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;

    M number of second receiving electrodes, surrounding the second driving electrode;

    a driving channel, through which the controller simultaneously sends a driving signal to the first driving electrode and the second driving electrode; and

    (N+M) number of receiving channels, respectively corresponding to one of the N number of first receiving electrodes and the M number of second receiving electrodes;

    wherein, the N number of first receiving electrodes and the M number of second receiving electrodes respectively correspond to different receiving channels, the controller receives (N+M) number of sensing results via the (N+M) number of receiving channels when sending the driving signal, and N and M are positive integers.
