Abstract
A high-accuracy single-layer capacitive touch panel device with one side for connection includes a substrate, a plurality of conductive lines, and a touch detection circuit. The conductive lines are 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 includes a conductive trace having opposite first edge and second edge and a plurality of triangle sensing electrodes arranged at the two edges of the conductive trace. Each triangle sensing electrode is connected with the conductive trace via a connection part. Each conductive line only has one connection end close to the second side. A touch detection circuit is 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.
