Flexible display devices
A flexible display device is disclosed. In one aspect, the flexible display device includes a display panel having a flat region, a boundary region, and a bending region. The flexible display device also includes a protective structure having a first portion formed under the flat region and a second portion formed under the boundary region. A thickness of the first portion is substantially uniform. A thickness of the second portion decreases along a direction from the flat region toward the bending region.
1. A flexible display device, comprising:
a substrate having a flat region, a bending region, and a boundary region disposed between the flat region and the bending region;
an organic light-emitting structure disposed on the substrate;
an encapsulation layer disposed on the organic light-emitting structure; and
a protective structure disposed opposite to the organic light emitting structure with the substrate disposed therebetween, the protective structure having a first portion disposed under the flat region and a second portion disposed under the boundary region,
wherein a thickness of the first portion is substantially uniform, and
wherein a thickness of the second portion decreases in a discontinuous manner along a direction from the flat region toward the bending region.
2. The flexible display device of claim 1 , wherein the thickness of the second portion decreases in a stepped manner along a direction from the flat region toward the bending region.
3. A flexible display device, comprising:
a display panel having a first flat region, a second flat region, a bending region disposed between the first flat region and a second flat region, a first boundary region disposed between the first flat region and the bending region, and a second boundary region disposed between the second flat region and the bending region;
a first protective structure having a first portion disposed under the first flat region and a second portion disposed under the first boundary region,
wherein a thickness of the first portion is substantially uniform,
wherein a thickness of the second portion decreases in a discontinuous manner along a direction from the first flat region toward the bending region; and
a second protective structure having a third portion under the second flat region and a fourth portion under the second boundary region,
wherein a thickness of the third portion is substantially uniform,
wherein a thickness of the fourth portion decreases in a discontinuous manner along a direction from the second flat region toward the bending region, and
wherein the first protective structure and the second protective structure are spaced apart from each other with a gap therebetween.
4. The flexible display device of claim 3 , wherein the thickness of at least one of the second portion and the fourth portion decreases in a stepped manner along a direction from the flat region toward the bending region.
5. The flexible display device of claim 1 , wherein the protective structure overlaps only the flat region and the boundary region.
6. The flexible display device of claim 1 , wherein the organic light-emitting structure is configured to display image and overlaps the flat region, the bending region, and the boundary region.
7. The flexible display device of claim 1 , wherein the flat region is unbendable or rigid.
