A position touch screen panel using a pattern of arranging the resistive sensing circuit, in which the touch screen panel is formed by two substrates (11, 12) symmetrically overlapped, having four sensor lines extending along the periphery of the substrates (11,12) and creating parallel connections to cov er four corners, such that at least one pair of parallel connections in opposit e corners (on diagonal corners) shall attain matching voltages. The matching voltages is realized only if high voltage is measured from parallel connections at one corner; and low voltage is measured from parallel connections in an opposite corner; whereby voltage levels at corner points are defined relativ e to other corner points on one sensor line, not from comparison of two sensor lines. Using the arrangement, the touch screen panel is able to determine the tou ch position accurately.
