Claim 2:
3. The touch driving apparatus according to claim 2, further comprising: at least one path switch provided between output terminals of every two output stage circuits in the at least two output stage circuits,
wherein, in the first time period, the controller disables the first output stage circuit group and the second output stage circuit group, and controls turning on at least part of the at least one path switch, so that the power from the first driving electrode group charges the second driving electrode group; and
after the first time period, the controller enables a conductive path between the output terminal of the first output stage circuit group and a low-level power supply terminal as well as a conductive path between a high-level power supply terminal and the output terminal of the second output stage circuit group, and controls turning off the at least part of the at least one path switch.
