Abstract

A rollable display is disclosed. In one aspect, the display includes a flexible display panel having first and second opposing ends and a jig connected to the first end of the flexible display panel. The flexible display panel is configured to be rolled around the jig. The display also includes a handle connected to the second end of the flexible display panel, a housing configured to accommodate the flexible display panel when rolled around the jig and a support unit connecting the handle to the housing. The support unit includes a frame guide having a track groove defined in a surface of the frame guide and a support frame. The support frame has a first end rotatably connected to one of the handle or the housing and a second end slidably connected to the track groove of the frame guide.

First claim

What is claimed is:

1. A rollable display, comprising:
a flexible display panel having first and second opposing ends;
a jig connected to the first end of the flexible display panel and having an outer circumferential surface, wherein the flexible display panel is configured to be rolled around the outer circumferential surface of the jig;
a handle connected to the second end of the flexible display panel;
a housing configured to accommodate the flexible display panel when rolled around the jig; and
a support unit connecting the handle to the housing,
wherein the support unit includes:
a frame guide having a track groove defined in a surface of the frame guide; and
a support frame having i) a first end rotatably connected to one of the handle or the housing and ii) a second end slidably connected to the track groove of the frame guide.

2. The display of claim 1 , wherein the support frame includes:
a frame body having a fastening hole defined in a first end thereof;
an engaging portion configured to be inserted into the track groove of the frame guide; and
a connecting portion connecting the engaging portion to a second end of the frame body.

3. The display of claim 2 , wherein the track groove has a cross-sectional shape selected from the following: a circular shape, an elliptical shape, a dovetail shape, a truncated triangular shape, a rhombus shape, and a trapezoidal shape.

4. The display of claim 3 , wherein the engaging portion has a cross-sectional shape that is substantially the same as that of the track groove.

5. The display of claim 2 , wherein the frame guide further includes a fixing groove formed at one end of the track groove and extending in a direction so as to form an angle with the track groove.

6. The display of claim 1 , wherein the frame guide includes a first track groove defined in a first surface of the frame guide and a second track groove defined in a second surface of the frame guide opposing the first surface.

7. The display of claim 6 , wherein the support frame includes:
a first support frame connecting the handle to the first track groove; and
a second support frame connecting the housing to the second track groove,
wherein the first and second support frames are respectively connected to the handle and the housing on opposing sides of the flexible display panel.

8. The display of claim 6 , wherein the support frame includes:
a first support frame connecting the handle to the first track groove;
a second support frame connecting the housing to the first track groove;
a third support frame connecting the handle to the second track groove;
a fourth support frame connecting the housing to the second track groove,
wherein the first and second support frames are rotatably connected to a common connecting portion, and
wherein the third and fourth support frames are rotatably connected to a common connecting portion.

9. The display of claim 1 , wherein the frame guide includes first and second track grooves defined in a first surface of the frame guide, wherein the first and second track grooves are substantially parallel to each other, wherein the frame guide further includes third and fourth track grooves defined in a second surface of the frame guide opposing the first surface, wherein the third and fourth track grooves are substantially parallel to each other.

10. The display of claim 9 , wherein the support frame includes:
a first support frame connecting the handle to the first track groove;
a second support frame connecting the housing to the second track groove;
a third support frame connecting the handle to the third track groove; and
a fourth support frame connecting the housing to the fourth track groove,
wherein the first and second support frames are respectively connected to the handle and the housing on opposing sides of the flexible display, and
wherein the third and fourth support frames are respectively connected to the handle and the housing on opposing sides of the flexible display.

11. The display of claim 10 , wherein the first and second support frames are arranged so as to have substantially the same height and wherein the third and fourth support frames are arranged so as to have substantially the same height.

12. The display of claim 6 , wherein the first and second support frames are respectively connected to the handle and the housing on the same side of the flexible display and wherein the third and fourth support frames are respectively connected to the handle and the housing on the same side of the flexible display.

13. A rollable display, comprising:
a flexible display panel having first and second ends opposing each other;
a jig connected to the first end of the flexible display panel and having an outer circumferential surface, wherein the flexible display panel is configured to be rolled around the outer circumferential surface of the jig;
a handle connected to the second end of the flexible display panel, wherein the handle includes a track groove defined in a surface of the handle;
a housing configured to accommodate the flexible display panel when rolled around the jig; and
a support frame having a first end rotatably connected to the housing and a second end slidably connected to the track groove of the handle.

14. The display of claim 13 , wherein the support frame includes:
a frame body having a fastening hole formed at a first end thereof;
an engaging portion inserted into the track groove; and
a connecting portion connecting the engaging portion to a second end of the frame body.

15. The display of claim 14 , wherein the track groove has a cross-sectional shape selected from the following: a circular shape, an elliptical shape, a dovetail shape, a truncated triangular shape, a rhombus shape, and a trapezoidal shape.

16. The display of claim 14 , wherein the engaging portion has a cross-sectional shape that is substantially the same as that of the track groove.

17. The display of claim 14 , wherein the frame guide further includes a fixing groove formed at one end of the track groove and extending in a direction so as to form an angle with the track groove.

18. The display of claim 14 , wherein the handle has first and second track grooves defined in a surface of the handle, wherein the first and second track grooves are substantially parallel to one another.

19. The display of claim 18 , wherein the support frame includes:
a first support frame connecting the housing to the first track groove; and
a second support frame connecting the housing to the second track groove to one another,
wherein the first and second support frames are arranged so as to have different heights from one another.

20. The display of claim 1 , wherein the housing includes an inlet through which the flexible display panel is configured to be drawn in or out.
