Abstract
A touch scanning circuit and a driving method thereof, a touch driving circuit and a display panel. The touch scanning circuit includes: an input sub-circuit, a first control sub-circuit, a second control sub-circuit, a shift output sub-circuit and a touch output sub-circuit. The input sub-circuit is configured to control a potential of a first node; the first control sub-circuit is configured to control connection and disconnection between the first node and a third node; the second control sub-circuit is configured to control a potential of a second node; the shift output sub-circuit is configured to control a potential of a shift output end according to the third node and the second node; and the touch output sub-circuit is configured to control a signal outputted from a touch output end according to the second node, the shift output end and the first clock signal end.
