Patent ID: 8004500

Claim:
A single-surface touch sensor panel, comprising: a plurality of distributed RC lines arranged in an array of rows and columns, the distributed RC lines including alternating connected transistors and metal pads formed on a single surface of a sensor panel substrate, each transistor having drain and source terminals connected to adjacent metal pads; first and second column gate signal lines connected to gate terminals of the transistors on either side of each metal pad arranged in a column; and first and second row gate signal lines connected to the gate terminals of the transistors on either side of each metal pad arranged in a row; wherein the first and second column gate signal lines are configured for receiving non-overlapping first and second column gate signals to alternately gate the transistors in each column on and off and provide an effective resistance for each column; and wherein the first and second row gate signal lines are configured for receiving non-overlapping first and second row gate signals to alternately gate the transistors in each row on and off and provide an effective resistance for each row.
