Abstract

A touch panel connected with p signal channels of a chip is provided. The touch panel includes a substrate, electrode pairs, and signal lines. The electrode pairs are arranged in a matrix of q columns and r rows and each includes a first electrode connected to the h th signal channel and a second electrode connected to the i th signal channel. The h th signal channel and the i th channel are served as a signal channel pair. The signal channel connected with the electrode pair arranged in the j th column of the k th row is different from the signal channel connected with the other electrode pairs. The signal lines are electrically connected between the first electrodes or the second electrodes to the corresponding signal channels.

First claim

What is claimed is:

1. A touch panel connected to p signal channels of a chip, the touch panel comprising:
a substrate;
a plurality of electrode pairs, disposed on the substrate and arranged in a matrix of q columns and r rows, wherein p, q, and r are respectively a positive integer, and each of the electrode pairs comprises:
a first electrode and a second electrode respectively connected to a h th signal channel and an i th signal channel of the chip, the h th signal chann…
