Flexible display device with side crack protection structure and manufacturing method for the same
There is provided a flexible display having a plurality of innovations configured to allow bending of a portion or portions to reduce apparent border size and/or utilize the side surface of an assembled flexible display.
1. A display device comprising:
a flexible base layer having a bend portion, an upper area, a left curve portion, a right curve portion and a flat area surrounded by the bend portion, the upper area, the left curve portion and the right curve portion, bending angles of the left and right curve portions being smaller than a bending angle of the bend portion; and
the bend portion having notches located where the right and left curve portions meet the bend portion respectively,
wherein a width of the bend portion is smaller than a total width of the flat area, the left curve portion and the right curve portion, and
wherein the left and right curve portions further comprise:
a crack stopper structure,
a gate-in-panel (GIP) between the flat area and the crack stopper structure, and
an electro static discharge (ESD) circuit.
2. The display device of claim 1 , wherein the bending angles of the left and right curve portions are less than 90 degrees.
3. The display device of claim 1 , wherein the bending angle of the bend portion is more than 90 degrees.
4. The display device of claim 1 , wherein the notches have a round shape.
5. The display device of claim 1 , wherein the ESD circuit on the left and right curve portions is located near the bend portion.
6. The display device of claim 1 , wherein the ESD circuit on the left and right curve portions, is located near the upper area.
7. The display device of claim 1 , wherein the ESD circuit is located where the left or right curve portions meets the upper area.
8. The display device of claim 1 , wherein the ESD circuit is located between the GIP and the notches.
9. A display device comprising:
a flexible base layer having a bend portion, an upper area, a left curve portion, a right curve portion and a flat area surrounded by the bend portion, the upper area, the left curve portion and the right curve portion, bending angles of the left and right curve portions being smaller than a bending angle of the bend portion;
a crack stopper structure and an electro static discharge (ESD) on the left or right curve portion; and
a gate-in-panel (GIP) between the flat area and the crack stopper structure, located on the left or right curve portion.
10. The display device of claim 9 , wherein the bending angles of the left and right curve portions are less than 90 degrees.
11. The display device of claim 9 , wherein the bending angle of the bend portion is more than 90 degrees.
12. The display device of claim 9 , wherein the crack stopper structure has a recessed channel shape.
13. The display device of claim 9 , wherein the ESD circuit on the left and right curve portions, is located near the bend portion.
14. The display device of claim 9 , wherein the ESD circuit, on the left and right curve portions, is located near the upper area.
15. The display device of claim 9 , wherein the ESD circuit is located where the left or right curve portion meets the upper area.
16. A display device comprising:
a flexible base layer having a bend portion, an upper area, a left curve portion, a right curve portion and a flat area surrounded by the bend portion, the upper area, the left curve portion and the right curve portion, and bending angles of the left and right curve portion being smaller than a bending angle of the bend portion;
the bend portion having notches located where the right and left curve portions meet the bend portion respectively;
a crack stopper structure and an electro static discharge (ESD) circuit on the left or right curve portion; and
a gate-in-panel (GIP) between the flat area and the crack stopper structure, located on the left or right curve portion;
wherein a width of the bend portion is smaller than a total width of the flat area, the left curve portion and the right curve portion.
17. The display device of claim 16 , wherein the bending angles of the left and right curve portion are less than 90, and the bending angle of the bend portion is more than 90.
18. The display device of claim 16 , wherein the ESD circuit is located near the bend portion, the upper area or where the left or right curve portion meets the upper area.
