Abstract
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.

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;
- a touch detector, said touch detector 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 point corresponding to a user touch detected at that intersection point;
- and
- wherein each of the plurality of electrically isolated conductors comprise a conducting wire individually insulated with an insulating coating.
A multi-touch sensing display comprising:
- a multi-touch sensing panel including a plurality of electrically isolated conductors crossing each other at a plurality of intersection points;
- a display screen positioned relative to the multi-touch sensing panel;
- a touch detector, said touch detector 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 of the multi-touch sensing panel, a reduction in capacitively coupled energy detected at a given intersection point corresponding to a user touch detected at that intersection point, said touch detector arranged to generate multi-touch data for controlling the display screen based on the detected user touch;
- and
- wherein each of the plurality of electrically isolated conductors of the multi-touch sensing panel comprise a conducting wire individually insulated with an insulating coating.
