CAPACITIVE TOUCH PANEL AND ELECTRODE SET THEREOF

摘要

A capacitive touch panel has multiple electrode couples formed on a substrate. Each electrode couple has multiple first electrodes and multiple second electrodes. Each of the first electrode and the second electrode has three traces. Each end of one of the three traces is connected to one end of one of the other two traces. The three traces of the first electrode and the three traces of the second electrode are alternately arranged. Given the foregoing layout of the electrode couples, the first electrodes and the second electrodes have symmetrical capacitance values and resistance values. Accordingly, the capacitive touch panel has an enhance signal-to-noise ratio and an anti-interference capability.
