1. A touch panel comprising a touch region and a binding region located on one side of a first direction of the touch region; wherein the touch region comprises n touch sub-regions disposed sequentially along a second direction, and at least one of the touch sub-regions comprises a plurality of touch electrodes and a plurality of touch traces; the binding region comprises a trace lead-out region adjacent to the touch region, and the trace lead-out region comprises n lead convergence regions disposed sequentially along the second direction; first ends of a plurality of touch traces in an i-th touch sub-region are connected respectively to a plurality of touch electrodes in the i-th touch sub-region, and second ends of the plurality of touch traces in the i-th touch sub-region extend to an i-th lead convergence region of the trace lead-out region; in the first direction, the i-th lead convergence region does not overlap with other touch sub-regions except the i-th touch sub-region, or other lead convergence regions except the i-th lead convergence region do not overlap with the i-th touch sub-region; wherein n is a positive integer greater than 2, i=1, 2, . . . , n, and the second direction crosses the first direction;
wherein the i-th lead convergence region comprises a plurality of fold lines, which are configured to be electrically connected to the plurality of touch traces in the i-th touch sub-region and converge together to form the i-th lead convergence region; convergence directions of the fold lines in the n lead convergence regions are asymmetric with respect to a center line extending along the first direction in the trace lead-out region.
