Abstract

A capacitor-type touch panel using a single-layer sensor to implement a two-dimensional application comprises: a controller, a plurality of scanning lines, and a plurality of sensing electrodes distributed on the single-layer sensor. Each sensing electrode is connected to the controller through a scanning line for sending its sensed value to the controller. To position a touched position, the controller selects one or some of the sensing electrodes as reference point(s) to perform an interpolation calculation, thereby generating a two dimensional coordinate of the touched position.
