Flexible display apparatus
A flexible display apparatus includes: a flexible substrate including a bending area and a non-bending area; and a wiring line extending across the bending area. The bending area is configured to bend along a bending axis, and a portion of the wiring line at the bending area includes a plurality of recessed portions recessed in a width direction of the wiring line.
1. A flexible display apparatus comprising:
a flexible substrate comprising a bending area and a non-bending area, the bending area being configured to bend along a bending axis; and
a wiring line extending across the bending area, a portion of the wiring line at the bending area comprising a plurality of first recessed portions and a plurality of second recessed portions, the first and second recessed portions being recessed in a width direction of the wiring line,
wherein the wiring line has a central axis that extends in a second direction, and the plurality of recessed portions are on both sides of the wiring line about the central axis,
wherein the plurality of recessed portions comprise a plurality of first recessed portions that are on one side of the wiring line about the central axis and a plurality of second recessed portions that are on another side of the wiring line about the central axis,
wherein the first recessed portions and the second recessed portions are alternately arranged along the second direction,
wherein the wiring line has a first width, the first width being a greatest width of the wiring line, and a recessed depth of each of the plurality of recessed portions is less than half the first width, and
wherein the recessed portions do not cross the central axis of the wiring line.
2. The flexible display apparatus of claim 1 , wherein a width of each of the plurality of recessed portions is less than the recessed depth of each of the plurality of recessed portions.
3. The flexible display apparatus of claim 1 , wherein a minimum distance between adjacent ones of the recessed portions on one side of the wiring line from among the plurality of recessed portions is greater than the first width.
4. The flexible display apparatus of claim 3 , wherein the minimum distance between adjacent ones of the recessed portions on one side of the wiring line from among the plurality of recessed portions is greater than two times the first width.
5. The flexible display apparatus of claim 1 , wherein the plurality of recessed portions have polygonal shapes, elliptical shapes, circular shapes, partial polygonal shapes, partial elliptical shapes, or partial circular shapes.
6. The flexible display apparatus of claim 1 , further comprising a sensor configured to sense an external touch, wherein the wiring line is on a same layer as the sensor.
7. The flexible display apparatus of claim 6 , wherein the wiring line is electrically connected to the sensor.
8. The flexible display apparatus of claim 6 , wherein the wiring line is adjacent to the sensor.
9. The flexible display apparatus of claim 1 , wherein the recessed portions on one side of the wiring line are alternately arranged with the recessed portions on another side of the wiring line along the second direction.
10. A flexible display apparatus comprising:
a flexible substrate comprising a bending area and a non-bending area, the bending area being configured to bend along a bending axis; and
a wiring line extending across the bending area, a portion of the wiring line at the bending area comprising a plurality of recessed portions recessed in a width direction of the wiring line,
wherein the wiring line has a central axis that extends in a second direction, the plurality of recessed portions are on both sides of the wiring line about the central axis, and a minimum distance between adjacent ones of the recessed portions on one side of the wiring line from among the plurality of recessed portions is greater than a recessed depth of each of the plurality of recessed portions,
wherein the wiring line has a first width, the first width being a greatest width of the wiring line, and a recessed depth of each of the plurality of recessed portions is less than half the first width, and
wherein the recessed portions do not cross the central axis of the wiring line.
11. The flexible display apparatus of claim 10 , wherein the minimum distance between adjacent ones of the recessed portions on one side of the wiring line from among the plurality of recessed portions is greater than four times the recessed depth of each of the plurality of recessed portions.
12. The flexible display apparatus of claim 10 , wherein the minimum distance between adjacent ones of the recessed portions on one side of the wiring line from among the plurality of recessed portions is greater than two times the first width.
13. The flexible display apparatus of claim 10 , wherein the plurality of recessed portions have polygonal shapes, elliptical shapes, circular shapes, partial polygonal shapes, partial elliptical shapes, or partial circular shapes.
14. The flexible display apparatus of claim 10 , further comprising a sensor configured to sense an external touch, wherein the wiring line is on a same layer as the sensor.
15. The flexible display apparatus of claim 14 , wherein the wiring line is electrically connected to the sensor.
16. The flexible display apparatus of claim 14 , wherein the wiring line is adjacent to the sensor.
17. The flexible display apparatus of claim 10 , wherein the recessed portions on one side of the wiring line are alternately arranged with the recessed portions on another side of the wiring line along the second direction.
