Patent ID: 7196696

Claim:
A method of arranging the resistive sensing circuit on a position touch screen panel, comprising the steps of: arranging the resistive sensing circuit, consisting of sensor lines (Xin), (Xout), (Yin), and (Yout), on two substrates ( 11 , 12 ) in a way that allows the two substrates to be symmetrically overlapped, such that each substrate has two sensor lines in an X or a Y direction; and making parallel connections along the path of the sensor lines, (Xin), (Xout), (Yin), and (Yout), such that at least one pair of parallel connections in opposite corners (on diagonal lines) of the touch screen panel is able to attain matching voltages; wherein the pair of parallel connections in opposite corners (on diagonal lines) to attain matching voltages shall fulfill the conditions: measured voltages from first corner connections of sensor lines are high, and measured voltages from second corner connections of sensor lines are low, whereby the first and second corner connections respectively exist in diagonal opposite corners of the touch screen panel, and voltage levels at corner points are defined relative to other corner points on one sensor line, not from comparison of two sensor lines.
