Claim 18:
19. A driving method for driving the display panel according to claim 18, the driving method comprising a plurality of frame periods each comprising a display scanning signal output phase and a detection scanning signal output phase, the driving method comprising:
controlling one of the pull-down control sub-circuits through the selection sub-circuit to provide a signal to the pull-down control terminal of the pull-down sub-circuit;
in the display scanning signal output phase of each frame period, providing a display trigger signal to the control terminal of the display signal input sub-circuit in the first stage of shift register unit of each shift register unit group, so as to provide a signal to the pull-up control terminal of the pull-up sub-circuit by using the display signal input sub-circuit;
in the display scanning signal output phase of the first frame period, providing a detection initial signal to the input terminal of the detection signal input sub-circuit in the first stage of shift register unit of each shift register unit group, so as to provide a signal to the pull-up control terminal of the pull-up sub-circuit by using the detection signal input sub-circuit, and in different frame periods, respectively controlling the detection signal input sub-circuits in different stages of shift register units to output, so that in a predetermined number of frame periods, each of the shift register units outputs a valid signal to the pull-up control terminal of the pull-up sub-circuit in the detection scanning signal output phase.
