Position-sensing panel and method

An exemplary touch position sensing panel includes an opaque electrode layer and a transparent electrode layer separated from the opaque electrode layer by a substrate. The electrodes are arranged such that nodes are formed in areas where the electrodes cross over each other. The transparent electro...

Zusammenfassung:An exemplary touch position sensing panel includes an opaque electrode layer and a transparent electrode layer separated from the opaque electrode layer by a substrate. The electrodes are arranged such that nodes are formed in areas where the electrodes cross over each other. The transparent electrode layer shields the opaque layer from electric field noise from electric field sources underlying the position-sensing panel, such as a display, while at the same time providing transparency to light emitted from the underlying display. Techniques are also discussed for forming the transparent electrode layer and/or the opaque electrode layer.
