Flexible touch display cover window layer design
In one embodiment, a touch display device includes a substrate, a display layer, a touch layer and a cover window layer. The substrate includes a foldable region. The display layer is disposed on the substrate. The touch layer includes a plurality of touch units on the foldable region of the substrate. The cover window layer is disposed on the touch layer, wherein the cover window layer includes a plurality of patterns disposed on the foldable region of the substrate. At least one of the plurality of touch units partially overlaps with at least one of the plurality of patterns of the cover window layer.
1. A touch display device, comprising:
a substrate including a foldable region;
a display layer disposed on the substrate;
a touch layer including a plurality of touch units on the foldable region of the substrate; and
a cover window layer disposed on the touch layer, wherein the cover window layer includes a plurality of patterns disposed on the foldable region of the substrate,
wherein at least one of the plurality of touch units partially overlaps with at least two of the plurality of patterns of the cover window layer, and the at least one of the plurality of patterns is directly touchable from outside.
2. The touch display device as claimed in claim 1 , wherein the plurality of patterns are protrusions.
3. The touch display device as claimed in claim 1 , wherein the plurality of patterns are recesses.
4. The touch display device as claimed in claim 1 , wherein the at least one of the plurality of patterns has a profile in a cross-sectional view, and at least a part of the profile is curved.
5. The touch display device as claimed in claim 1 , wherein two adjacent patterns of the plurality of patterns are spaced from a spacing distance, and the spacing distance is less than a width of one of the two adjacent patterns of the plurality of the patterns.
6. The touch display device as claimed in claim 1 , wherein the at least one of the plurality of touch units includes an opening and a touch enclosing part enclosing the opening.
7. The touch display device as claimed in claim 1 , wherein the cover window layer further includes a base layer disposed between the touch layer and the plurality of patterns.
8. The touch display device as claimed in claim 1 , wherein an edge of one of the plurality of patterns is touched by a touch object.
9. A touch display device, comprising:
a substrate including a foldable region;
a display layer disposed on the substrate;
a touch layer including a plurality of touch units on the foldable region of the substrate; and
a cover window layer disposed on the touch layer, wherein the cover window layer includes a plurality of patterns disposed on the foldable region of the substrate,
wherein an area of at least one of the plurality of touch units is greater than an area of at least one of the plurality of patterns in a top view, and the at least one of the plurality of patterns is directly touchable from outside.
10. The touch display device as claimed in claim 9 , wherein the plurality of patterns are protrusions.
11. The touch display device as claimed in claim 9 , wherein the plurality of patterns are recesses.
12. The touch display device as claimed in claim 9 , wherein the at least one of the plurality of patterns has a profile in a cross-sectional view, and at least a part of the profile is curved.
13. The touch display device as claimed in claim 9 , wherein two adjacent patterns of the plurality of patterns are spaced from a spacing distance, and the spacing distance is less than a width of one of the two adjacent patterns of the plurality of the patterns.
14. The touch display device as claimed in claim 9 , wherein the at least one of the plurality of touch units includes an opening and a touch enclosing part enclosing the opening.
15. The touch display device as claimed in claim 9 , wherein the cover window layer further includes a base layer disposed between the touch layer and the plurality of patterns.
16. The touch display device as claimed in claim 9 , wherein an edge of one of the plurality of patterns is touched by a touch object.
