Abstract
Provided is a foldable display device. The foldable display device includes a housing comprising a folding area, a first unfolding area adjacent to the folding area, and a second unfolding area adjacent to the folding area and under the first unfolding area; a display panel located at the first unfolding area and the second unfolding area that is capable of providing light through a first surface and a second surface opposite the first surface; a shutter layer on the display panel in the first unfolding area that controls whether light is transmitted; a window on the shutter layer; and a shielding layer located at the second unfolding area that is capable of blocking the light.
Claims18
A foldable display device comprising:
- a housing which comprises a folding area, a first unfolding area adjacent to the folding area, and a second unfolding area adjacent to the folding area and under the first unfolding area;
- a display panel located at the first unfolding area and the second unfolding area and capable of providing light through a first surface and a second surface opposite the first surface;
- a shutter layer on the display panel in the first unfolding area that controls whether light is transmitted;
- a window on the shutter layer;
- and
- a shielding layer located at the second unfolding area, the shielding layer being configured to block a light provided through the second surface of the display panel completely,
- wherein the shielding layer is formed continuously to cover a plurality of pixels of the display panel located at the second unfolding area, and
- wherein the shielding layer continuously extends from the second unfolding area through the folding area and does not extend into the first unfolding area.
A foldable display device comprising:
- a housing which comprises a folding area, a first unfolding area adjacent to the folding area, and a second unfolding area adjacent to the folding area and under the first unfolding area;
- a display panel located at the first unfolding area and the second unfolding area and capable of providing light through a first surface and a second surface opposite the first surface;
- a shutter layer on the display panel in the first unfolding area that controls whether light is transmitted;
- a window on the shutter layer;
- a shielding layer located at the second unfolding area that is capable of blocking the light;
- and
- a controller that controls the operation of the shutter layer and the display panel according to a mode, wherein the controller, in a folding mode in which the folding area is folded, controls at least one of the display panel located at the first unfolding area and the display panel located at the second unfolding area to provide the light and controls the shutter layer to transmit the light and, in an unfolding mode in which the folding area is not folded, controls both the display panel located at the first unfolding area and the display panel located at the second unfolding area to provide the light and controls the shutter layer not to transmit the light.
A foldable display device comprising:
- a housing comprising a first area and a second area horizontally adjacent to each other;
- a display panel located over the first area and the second area and capable of providing light through a first surface and a second surface opposite the first surface;
- a shutter layer on the second surface of the display panel in the first area that controls whether to transmit the light;
- a shielding layer on the second surface of the display panel in the second area, the shielding layer being configured to block a light provided through the second surface of the display panel completely;
- a window located at the first area and not the second area;
- and
- wherein the shielding layer is formed continuously to cover a plurality of pixels of the display panel located at the second unfolding area, and
- wherein the shielding layer extends continuously through the second area and does not extend into the first area.
