Abstract

A display device including: a flexible display panel; a first housing having an outer peripheral surface around which the flexible display panel is rolled; a jig in the first housing and connected to a first end of the flexible display panel, wherein the flexible display panel is configured to be rolled around the jig; and a second housing accommodating the first housing, wherein the jig and the first housing are configured to be rotated in different directions.

First claim

What is claimed is:

1. A display device comprising: a flexible display panel; a first housing having an outer peripheral surface around which the flexible display panel is rolled; a jig in the first housing and connected to a first end of the flexible display panel, wherein the flexible display panel is configured to be rolled inside the first housing around the jig; and a second housing accommodating the first housing, wherein the jig and the first housing are configured to be rotated in different directions, and wherein a rotating direction of a first portion of the flexible display panel in the first housing is opposite to a rotating direction of a second portion of the flexible display panel in the second housing when the flexible display panel is drawn out or retracted in.

2. The display device of claim 1 ,
wherein the first housing comprises a protruding portion having a circular, an elliptical, or a semi-circular cross-sectional shape.

3. The display device of claim 2 , further comprising:
a protective member on the protruding portion of the first housing.

4. The display device of claim 3 ,
wherein the protective member comprises one or more of the following: polycarbonate (PC), polyethyleneterephthalate (PET), polypropylene terephthalate (PPT), polyethylene naphthalate (PEN), cyclic olefin polymer (COP), cyclic olefin copolymer (COC), poly(methyl methacrylate) (PMMA), polyimide (PI), polyacrylate (PAR), polyethersulphone (PES), polyetherimide (PEI), a silicon resin, a fluorocarbon resin, and a modified epoxy resin.

5. The display device of claim 1 ,
wherein the jig is configured to be rotated using a motor or a torsion spring.

6. The display device of claim 1 ,
wherein the first housing is configured to be rotated using a motor or a torsion spring.

7. The display device of claim 1 , further comprising:
a wire connecting the flexible display panel and the jig.

8. The display device of claim 7 ,
wherein the wire comprises one or more of the following: a leaf spring, a spiral spring, and a coil spring.

9. The display device of claim 1 ,
wherein the jig is rotatably fixed to an interior of the first housing.

10. The display device of claim 1 ,
wherein the first housing is rotatably fixed to an interior of the second housing.

11. The display device of claim 1 ,
wherein the first housing has a first inlet through which the flexible display panel is drawn in or out.

12. The display device of claim 1 ,
wherein the second housing has a second inlet through which the flexible display panel is drawn in or out.

13. The display device of claim 1 , further comprising:
a handle connected to a second end of the flexible display panel.
