Claim:
1. A touch panel with a single-layer low-complexity transparent electrode pattern, comprising: a substrate; N sensing units, formed on the substrate, each sensing unit comprising a conductive resistance trace and a sensing electrode, each of the conductive resistance traces having a specific and unique impedance value and being connected with the sensing electrodes of two neighboring sensing units, any one of the sensing electrodes being connected with at least another one sensing electrode through at least one conductive resistance trace, such that the sensing units are connected in series and each of sensing units has a resistor-capacitor time constant different from that of the other sensing units, where N is a positive integer, wherein N driving signals with different frequencies are sequentially applied to the N sensing units via one of the N sensing units to measure capacitance changes of the N sensing units thereby determining if there is at least one of the N sensing units touched.
