Abstract
A capacitance touch device includes a touch panel, a plurality of triangular sensing pads, a plurality of conducting wires, and a control circuit. Every four triangular sensing pads are arranged forming a square deposited on the touch panel. Each triangular sensing pad is corresponding to a location and is electrically connected to the control circuit through one conducting wire. When the plurality of triangular sensing pads is touched generating sensing signals, the control circuit can calculate the location of the touch point according to the intensity of the sensing signals.
