Abstract

Display of a display device is made less likely to appear divided when a plurality of display panels are used as one screen. Provided is a display device including two display units and a foldable housing that includes a joint portion between the two display units and supports the two display units. Each display unit includes a display panel including a display region and a non-display region and a support having a first surface overlapped with the display region and a second surface that meets the first surface and is overlapped with the non-display region. The two display units are placed in the housing in an opened state such that the first surfaces of the supports face the same direction and the second surfaces of the supports face each other.

First claim

The invention claimed is:

1. A display device comprising:
a first display unit;
a second display unit;
a first display panel overlapping the first display unit;
a second display panel overlapping the second display unit; and
a housing connecting the first display unit and the second display unit with a joint portion therebetween, whereby the display device is configured to be opened or folded,
wherein a side surface of the first display unit and a side surface of the second display unit face each other when the display device is opened, and
wherein the first display panel is bent along the side surface of the first display unit such that a display region of the first display panel is exposed when the display device is folded.

2. The display device according to claim 1 , wherein the first display panel comprises a capacitive touch sensor.

3. The display device according to claim 1 , wherein the first display panel comprises an optical touch sensor.

4. The display device according to claim 1 , wherein the first display panel comprises a light-emitting element.

5. The display device according to claim 1 , wherein the first display panel is flexible.

6. The display device according to claim 1 , the first display panel and the second display panel are configured to perform display when the display device is opened.

7. The display device according to claim 1 , wherein the housing comprises a projection to fix the first display unit.

8. A display device comprising:
a first display unit;
a second display unit;
a first display panel overlapping the first display unit;
a second display panel overlapping the second display unit; and
a housing connecting the first display unit and the second display unit with a joint portion therebetween, whereby the display device is configured to be opened or folded,
wherein a side surface of the first display unit and a side surface of the second display unit face each other when the display device is opened,
wherein the first display panel is bent along the side surface of the first display unit such that a display region of the first display panel is exposed when the display device is folded, and
wherein the second display panel is bent along the side surface of the second display unit such that a display region of the second display panel is exposed when the display device is folded.

9. The display device according to claim 8 , wherein the first display panel comprises a capacitive touch sensor.

10. The display device according to claim 8 , wherein the first display panel comprises an optical touch sensor.

11. The display device according to claim 8 , wherein the first display panel comprises a light-emitting element.

12. The display device according to claim 8 , wherein the first display panel is flexible.

13. The display device according to claim 8 , wherein the first display panel and the second display panel are configured to perform display when the display device is opened.

14. The display device according to claim 8 , wherein the housing comprises a projection to fix the first display unit.

15. A display device comprising:
a first display unit;
a second display unit;
a first display panel overlapping the first display unit; and
a housing connecting the first display unit and the second display unit with a joint portion therebetween, whereby the display device is configured to be opened or folded,
wherein the first display panel comprises a display region and a non-display region in the joint portion when the display device is folded.

16. The display device according to claim 15 , wherein the first display panel comprises a capacitive touch sensor.

17. The display device according to claim 15 , wherein the first display panel comprises an optical touch sensor.

18. The display device according to claim 15 , wherein the first display panel comprises a light-emitting element.

19. The display device according to claim 15 , wherein the first display panel is flexible.

20. The display device according to claim 15 , wherein the first display panel is configured to perform display when the display device is opened.

21. The display device according to claim 15 , wherein the first display unit is fixed to the housing with a projection of the housing.
