Claim 8:
9. The touch driving apparatus according to claim 2, wherein, each output stage circuit comprises a first switch and a second switch connected in series between a high-level power supply terminal and a low-level power supply terminal; and a connection node of the first switch and the second switch is connected to an output terminal of the output stage circuit;
the controller controls turning off the first switch and the second switch of each output stage circuit in the first output stage circuit group and the second output stage circuit group within the first time period; and
after the first time period, the controller controls turning on the first switch and turning off the second switch of each output stage circuit in the second output stage circuit group, to utilize power from the high-level power supply terminal to charge the driving electrode connected to the output stage circuit via the first switch, and controls turning on the second switch and turning off the first switch of each output stage circuit in the first output stage circuit group, to release remaining power from the driving electrode connected to the output stage circuit to the low-level power supply terminal via the second switch.
