Claim 1:
2. The touch driving circuit according to claim 1, wherein the switching circuit is further configured to control the touch electrode to be connected to the second energy storage capacitor during a sixth period of time, the second energy storage capacitor being configured to store the charges released by the touch electrode, so that the voltages at the two ends of the touch electrode is equal to the second negative voltage; control the touch electrode to be connected to the ground terminal GND during a seventh period of time, the touch electrode being discharged to the ground terminal GND, so that the voltage at the two ends of the touch electrode is equal to the zero voltage; and control the touch electrode to be connected to the first energy storage capacitor during an eighth period of time, the first energy storage capacitor being configured to transfer the stored charges to the touch electrode, so that the voltage at the two ends of the touch electrode is equal to the second positive voltage.
