Claim:
1. A touch panel, comprising: a driving line configured to transmit a driving signal; a gate line configured to transmit a scan signal; a readout line, forming a mutual capacitance with the driving line, the mutual capacitance being configured to generate a first sensing signal in response to a driving signal according to a touch operation; a switching unit electrically coupled to the gate line and the readout line, and configured to be selectively turned on to transmit the first sensing signal to the readout line according to the scan signal; and an amplifying unit configured to generate a second sensing signal according to the first sensing signal, and the switching unit being further configured to transmit the second sensing signal to the readout line, wherein the amplifying unit comprises: wherein a second terminal of the driving switch is configured to receive the second control signal.
