Abstract

A touch user interface may be implemented at a display edge, such as a display included with a portable information handling system. An edge touch element may provide structural support for the display along with touch functionality. The edge touch element may be integrated with a touch panel included with the display. The edge touch element may wrap around to a back face of the display.

Claims

1. An edge touch element for portable information handling systems, comprising:

a touch sensor layer bonded to a first edge of a display included in a portable information handling system; and

wherein the first edge is an external edge that is perpendicular to a display surface of the display; and

wherein the touch sensor layer includes a plurality of touch pixels that are individually sensitive to touch input.

2. The edge touch element of claim 1, wherein the display includes a touch panel layer that coincides with the display surface.

3. The edge touch element of claim 2, wherein the edge touch element is electronically integrated with the touch panel layer.

4. The edge touch element of claim 3, wherein the touch sensor layer and the touch panel layer have a common touch pixel coordinate axis.

5. The edge touch element of claim 1, wherein the touch sensor layer extends to a back surface of the display opposite the display surface.

6. The edge touch element of claim 1, wherein the touch sensor layer extends to a second edge of the display that is perpendicular to the display surface.

7. The edge touch element of claim 6, wherein the touch sensor layer extends to a third edge of the display that is perpendicular to the display surface.

8. The edge touch element of claim 1, wherein the touch sensor layer includes portions having non-uniform touch pixel density.

9. The edge touch element of claim 1, wherein the touch sensor layer includes portions having different sensitivity to touch input.

10. The edge touch element of claim 1, wherein the touch sensor layer includes portions having different thicknesses.

11. An information handling system comprising:

an edge touch element bonded to a first edge of a display included in the information handling system, the edge touch element further comprising a touch sensor layer;

wherein the first edge is an external edge that is perpendicular to a display surface of the display; and

wherein the touch sensor layer includes a plurality of touch pixels that are individually sensitive to touch input.

12. The information handling system of claim 11, wherein the touch sensor layer extends to a back surface of the display opposite the display surface.

13. The information handling system of claim 11, wherein the touch sensor layer extends to a second edge of the display that is perpendicular to the display surface.

14. The information handling system of claim 11, wherein the touch sensor layer extends to a third edge of the display that is perpendicular to the display surface.

15. The information handling system of claim 11, wherein the touch sensor layer includes portions having non-uniform touch pixel density.

16. The information handling system of claim 11, wherein the touch sensor layer includes portions having different sensitivity to touch input.

17. The information handling system of claim 11, wherein the touch sensor layer includes portions having different thicknesses.

18. The information handling system of claim 11, further comprising:

a structural element including the touch sensor layer at the first edge, wherein the structural element holds together components comprising the display.

19. The information handling system of claim 11, wherein the edge touch element further comprises:

a conductive trace coupled to electronic components of the information handling system, wherein the conductive trace is electronically isolated from the touch sensor layer.

20. The information handling system of claim 19, wherein the conductive trace includes an antenna for radio frequencies.
