Abstract
A scanning circuit, a driver circuit, a touch display panel, a receiving switching circuit and a driving method are disclosed. The scanning circuit includes a function switching circuit and a plurality of shift register units that are cascaded. Each shift register units includes a control terminal and a shift scanning output terminal, and is configured to output a first output signal at the shift scanning output terminal; the function switching circuit includes a mode switching input terminal, a control signal output terminal and a mode scanning output terminal, and the control signal output terminal and the mode scanning output terminal are respectively connected to the control terminals and the shift scanning output terminals of the plurality of shift register units. The function switching circuit is configured to output the control signal to the control terminals or to output a second output signal to the shift scanning output terminals.
