Abstract
The present invention discloses an inverting circuit, a driving method thereof, a touch display panel and a touch display device. The inverting circuit includes an input module and an output module, the input module is used for controlling a potential of the first node, and the output module is used for controlling, under the control of the potential of the first node, an output signal of the first output terminal according to input signals of the first input terminal, the third voltage terminal and the third signal terminal. In the technical solutions provided by the present invention, a light-emitting control signal is switched off in a touch stage by means of time-sharing driving to lower the capacitance to ground of the touch electrode, so that resistive and capacitive load of the touch electrode is reduced, touch driving frequency is increased, and touch accuracy is thus improved.
