Abstract
In one embodiment, an method apparatus includes an optically clear adhesive (OCA) layer between a cover sheet and a substrate. The substrate has drive or sense electrodes of a touch sensor disposed on a first surface and a second surface of the substrate. The first surface is opposite the second surface and the drive or sense electrodes are made of a conductive mesh of conductive material including metal.
Claims15
An apparatus comprising:
- a first optically clear adhesive (OCA) layer between a first cover sheet and a substrate;
- the substrate, with drive or sense electrodes of a touch sensor disposed on a first surface and a second surface of the substrate, the first surface being opposite the second surface, the drive or sense electrodes being made of a conductive mesh conductive material comprising metal;
- and
- a display separated from the second surface of the substrate by a second OCA and a second cover sheet such that at least a portion of the second cover sheet is positioned between the second surface of the substrate and the display.
