TOUCH DISPLAY PANEL, DRIVING METHOD THEREOF AND TOUCH DISPLAY DEVICE
First Claim
1. A touch display panel comprising:
- a base substrate, a plurality of touch electrode blocks in an array disposed on the base substrate, a plurality of touch wires and a touch control chip, each of the touch electrode blocks being electrically connected to the touch control chip through one of the touch wires, and the touch display panel further comprising at least one switching transistor, a storage capacitor, a first control chip and a second control chip, whereinthe 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 other end of the storage capacitor is connected to the second control chip;
the first control chip is configured to, before switching to a touch detection period, output a first control signal to control the switching transistor to be turned off, and when switching to a display period, output a second control signal to control the switching transistor to be turned on; and
the second control chip is configured to, before switching to the touch detection period, output a charging signal to charge the storage capacitor, such that the storage capacitor has a preset voltage.
