1. A touch panel, comprising:
at least one touch sensing unit set, wherein the touch sensing unit set includes at least two touch sensing units, wherein one of the two touch sensing units is presented in a positive L shape, and the other is presented in an inverted L shape, the two touch sensing units are presented in a rectangular-like shape;
at least one driving signal line set, wherein the driving signal line set includes at least two driving signal lines, one of the driving signal lines in the driving signal line set is electrically connected to one of the touch sensing units in the touch sensing unit set; and
at least one touch circuit, the touch circuit corresponding to the driving signal line set; wherein the touch circuit includes at least two switching thin film transistors, gates of the switching thin film transistors in the touch circuit are connected to each other, sources/drains of the switching thin film transistors in the touch circuit are connected to each other, and the drain/source of one of the switching thin film transistors in the touch circuit is electrically connected to one corresponding driving signal line;
wherein outlines of two adjacent touch sensing units are partially staggered, and the number of the touch sensing units in at least one row in the touch sensing unit set is different from the number of the touch sensing units in the other rows.
