Abstract

A display apparatus includes a display panel including a display area and a non-display area at least partially surrounding the display area; a touch electrode on the display panel and including an electrode metal having a mesh shape; and a plurality of touch routing lines at an outside of the touch electrode and electrically connected to the touch electrode, and the touch electrode is in the display area and a part of the non-display area, and a width of the electrode metal of the touch electrode in the non-display area is different from a width of the electrode metal of the touch electrode in the display area.

Claims (25)

1. A display apparatus, comprising:

a display panel including a display area having a plurality of pixels and a non-display area that at least partially surrounds the display area;

a touch electrode on the display panel, the touch electrode including an electrode metal having a mesh shape including a plurality of openings;

a plurality of touch routing lines at an outside of the touch electrode in the non-display area, the plurality of touch routing lines electrically connected to the touch electrode,

wherein the touch electrode includes a first touch electrode part in the display area and a second touch electrode part in the non-display area that extends from the first touch electrode part in the display area,

wherein a second opening of the electrode metal of the second touch electrode part that is in the non-display area is non-overlapping with any one of the plurality of pixels and a first opening of the electrode metal of the first touch electrode part that is in the display area overlaps a pixel from the plurality of pixels.

2. The display apparatus of claim 1 , wherein a width between second adjacent openings of the electrode metal of the second touch electrode part that are in the non-display area increases toward an outside of the non-display area.

3. The display apparatus of claim 2 , wherein the width of the electrode metal is increased by a same width in every predetermined section of the non-display area.

4. The display apparatus of claim 3 , wherein the predetermined section has a square shape or a partial annular sector shape.

5. The display apparatus of claim 1 , wherein widths of some of the plurality of touch routing lines are different from each other.

6. The display apparatus of claim 5 , wherein a width of an outermost touch routing line among the plurality of touch routing lines has a largest width amongst the plurality of touch routing lines.

7. The display apparatus of claim 6 , wherein the outermost touch routing line has a crescent shape.

8. The display apparatus of claim 1 , wherein each of the plurality of pixels includes an organic light emitting diode.

9. A display apparatus, comprising:

a display panel including a display area and a non-display area at least partially surrounding the display area, the display area having a rounded shape;

a touch electrode on the display panel, the touch electrode including an electrode metal having a mesh shape; and

a plurality of touch routing lines at an outside of the touch electrode, the plurality of touch routing lines electrically connected to the touch electrode,

wherein the touch electrode is in the display area and a part of the non-display area,

wherein a width of an outermost touch routing line among the plurality of touch routing lines is different from widths of remaining touch routing lines of the plurality of touch routing lines,

wherein some portions of the touch electrode include an opening, and an outermost portion of the touch electrode in the non-display area lacks the opening.

10. The display apparatus of claim 9 , wherein the width of the outermost touch routing line among the plurality of touch routing lines has a largest width amongst the plurality of touch routing lines.

11. The display apparatus of claim 10 , wherein the outermost touch routing line has a crescent shape.

12. The display apparatus of claim 9 , wherein a width of the electrode metal of the touch electrode in the non-display area surrounding a comer portion of the display area increases toward an outside of the non-display area.

13. The display apparatus of claim 12 , wherein the width of the electrode metal of the touch electrode disposed in the non-display area surrounding the comer portion of the display area increases by a same width in every predetermined section of the non-display area.

14. The display apparatus of claim 13 , wherein in the predetermined section, the touch electrode has a shape in which a plurality of partial annular sectors whose radius is gradually increased is continuously disposed.
