A driving circuit and method for a touch panel having a plurality of scan lines includes a detection module, an interruption module and a selective scan module. The detection module can periodically scan the scan lines, so as to detect whether the touch panel is controlled by touch. The interruption module can turn off the detection module when the touch panel is not controlled by touch. The selective scan module can select at least one set of scan lines from the plurality of scan lines to periodically and synchronously scan the set of selected scan lines when the detection module is turned off, where scanning of the selected scan lines detects whether the touch panel is touched.
