Abstract
A touch display panel, a driving method thereof and a touch display device are disclosed. The touch display panel includes a base substrate, a plurality of touch electrode blocks in an array disposed on the base substrate, and touch wires, and further includes a switching transistor, a storage capacitor, a first control chip and a second control chip. The switching transistor has a gate electrode connected to the first control chip, a source electrode connected to an end of the storage capacitor and a drain electrode connected to the touch electrode block; the first control chip is configured to output a first control signal to control the switching transistor to be turned off, and output a second control signal to control the switching transistor to be turned on; and the second control chip is configured to output a charging signal to charge the storage capacitor.
