Abstract

A rollable display is disclosed. In one aspect, the rollable display includes a flexible display panel, a housing having an internal space defined therein, and a rolling member positioned in the housing and configured to have the flexible display panel rolled therearound. The rollable display also includes a guide member positioned in the housing and having a coil shape. The guide member is configured to separate portions of the flexible display panel from each other.

First claim

What is claimed is:

1. A rollable display, comprising:
a flexible display panel;
a housing having an internal space defined therein;
a rolling member positioned in the housing and configured to have the flexible display panel rolled therearound; and
a guide member positioned in the housing and having a coil shape, wherein the guide member is configured to separate portions of the flexible display panel from each other and has a spiral structure integrated into the housing.

2. The rollable display of claim 1 , wherein the flexible display panel includes a display area configured to display an image and wherein the display area is configured to be supported by the guide member when the flexible display panel is rolled around the rolling member.

3. The rollable display of claim 2 , wherein the length of the guide member is substantially the same as the length of the display area of the flexible display panel.

4. The rollable display of claim 1 , further comprising a handle attached to one end of the flexible display panel and having a bar shape.

5. The rollable display of claim 1 , wherein the housing has an opening formed therein, wherein the flexible display panel is configured to be withdrawn from the opening, wherein the rollable display further comprises a foreign material introduction preventing member formed along an edge of the opening, and wherein foreign material introduction preventing member is configured to be in close contact with upper and lower surfaces of the flexible display panel.

6. The rollable display of claim 5 , wherein the foreign material introduction preventing member is formed of at least one of the following: brush, cloth, and rubber.

7. The rollable display of claim 5 , wherein one end of the guide member is positioned adjacent to the rolling member, and wherein the other end of the guide member is positioned adjacent to the opening.

8. The rollable display of claim 1 , wherein the guide member has a surface configured to prevent static electricity, and wherein the flexible display panel is configured to contact the surface of the guide member.

9. The rollable display of claim 1 , wherein the rolling member comprises a circuit board configured to driver the flexible display panel and wherein the rolling member is connected to the flexible display panel via the circuit board.

10. The rollable display of claim 1 , wherein the flexible display panel includes: i) a display area configured to display an image and ii) a non-display area, wherein the flexible display panel is connected to the rolling member via the non-display area, wherein the guide member is spaced apart from the rolling member, and wherein the non-display area is configured to be rolled around the rolling member a plurality of times between the rolling member and the guide member.

11. The rollable display of claim 1 , wherein the spiral structure has different portions having different lengths and formed between the portions of the display panel.

12. The rollable display of claim 1 , wherein the guide member separates the portions of the flexible display panel in a radial direction of the housing.

13. A rollable display, comprising:
a flexible display panel;
a housing having an internal space defined therein;
a rolling member positioned in the housing and configured to have the flexible display panel rolled therearound; and
a guide member positioned in the housing and having a spiral structure, wherein the spiral structure separates different portions of the flexible display panel from each other in a radial direction of the housing.

14. The rollable display of claim 13 , wherein the flexible display panel includes a display area configured to display an image and wherein the display area is configured to be supported by the guide member when the flexible display panel is rolled around the rolling member.

15. The rollable display of claim 13 , further comprising a handle attached to one end of the flexible display panel and having a bar shape.

16. The rollable display of claim 13 , wherein the housing has an opening formed therein, wherein the flexible display panel is configured to be withdrawn from the opening, wherein the rollable display further comprises a foreign material introduction preventing member formed along an edge of the opening, and wherein foreign material introduction preventing member is configured to be in close contact with upper and lower surfaces of the flexible display panel.

17. The rollable display of claim 16 , wherein one end of the guide member is positioned adjacent to the rolling member, and wherein the other end of the guide member is positioned adjacent to the opening.

18. The rollable display of claim 13 , wherein the rolling member comprises a circuit board configured to driver the flexible display panel and wherein the rolling member is connected to the flexible display panel via the circuit board.

19. The rollable display of claim 13 , wherein the flexible display panel includes: i) a display area configured to display an image and ii) a non-display area, wherein the flexible display panel is connected to the rolling member via the non-display area, wherein the guide member is spaced apart from the rolling member, and wherein the non-display area is configured to be rolled around the rolling member a plurality of times between the rolling member and the guide member.
