Abstract

A display apparatus includes a first roller and a second roller each rolling about a rolling axis extending along a first direction and spaced apart from each other in a second direction crossing the first direction, a display panel connected to the first roller, and a support connected to the second roller and disposed on a rear surface of the display panel to support the display panel. A hole passing through the support is defined in the support, the support includes an end part surrounding a portion of the hole and extending along the first direction and a side part extending along the second direction from the end part, and the end part is convex toward the display panel in a cross section.

First claim

What is claimed is:

1 . A display apparatus comprising:
a first roller and a second roller each rolling about a rolling axis extending along a first direction and spaced apart from each other in a second direction crossing the first direction; a display panel connected to the first roller; and a support which is connected to the second roller and disposed on a rear surface of the display panel and supports the display panel and through which at least one hole passing through the support is defined, the support comprising:
an end part surrounding a portion of the at least one hole, extending along the first direction and convex toward the display panel in a cross section; and
a side part extending along the second direction from the end part,
wherein the at least one hole is provided in single in the second direction, and a length of the hole in the second direction is about 30% or less of a length of the support in the second direction, or wherein the at least one hole is provided in plural in the second direction so that a plurality of holes is spaced apart from each other along the second direction, and a sum of lengths of the plurality of holes in the second direction is about 30% or less of the length of the support in the second direction.

2 . The display apparatus of claim 1 , wherein the length of the hole in the second direction is greater than a width of the hole in the first direction.

3 . The display apparatus of claim 1 , wherein the sum of lengths of the plurality of holes in the second direction is greater than a width of each of the plurality of holes in the first direction.

4 . The display apparatus of claim 1 , wherein the plurality of holes is spaced apart from each other along the first direction.

5 . The display apparatus of claim 4 , wherein a length of each of the plurality of holes in the second direction is greater than a sum of widths of the plurality of holes in the first direction.

6 . The display apparatus of claim 1 , wherein the hole has a circular, oval, or quadrangular shape in a plan view.

7 . The display apparatus of claim 1 , wherein in a state in which the display panel is wound on the first roller, the end part supports the display panel, and at least a portion of the side part is wound on the second roller.

8 . The display apparatus of claim 1 , wherein in a state in which the display panel is unwound from the first roller, the support supports an unwound portion of the display panel.

9 . The display apparatus of claim 1 , wherein the support is a bistable reeled composite.

10 . The display apparatus of claim 1 , wherein the support is provided in plural, and
a plurality of supports is spaced apart from each other along the first direction.

11 . The display apparatus of claim 1 , wherein a rotation direction of the first roller which unwinds the display panel and a rotation direction of the second roller which unwinds the support are opposed to each other.

12 . A display apparatus comprising:
a display panel rolled about a first rolling axis extending along a first direction; a guide roller extending in the first direction; and a support rolled about a second rolling axis extending along the first direction and spaced apart from the first rolling axis, wherein a hole passing through the support is defined in the support, the hole is adjacent to an end of the support extending along the first direction, and the support is a bistable reeled composite, wherein, the at least one hole is provided in single in the second direction, and a length of the hole in the second direction is about 30% or less of a length of the support in the second direction, or wherein, the at least one hole is provided in plural in the second direction so that a plurality of holes is spaced apart from each other along the second direction, and a sum of lengths of the plurality of holes in the second direction is about 30% or less of the length of the support in the second direction.

13 . The display apparatus of claim 12 , wherein a first portion of the support wound about the second rolling axis is flat along the first direction, and
a second portion of the support which is unwound about the second rolling axis and extends along a second direction crossing the first direction is convex toward the display panel.

14 . The display apparatus of claim 13 , wherein the length of the hole in the second direction is greater than a width of the hole in the first direction.

15 . The display apparatus of claim 12 , wherein a rotation direction of the display panel rolled about the first rolling axis and a rotation direction of the support rolled about the second rolling axis are opposed to each other.
