The present invention discloses a touch display panel and a driving method thereof, and a touch display device. The touch display panel comprises a driving scanning circuit and m touch driving electrode units; the ith touch driving electrode unit includes ni touch driving electrodes, and the ni touch driving electrodes are divided into at least two touch driving electrode sets; the driving scanning circuit includes m driving circuit units and a shifting register with n cascaded shifting register unit; the kth touch driving electrode in each touch driving electrode unit is connected with the k-grade shifting register unit through the driving control unit, wherein the m and the ni are the integers of larger than 1, 1<=i<=m, the n is the maximum value in the ni, and the k is the positive integer of not larger than ni. According to the scheme, the touch display panels are divided into a plurality of touch driving electrode units, and each touch driving electrode unit uses the same shifting register so as to reduce the series of the shifting register unit and facilitate the realization of the narrow bezel.
