Abstract

A display device includes a first housing, a second housing separable from the first housing, a display panel in the first housing and connected to the second housing, the display panel being pulled out from the first housing when the second housing moves away from the first housing, and a support member in the second housing and connected to the first housing, the support member supporting the display panel and being pulled out from the second housing when the first housing moves away from the second housing.

First claim

What is claimed is:

1 . A display device, comprising:
a first housing; a second housing separable from the first housing; a display panel in the first housing and connected to the second housing, the display panel being pulled out from the first housing when the second housing moves away from the first housing; and a support member in the second housing and connected to the first housing, the support member supporting the display panel and being pulled out from the second housing when the first housing moves away from the second housing.

2 . The display device as claimed in claim 1 , further comprising a control board connected to the display panel, the control board being in the first housing or the second housing.

3 . The display device as claimed in claim 2 , further comprising a battery in the first housing or the second housing, the battery being electrically connected to the control board.

4 . The display device as claimed in claim 1 , further comprising a roller in at least one of the first housing and the second housing, at least one of the display panel and the support member being wound around the roller.

5 . The display device as claimed in claim 4 , wherein the roller includes:
a first roller in the first housing, one of the display panel and the support member being wound on the first roller; and a second roller in the second housing, the other one of the display panel and the support member being wound around the second roller.

6 . The display device as claimed in claim 4 , further comprising an elastic unit that applies a restoring force to the roller.

7 . The display device as claimed in claim 4 , further comprising a driver that rotates the roller to wind or unwind the at least one of the display panel and the support member.

8 . The display device as claimed in claim 1 , wherein at least one of the display panel and the support member slides along at least one of an inner surface of the first housing and an inner surface of the second housing.

9 . The display device as claimed in claim 8 , further comprising a sliding portion connected to at least one of the display panel and the support member, the sliding portion moving along the inner surface of the first or second housing.

10 . The display device as claimed in claim 9 , further comprising a stopper in the first housing or the second housing, the stopper limiting a path of the sliding portion.

11 . The display device as claimed in claim 9 , further comprising a guide portion on at least one of the inner surface of the first housing and the inner surface of the second housing, the guide portion guiding movement of the sliding portion.

12 . The display device as claimed in claim 1 , wherein the support member is a metal foil.

13 . The display device as claimed in claim 1 , further comprising an insulating member between the support member and the display panel.

14 . The display device as claimed in claim 1 , wherein the display panel is an organic light-emitting display panel.

15 . The display device as claimed in claim 1 , wherein the display panel is flexible.

16 . The display device as claimed in claim 1 , wherein the display panel includes:
a substrate; a display unit on the substrate; and a thin-film encapsulation layer on the display unit, the thin-film encapsulation layer encapsulating the display unit.

17 . The display device as claimed in claim 16 , wherein the substrate includes polyimide (PI).

18 . The display device as claimed in claim 16 , wherein the thin-film encapsulation layer includes at least one of an organic layer and an inorganic layer.

19 . The display device as claimed in claim 1 , wherein the second housing includes a support protrusion on which at least a portion of the support member is seated and supported.

20 . The display device as claimed in claim 1 , wherein the display panel is pulled out from the first housing in a first direction, and the support member is pulled out from the second housing in a second direction that is opposite to the first direction.
