Claim:
1. A high-accuracy single-layer capacitive touch panel device with one side for connection, comprising: a substrate having a surface, a first side, and a second side opposite to the first side; a plurality of conductive lines, each having an equivalent resistance and an equivalent capacitance, the plurality of conductive lines being arranged in parallel on the surface of the substrate and extended from the first side to the second side of the substrate, each conductive line including a conductive trace having a first edge and a second edge opposite to the first edge, and a plurality of triangle sensing electrodes arranged at the two edges of the conductive trace, each triangle sensing electrode having a symmetry axis and being connected with the conductive trace via a connection part which is a conductor wire, wherein the conductive wire is extended along the symmetry axis of the triangle sensing electrode and has a width smaller than any of side lengths of the triangle sensing electrode, each conductive line only having one connection end close to the second side; and a touch detection circuit electrically connected to the connection ends of the plurality of conductive lines through a connection circuit, so as to detect variations of the equivalent resistances and the equivalent capacitances of the plurality of conductive lines, thereby determining at least one touch position on the substrate, wherein the plurality of triangle sensing electrodes at the first edge of the conductive trace of an i-th conductive line are disposed at positions aligned with those of the plurality of triangle sensing electrodes at the second edge thereof, respectively, and the symmetry axes of two adjacent triangle sensing electrodes at the first edge thereof are arranged to have a first distance therebetween, where i is a positive integer, the symmetry axis of one of the plurality of triangle sensing electrodes at the first edge of the conductive trace of the i-th conductive line is arranged at a position to have a second distance to the symmetry axis of a nearest one of the plurality of triangle sensing electrodes at the first edge of the conductive trace of the (i+1)-th conductive line, and the first distance is twice of the second distance, and the symmetry axis of one of the plurality of triangle sensing electrodes at the second edge of the conductive trace of the i-th conductive line is arranged at a position to have the second distance to the symmetry axis of a nearest one of the plurality of triangle sensing electrodes at the second edge of the conductive trace of the (i+1)-th conductive line.
