises a bent portion configured to be straightened when the stretchable substrate is stretched.

4. The OLED display of claim 2 , wherein the TFT comprises an active layer, a gate electrode, a source electrode, and a drain electrode, and wherein the OLED comprises a pixel electrode, an emission layer, and an opposite electrode.

5. The OLED display of claim 4 , wherein the selected electrode includes the pixel electrode.

6. The OLED display of claim 4 , wherein the selected electrode includes the gate electrode.

7. The OLED display of claim 4 , wherein the selected electrode includes the source electrode.

8. The OLED display of claim 4 , wherein the selected electrode includes the drain electrode.

9. The OLED display of claim 4 , wherein the selected electrode includes the opposite electrode.

10. The OLED display of claim 2 , wherein the selected electrode has four corners, and wherein the interconnection lines are respectively connected to the four corners.

11. The OLED display of claim 1 , wherein two or more of the interconnection lines are movable in the stretching direction.

12. An organic light-emitting diode (OLED) display comprising:
an elastic substrate;
an OLED formed over the substrate and including a plurality of electrodes; and
a plurality of first interconnection lines each having a plurality of bent portions and a plurality of substantially straight portions connected to the bent portions, wherein one of the bent portions is connected to a first electrode selected from the OLED electrodes, and wherein one end of the interconnection lines is movable away from the first selected electrode so as to rotate the first selected electrode.

13. The OLED display of claim 12 , wherein the substantially straight portions are substantially parallel to each other.

14. The OLED display of claim 13 , further comprising:
a thin film transistor (TFT) formed over the OLED and including a plurality of electrodes; and
a plurality of second interconnection lines each having a plurality of bent portions and a plurality of substantially straight portions connected to the bent portions, wherein one of the bent portions is connected to a second electrode selected from the TFT electrodes, and wherein one end of the second interconnection lines is configured to be pulled away from the second selected electrode so as to rotate the second selected electrode.

15. The OLED display of claim 14 , wherein the substantially straight portions are substantially parallel to each other.

16. The OLED display of claim 15 , wherein each of the first and second interconnection lines is respectively connected to corner portions of the first and second electrodes.

17. The OLED display of claim 15 , wherein the bent portions are configured to be straightened when the substrate is stretched.

18. The OLED display of claim 15 , wherein the first selected electrode includes one of a pixel electrode and an opposite electrode.

19. The OLED display of claim 15 , wherein the second selected electrode includes one of a gate electrode, a source electrode, and a drain electrode.

20. The OLED display of claim 15 , wherein each of the first and second selected electrodes has four corner portions, and wherein the interconnection lines are respectively connected to the four corners.

21. The OLED display of claim 15 , wherein the first interconnection lines have a substantially zigzag shape.
