Claim 14:
15. The touch detecting method according to claim 14, wherein, at least one path switch is provided between output terminals of every two output stage circuits included in each output module,
the controlling utilizing the power from the first driving electrode group to charge the second driving electrode group, further comprises:
in the first time period, disabling, by the controller, the first output stage circuit group and the second output stage circuit group, and controlling 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, enabling, by the controller, a conductive path between the output terminal of the first output stage circuit group and the low-level power supply terminal as well as a conductive path between the high-level power supply terminal and the output terminal of the second output stage circuit group, and controlling turning off the at least part of the at least one path switch.
