Abstract

A single-layer mutual capacitive touch panel operable under control of a controller is provided. The mutual capacitive touch panel includes a first driving electrode, a second driving electrode, N number of first receiving electrodes surrounding the first driving electrode, M number of second receiving electrodes surrounding the second driving electrode, a driving channel, and (N+M) number of receiving channels. The controller simultaneously sends a driving signal to the first driving electrode and the second driving electrode via the driving channel. When sending the driving signal, the controller receives (N+M) number of sensing results via the (N+M) number of receiving channels. The N number of first receiving electrodes and the M number of second receiving electrodes correspond to different receiving channels.

First claim

What is claimed is:

1. A single-layer mutual capacitive touch panel, operable under control of a controller, comprising:
a first driving electrode;
a second driving electrode;
N number of first receiving electrodes, surrounding the first driving electrode, each side of the first driving electrode corresponding to one of the first receiving electrodes;
M number of second receiving electrodes, surrounding the second driving electrode, each side of the second driving electrode…
