Abstract

A touch display device is provided and includes a substrate, a plurality of light-emitting units, and a plurality of touch electrodes. The substrate includes a first edge. The light-emitting units are disposed on the substrate. The touch electrodes are disposed on the light-emitting units. A first distance is a minimum distance from the first edge to the light-emitting units parallel to the substrate, a second distance is a minimum distance from the first edge to the touch electrodes parallel to the substrate, and the first distance is greater than the second distance.

Claims (27)

1. A touch display device comprising:

a substrate comprising a first edge;

a plurality of light-emitting units disposed on the substrate;

a plurality of touch electrodes disposed on the light-emitting units;

an insulation layer disposed between the light-emitting units and the touch electrodes;

a touch trace; and

a wire layer electrically connected to the touch electrodes;

wherein a first distance is a minimum distance from the first edge to the light-emitting units parallel to the substrate, a second distance is a minimum distance from the first edge to the touch electrodes parallel to the substrate, and the first distance is greater than the second distance;

wherein the touch trace is electrically connected to one of the touch electrodes, and the touch trace contacts the substrate and the insulation layer;

wherein the insulation layer has a plurality of protrusions, and the wire layer is disposed on the protrusions.

2. The touch display device of claim 1 , wherein a third distance is a minimum distance from the first edge to the insulation layer parallel to the substrate, and the third distance is less than the second distance.

3. The touch display device of claim 2 , wherein a portion of the insulation layer disposed between the light-emitting units and the touch trace.

4. The touch display device of claim 1 , wherein the wire layer does not overlap the light-emitting units in a direction perpendicular to the substrate.

5. The touch display device of claim 1 , wherein a third distance is a minimum distance from the first edge to the insulation layer parallel to the substrate, and the third distance is greater than the second distance.

6. The touch display device of claim 1 , wherein the substrate further comprises a second edge, a fourth distance is a minimum distance from the second edge to the light-emitting units parallel to the substrate, a fifth distance is a minimum distance from the second edge to the touch electrodes parallel to the substrate, and the fourth distance is less than the fifth distance.

7. The touch display device of claim 1 , wherein the light-emitting units have a display region in a direction perpendicular to the substrate, and the touch electrodes have a touch region in the direction perpendicular to the substrate.

8. The touch display device of claim 7 , wherein the display region is disposed in the touch region in the direction perpendicular to the substrate.

9. The touch display device of claim 7 , wherein the display region has a first area, the touch region has a second area, and the first area is less than the second area.

10. The touch display device of claim 7 , wherein the touch region comprises a first touch region, a second touch region and a non-touch region, the non-touch region is between the first touch region and the second touch region, a portion of the touch electrodes is disposed in the first touch region, and another portion of the touch electrodes is disposed in the second touch region.

11. The touch display device of claim 10 , wherein the non-touch region separates the first touch region from the second touch region.

12. The touch display device of claim 10 , wherein the first touch region has a first side and a second side, the first side faces the second touch region, and the first side and the second side are connected to each other, and wherein the first side and the second side have an included angle less or greater than 90 degrees.

13. The touch display device of claim 10 , further comprising a plurality of first touch wires connected to the portion of the touch electrodes in the first touch region and a plurality of second touch wires connected to the another portion of the touch electrodes in the second touch region.

14. The touch display device of claim 10 , further comprising a connecting wire overlapping the non-touch region in the direction perpendicular to the substrate.

15. The touch display device of claim 14 , wherein the connecting wire electrically connects one of the touch electrodes in the first touch region and one of the touch electrodes in the second touch region.

16. The touch display device of claim 10 , wherein the substrate has a bent portion and a flat portion, and the bent portion corresponds to the non-touch region.

17. The touch display device of claim 16 , wherein the insulation layer comprises a first portion corresponding to the bent portion and a second portion corresponding to the flat portion, the first portion has a maximum thickness, the maximum thickness of the first portion is a first thickness, the second portion has a maximum thickness, the maximum thickness of the second portion is a second thickness greater than or equal to the first thickness.

18. The touch display device of claim 16 , wherein the light-emitting units correspond to the flat portion.
