Abstract

A display device is disclosed. The display device includes a flexible display panel, a flexible plate positioned at a rear of the flexible display panel, a rigid bar adjacent to an edge of a back surface of the flexible plate, a drive unit installed to a rear of the flexible plate, and a wing plate connecting the drive unit to the rigid bar and hinge-coupled to the rigid bar.

First claim

What is claimed is:

1. A display device comprising:
a flexible display panel;
a flexible plate disposed at a rear side of the flexible display panel;
a rigid bar disposed at a rear side of the flexible plate and adjacent to an edge of the flexible plate;
a drive unit disposed at the rear side of the flexible plate; and
a wing plate coupling the drive unit to the rigid bar, wherein the wing plate is hingedly coupled to the rigid bar;
a side frame disposed adjacent to an edge of the flexible plate wherein a portion of the side frame is separated from the flexible plate;
a side adhesive member disposed at a front side of the side frame; and
a magnetic coupling member disposed at a part of a front side of the flexible plate,
wherein a part of a rear surface of the flexible display panel is attached to the side adhesive member, and
wherein another part of the rear surface of the flexible display panel is in contact with the magnetic coupling member.

2. The display device of claim 1 , further comprising a side frame disposed between the flexible display panel and the rigid bar.

3. The display device of claim 2 , wherein the drive unit is configured to apply a force to the side frame in a first direction or a second direction.

4. The display device of claim 3 , wherein an edge of the side frame is separated from an edge of the flexible plate by a gap.

5. The display device of claim 4 , wherein a width of the gap increases when the drive unit applies the force in the first direction and decreases when the drive unit applies the force in the second direction.

6. The display device of claim 1 , wherein the drive unit is configured to apply a force to the rigid bar in a first direction or a second direction via the wing plate.

7. The display device of claim 6 , wherein the edge of the flexible plate is moved such that a rear side of the flexible plate is concave when the drive unit applies the force in the second direction.

8. The display device of claim 6 , wherein the edge of the flexible plate is moved such that a front side of the flexible plate is concave when the drive unit applies the force in the first direction.

9. The display device of claim 1 , further comprising a side frame disposed between the flexible display panel and the rigid bar,
wherein the flexible plate comprises a boss disposed at the rear side of the flexible plate and adjacent to the rigid bar, and
wherein the side frame comprises a groove corresponding to the boss.

10. The display device of claim 9 , wherein:
the drive unit is configured to apply a force to the rigid bar via the wing plate in a first direction or a second direction;
the boss is moved toward the groove when the drive unit applies the force in the first direction; and
the boss is moved away from the groove when the drive unit applies the force in the second direction.

11. The display device of claim 1 , further comprising a side frame disposed between the flexible display panel and the rigid bar,
wherein the side frame comprises a guide groove extending parallel to a longitudinal direction of the wing plate; and
wherein the flexible plate comprises a guide pin disposed at the rear side of the flexible plate and configured to be inserted into the guide groove.

12. The display device of claim 11 , wherein:
the drive unit is configured to apply a force to the rigid bar in a first direction or a second direction via the wing plate; and
the guide pin is configured to travel along the guide groove when the force is applied by the drive unit.

13. The display device of claim 1 , further comprising a center rigid bar disposed between the flexible plate and the drive unit.

14. The display device of claim 1 , wherein the drive unit further comprises:
a housing;
a guide rail;
a slider configured to travel along the guide rail; and
a lead shaft mounted on the housing and screw-coupled to the slider,
wherein the wing plate is hingedly coupled to the slider.

15. The display device of claim 14 , further comprising a center rigid bar disposed at the rear side of the flexible plate,
wherein the drive unit is mounted on the center rigid bar.

16. The display device of claim 1 , further comprising:
a center adhesive member disposed at a center portion of the front side of the flexible plate and coupled to the center portion,
wherein the center adhesive member and the side adhesive member are coupled to a rear side of the flexible display panel.

17. The display device of claim 16 , wherein the magnetic coupling member is disposed between the center adhesive member and the side adhesive member at the front side of the flexible plate.

18. The display device of claim 16 , wherein the center adhesive member extends vertically at the center portion and the side adhesive member extends vertically at the front side of the side frame.

19. The display device of claim 1 , further comprising a boss disposed at the rear side of the flexible plate,
wherein the rigid bar is coupled to the boss by a fastening member.
