Projected capacitive touch-sensitive panel

A touch-sensitive panel, comprising:

• a first plurality of sense electrodes that are formed from a first layer of substantially transparent resistive material and that extend in a first direction;
• and
• a second plurality of sense electrodes and at least one shield electrode that are formed from a second layer of substantially transparent resistive material and that extend in a second direction;
• wherein each sense electrode is operable to generate an electrostatic field used in sensing touch events and wherein the at least one shield electrode is operable to cancel parasitic capacitance between at least one sense electrode in the first plurality of sense electrodes and at least one sense electrode in the second plurality of sense electrodes.

A method for operating a touch-sensitive panel comprising:

• charging a first plurality of sense electrodes disposed upon and extending in a first direction across a first substrate surface to generate an electrostatic field around each of the first plurality of sense electrodes for use in sensing touch events;
• charging a second plurality of sense electrodes disposed upon and extending in a second direction across a second substrate surface to generate an electrostatic field around each of the second plurality of sense electrodes for use in sensing the touch events;
• and
• charging at least one shield electrode disposed upon the second substrate surface in a manner that cancels parasitic capacitance between at least one of the first plurality of sense electrodes and at least one of the second plurality of sense electrodes.
