Abstract

A display device having a flexible display panel displaying an image; and a display panel shape change part setting up a bending axis crossing the flexible display panel according to input information and bending the flexible display panel along the bending axis, as the flexible display panel is bent, the flexible display panel is divided into a first region and a second region based on the bending axis

First claim

What is claimed is:

1 . A display device comprising:
a flexible display panel for displaying an image; and a display panel shape change part for setting up a bending axis on the flexible display panel according to input information and bending the flexible display panel along the bending axis, wherein as the flexible display panel is bent, the flexible display panel is divided into a first region and a second region based on the bending axis, and the image comprises a first image being displayed on the first region and a second image which is displayed on the second region and provides independent information from the first image.

2 . The display device of claim 1 , wherein the input information comprises a projected distance obtained from projecting a distance between user groups located at a front side of the flexible display panel onto the front side of the flexible display panel and a number of respective users of the user groups.

3 . The display device of claim 2 , wherein when the projected distance exceeds a critical distance, the flexible display panel is bent.

4 . The display device of claim 3 , wherein a location of the bending axis is set within a range of the projected distance on the flexible display panel and the bending axis overlaps with the projected distance in a plane.

5 . The display device of claim 4 , wherein the flexible display panel is configured to be convexly bent around the bending axis.

6 . The display device of claim 5 , wherein the location of the bending axis is changed by the number of respective users constituting the user groups.

7 . The display device of claim 6 , wherein the location of the bending axis is set to be nearer to the user group having a smaller number of users among the user groups.

8 . The display device of claim 7 , wherein the user groups comprises:
a first user group located nearer to the first region; and a second user group located nearer to the second region, wherein the first region provides the first image to the first user group and the second region provides the second image to the second user group.

9 . The display device of claim 8 , wherein the display panel shape change part is configured to set up the bending axis so that a ratio of an area of the first region to an area of the second region is proportional to a ratio of the number of users of the first user group to the number of users of the second user group.

10 . The display device of claim 9 , wherein the flexible display panel is configured to bend so that a distance between a center of the first user group and one end of the flexible display panel adjacent to the first region is the same as a distance between the center of the first user group and the bending axis, and a distance between a center of the second user group and the other end of the flexible display panel adjacent to the second region is the same as a distance between the center of the second user group and the bending axis.

11 . The display device of claim 8 , wherein the first image and the second image provide different information from each other.

12 . The display device of claim 3 , wherein the flexible display panel is configured to concavely bent around the bending axis.

13 . The display device of claim 12 , wherein the user groups comprises:
a first user group located near to the first region; and a second user group located near to the second region, wherein the first region provides the first image to the second user group and the second region provides the second image to the first user group.

14 . The display device of claim 13 , wherein the display panel shape change part is configured to set up the bending axis so that a ratio of an area of the first region to an area of the second region is inversely proportional to a ratio of the number of users of the first user group to the number of users of the second user group.

15 . The display device of claim 14 , wherein the flexible display panel is configured to bend so that a distance between a center of the second user group and one end of the flexible display panel adjacent to the first region is the same as a distance between the center of the second user group and the bending axis, and a distance between a center of the first user group and the other end of the flexible display panel adjacent to the second region is the same as a distance between the center of the first user group and the bending axis.

16 . The display device of claim 1 , further comprising a search unit for measuring a distance obtained from projecting a distance between user groups located at a front side of the flexible display panel onto the front side of the flexible display panel and a number of respective users of the user groups,
wherein the input information is provided from the search unit.
