Abstract

A display device includes: a display substrate configured to be folded along a folding line; a driver detachably coupled to the display substrate; and a pad on at least one surface of the display substrate, the pad being configured to transmit a plurality of signals received from the driver to the display substrate, wherein the driver comprises an integrated circuit configured to supply the signals, a coupling portion configured to couple the driver to the display substrate, and a connector configured to couple the pad and the integrated circuit to each other.

Claims

1. A display device comprising:

a display substrate configured to be folded along a folding line;

a driver detachably coupled to the display substrate; and

a pad on at least one surface of the display substrate, the pad being configured to transmit a plurality of signals received from the driver to the display substrate,

wherein the driver comprises an integrated circuit configured to supply the signals, a coupling portion configured to couple the driver to the display substrate, and a connector configured to couple the pad and the integrated circuit to each other.

2. The display device of claim 1, wherein the pad comprises pads on respective surfaces of the display substrate.

3. The display device of claim 1, wherein the pad is at a vicinity of a folding line of the display substrate.

4. The display device of claim 1, wherein the connector is at at least one end portion of the coupling portion.

5. The display device of claim 1, wherein the connector is at a central portion of the coupling portion.

6. The display device of claim 4, wherein the display substrate is configured to be folded along the folding line so as to be coupled to the coupling portion.

7. The display device of claim 6, wherein the pad is coupled to the connector at an end portion of the coupling portion when the display substrate is coupled to the coupling portion while being in a folded state.

8. The display device of claim 5, wherein the pad is coupled to the connector at a central portion of the coupling portion when the display substrate is coupled to the coupling portion while being in an unfolded state.

9. The display device of claim 1, further comprising a motion sensor at at least one edge of the display substrate.

10. The display device of claim 9, wherein the motion sensor comprises a bending motion sensor configured to detect whether or not the display substrate is bent.

11. The display device of claim 1, wherein the display substrate comprises a dual emission structure.

12. The display device of claim 1, wherein the display substrate comprises an organic light emitting diode.

13. The display device of claim 1, wherein the driver further comprises at least one of an on/off switch, a camera, a communication device, a speaker, or an earphone hole.

14. The display device of claim 1, further comprising a stylus pen configured to be detached from the driver.

15. The display device of claim 1, wherein the folding line is at a central portion of the display substrate.

16. The display device of claim 1, further comprising a docking station configured to detach from the driver and configured to charge the driver.

17. The display device of claim 16, wherein the docking station is coupled to at least one side of the display substrate.

18. The display device of claim 16, further comprising a carrying case coupled to the docking station.

19. The display device of claim 18, wherein the display substrate is configured to be inserted into the carrying case.
