Sensing circuit and sensing method

A sensing circuit, comprising:

• a plurality of first transceiver channels, configured to send and receive a plurality of first detection signals, and the plurality of first detection signals are independent of each other;
• and
• a plurality of second transceiver channels, configured to send and receive a plurality of second detection signals, and the plurality of second detection signals are independent of each other, wherein the plurality of first transceiver channels and the plurality of second transceiver channels are alternately arranged to form an array,
• wherein during a self-capacitance mode, each of the plurality of first transceiver channels and the plurality of second transceiver channels are configured to output and receive a corresponding one of a plurality of self-capacitance sensing signals,
• wherein during a mutual-capacitance mode, the plurality of first transceiver channels are configured to output a plurality of mutual-capacitance sensing signals, and the plurality of second transceiver channels are configured to receive the plurality of mutual-capacitance sensing signals,
• wherein the first transceiver channels and the second transceiver channels output and receive the corresponding one of the plurality of self-capacitance sensing signals during the self-capacitance mode and the first transceiver channels and the second transceiver channels respectively output and receive the mutual-capacitance sensing signals in the mutual-capacitance mode, a touch signal is determined as a signal triggered by a finger if both the plurality of self-capacitance sensing signals and the plurality of mutual-capacitance sensing signals are received from the array, and the touch signal is determined as a noise or a deformation-triggered signal representing a change of an air gap between panels if only the plurality of self-capacitance sensing signals are received from the array;
• and
• wherein the touch signal is calibrated or drop frame when the touch signal is determined as the noise signal or the deformation-triggered signal.
