    Abstract

    We have devised a method that employs surface- and self-capacitive sensing principles for touch detection with a single-layered capacitive touch panel. In this method, a single electrode layer consisting of a stripe-shaped one-dimensional electrode array was used to enable multi-touch detection, and a capacitive sensing circuit that uses a trans-impedance amplifier was selected to simplify the circuit structure of the touch panel. The results indicate that the number of the panel fabrication processes and the amount of the touch electrode material required can be reduced by half by using the proposed method.
