MULTI-TOUCH SENSING ARRANGEMENT

摘要

A multi-touch sensing panel arrangement for a display screen comprising a panel including a plurality of electrically isolated conductors crossing each other at a plurality of intersection points and 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 at a given intersection corresponding to a user touch detected at that intersection point. Each of the plurality of electrically isolated conductors comprise a conducting wire individually insulated with an insulating coating.
