Capacitive touch screen including a first sensor pattern for mutual sensing and a second sensor pattern for self sensing

A capacitive touch panel apparatus, comprising:

• a first layer of patterned conductive material forming a plurality of rows of electrically connected sensor nodes;
• a second layer of patterned conductive material forming a plurality of columns of electrically connected sensor nodes;
• a third layer of pattered conductive material forming a plurality of conductive islands;
• wherein each sensor node includes a central opening;
• and
• wherein each conductive island is positioned in vertical alignment with the central open region of a corresponding sensor node.

An apparatus, comprising:

• a capacitive touch panel including:
• a mutual-capacitance sensor pattern including a plurality of row conductors and a plurality of column conductors;
• and
• a self-capacitance sensor pattern including a plurality of clusters of conductive islands, each cluster including two or more conductive islands electrically connected by one or more conductor lines;
• wherein said mutual-capacitance and self-capacitance sensor patterns are supported by a support substrate one pattern on top of the other pattern.
