Abstract
A display device includes a display panel including a first area, a folding area, and a second area, the folding area being foldable about a folding axis, a first plate disposed on a rear surface of the display panel in the first area, a second plate disposed on the rear surface of the display panel in the second area and spaced apart from the first plate, a flexible thin-film layer disposed on the rear surface and including a first portion covering at least an area of the first plate, a second portion covering at least an area of the second plate, and a third portion connecting the first and second portions and disposed on the folding area, and a guide that covers the second portion of the flexible thin-film layer and at least an area of the second plate.
Claims20
A display device comprising:
- a display panel including a first area, a folding area, and a second area arranged in a first direction, the folding area being foldable about a folding axis parallel to a second direction intersecting the first direction;
- a first plate disposed on a rear surface of the display panel in the first area;
- a second plate disposed on the rear surface of the display panel in the second area and spaced apart from the first plate in the first direction;
- a flexible thin-film layer disposed on the rear surface of the display panel and including:
- a first portion covering at least an area of the first plate;
- a second portion covering at least an area of the second plate;
- and
- a third portion connecting the first portion and the second portion and disposed on the folding area;
- and
- a guide that covers the second portion of the flexible thin-film layer and at least an area of the second plate, wherein
- in case that the display panel is converted between a folded state and an unfolded state,
- the first portion of the flexible thin-film layer is attached to the first plate, and
- the second portion of the flexible thin-film layer slides between the guide and the second plate.
A foldable electronic device comprising:
- a first housing;
- a second housing connected to the first housing through a hinge structure and rotatable about the hinge structure;
- a display panel disposed on an area of the first housing and an area of the second housing and foldable by rotation;
- a first plate disposed on a rear surface of the display panel and facing the first housing;
- a second plate disposed on the rear surface of the display panel, facing the second housing, and spaced apart from the first plate in a first direction;
- a flexible thin-film layer comprising:
- a first portion disposed on the rear surface of the display panel and overlapping the first plate in a thickness direction of the display panel;
- a second portion overlapping the second plate in the thickness direction;
- and
- a third portion connecting the first portion and the second portion and disposed on the hinge structure;
- and
- a guide disposed on at least an area of the second plate and a rear surface of the second portion of the flexible thin-film layer, wherein
- in case that the display panel is converted between a folded state and an unfolded state,
- the first portion of the flexible thin-film layer is attached to the first plate, and
- the second portion of the flexible thin-film layer slides under guidance of the guide.
