1. A flexible display panel, comprising:
a first frame region comprising an upper left region and a lower left region, wherein the upper left region is independent from the lower left region;
a second frame region comprising an upper right region and a lower right region, wherein the upper right region is independent from the lower right region;
a bending axis located between the first frame region and the second frame region;
a display film layer; and
a mutual-capacitance touch film layer stacked on the display film layer, wherein the mutual-capacitance touch film layer comprises:
a sensing electrode system, comprising:
a plurality of first touch electrodes that extend in a first direction and that are arranged in a second direction extending along the bending axis; and
a plurality of second touch electrodes that extend in the first direction and that are arranged in the second direction, wherein the first touch electrodes and the second touch electrodes are in a one-to-one correspondence, wherein an extension direction of a first touch electrode and an extension direction of a corresponding second touch electrode are arranged in a straight line, and wherein the first touch electrode and the corresponding second touch electrode are spaced apart; and
an interval location between each first touch electrode and a corresponding second touch electrode located on the bending axis; and
a drive electrode system, comprising:
a plurality of fourth touch electrodes that extend in the second direction and that are arranged in the first direction, wherein one or more of the fourth third touch electrodes and each first touch electrode in the upper left region and the upper right region are insulated and crossed, and wherein one or more of the fourth third touch electrodes and each second touch electrode are in the upper left region and the upper right region insulated and crossed; and
a plurality of fifth touch electrodes that extend in the second direction and that are arranged in the first direction, wherein one or more of the fifth touch electrodes and each first touch electrode in the lower left region and the lower right region are insulated and crossed, and wherein one or more of the fifth touch electrodes and each second touch electrode in the lower left region and the lower right region are insulated and crossed.
