Abstract

A flexible display is disclosed. In one aspect, the flexible display a flexible display panel includes a display area and a peripheral area located on opposing sides of the display area and a first fixing part located over an upper surface of the peripheral area of the flexible display panel. The first fixing part is configured to have a first restoring force that presses on the upper surface of the flexible display panel. The flexible display also includes a second fixing part located below a lower surface of the peripheral area of the flexible display panel. The second fixing part is configured to have a second restoring force that presses on the lower surface of the flexible display panel.

First claim

What is claimed is:

1 . A flexible display, comprising:
a flexible display panel including a display area and a peripheral area located on opposing sides of the display area; a first fixing part located over an upper surface of the peripheral area of the flexible display panel, wherein the first fixing part is configured to have a first restoring force that presses on the upper surface of the flexible display panel; and a second fixing part located below a lower surface of the peripheral area of the flexible display panel, wherein the second fixing part is configured to have a second restoring force that presses on the lower surface of the flexible display panel.

2 . The flexible display of claim 1 , further comprising:
a first roll configured to wind the flexible display panel therearound; a second roll configured to wind the first fixing part therearound; and a third roll configured to wind the second fixing part therearound, wherein the second roll and the third roll are configured to rotate in opposite directions.

3 . The flexible display of claim 1 , wherein the first and second fixing parts are formed of a ductile material.

4 . The flexible display of claim 3 , wherein at least one of the first and second fixing parts comprises a magnet.

5 . The flexible display of claim 1 , wherein the flexible display panel further includes a plurality of holes formed in the peripheral area, wherein one of the first and second fixing parts further comprises a plurality of protrusions respectively corresponding to the holes and configured to be respectively inserted into the holes.

6 . The flexible display of claim 5 , wherein the holes are arranged in a row in the peripheral area.

7 . The flexible display of claim 5 , wherein the holes are arranged at regular intervals.

8 . The flexible display of claim 5 , wherein the first fixing part further comprises a plurality of first protrusions respectively corresponding to the holes, wherein the second fixing part further comprises a plurality of second protrusions respectively corresponding to the holes, and wherein one of the first protrusions and one of the second protrusions are configured to be inserted into each of the holes.

9 . The flexible display of claim 1 , further comprising a handle connected to an end of the flexible display panel, an end of the first fixing part, and an end of the second fixing part.

10 . A flexible display, comprising:
a flexible display panel including a display area and a peripheral area located on opposing sides of the display area; a first roll configured to wind the flexible display panel therearound; a first fixing part located over the peripheral area of the flexible display panel; and a second fixing part located under the peripheral area of the flexible display panel, wherein the first and second fixing parts are configured to have an attractive force therebetween.

11 . The flexible display of claim 10 , wherein one of the first and second fixing parts comprises a magnet and the other of the first and second fixing parts comprises a magnetic material configured to be magnetized by the magnet.

12 . The flexible display of claim 10 , wherein each of the first and second fixing parts comprises a magnet and wherein a side of the first fixing part facing the peripheral area and a side of the second fixing part facing the peripheral area have opposite polarities.

13 . The flexible display of claim 10 , wherein the first fixing part is configured to have a first restoring force which presses on an upper surface of the flexible display panel and wherein the second fixing part is configured to have a second restoring force which presses on a lower surface of the flexible display panel.

14 . The flexible display of claim 13 , further comprising:
a second roll configured to wind the first fixing part therearound; and a third roll configured to wind the second fixing part therearound, wherein the second roll and the third roll are configured to rotate in opposite directions.

15 . The flexible display of claim 13 , wherein the first and second fixing parts are formed of a ductile material.

16 . The flexible display of claim 10 , wherein the flexible display panel further includes a plurality of holes formed in the peripheral area, and wherein one of the first and second fixing parts further comprises a plurality of protrusions respectively corresponding to the holes and configured to be respectively inserted into the holes.

17 . The flexible display of claim 16 , wherein the holes are arranged in a row in the peripheral area.

18 . The flexible display of claim 16 , wherein the holes are arranged at regular intervals.

19 . The flexible display of claim 16 , wherein the first fixing part further comprises a plurality of first protrusions respectively corresponding to the holes, wherein the second fixing part further comprises a plurality of second protrusions respectively corresponding to the holes, and wherein one of the first protrusions and one of the second protrusions are configured to be inserted into each of the holes.

20 . The flexible display of claim 10 , further comprising a handle connected to an end of the flexible display panel, an end of the first fixing part, and an end of the second fixing part.
