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) over the stretchable substrate and comprising 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 a corner portion of one selected from among the plurality of electrodes of the OLED and the plurality of electrodes of the TFT,
wherein the selected electrode has at least four corners, and the interconnection lines are respectively connected to the four corners, and
wherein the interconnection lines and the selected electrode are movable in a stretching direction.

2. The OLED display of claim 1 , wherein a selected electrode is rotatable.

3. The OLED display of claim 1 , wherein the selected electrode has a square shape.

4. The OLED display of claim 3 , wherein the interconnection lines connected to opposite corners of the selected electrode are stretchable opposite to each other.

5. The OLED display of claim 4 , wherein the interconnection lines connected to the four corners are arranged at a regular interval of 90 degrees.

6. The OLED display of claim 3 , wherein the interconnection lines are respectively connected to four corners of the selected electrode of the square shape and extended to outside the selected electrode from the four corners, and directions in which the interconnection lines extend are not in parallel with a center line between two facing sides of the selected electrode of the square shape.

7. The OLED display of claim 6 , wherein the interconnection lines connected to the four corners each extends from one of two facing sides of the electrode of the square shape toward the other of the two facing sides while forming an entirely whirlwind shape.

8. The OLED display of claim 7 , wherein the whirlwind shape is made in a clockwise direction or in a counter-clockwise direction.

9. The OLED display of claim 1 , wherein the interconnection lines comprise a bent portion configured to be straightened when the stretchable substrate is stretched.

10. The OLED display of claim 1 , 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.

11. The OLED display of claim 10 , wherein the selected electrode includes the pixel electrode.

12. The OLED display of claim 10 , wherein the selected electrode includes the gate electrode.

13. The OLED display of claim 10 , wherein the selected electrode includes the source electrode.

14. The OLED display of claim 10 , wherein the selected electrode includes the drain electrode.

15. The OLED display of claim 10 , wherein the selected electrode includes the opposite electrode.
