Abstract

A multi-touch sensing panel for a display screen comprising a panel including a plurality of electrically isolated conductors crossing each other at a plurality of intersection points, for use with a touch detector. The touch detector is arranged to detect a user touch by detecting a reduction in energy transferred by capacitive coupling between the conductors that cross at the intersection points, a reduction in capacitively coupled energy detected in a vicinity of a given intersection corresponding to a user touch detected in the vicinity of that intersection point. Each of the plurality of electrically isolated conductors comprises a conducting wire following a non-linear continuous path between a pair of intersection points and each non linear path includes a plurality of straight sections with a direction different from the directions between adjacent pairs of intersection points, such that when the directions between adjacent pairs of intersection points are aligned with pixel repeat directions of a pixel array of the display, visible Moiré interference with the pixel display is diminished, and at least some of the straight sections between adjacent pairs of intersection points are substantially parallel with each other.
