1. A touch panel, having a first component region and a touch region, and comprising:
a plurality of first-type touch electrode blocks, the plurality of first-type touch electrode blocks comprising first touch electrode blocks and second touch electrode blocks; wherein the touch region at least partially surrounds the first component region; the touch region comprises a first touch region and a second touch region; the first touch region and the second touch region are respectively located at two sides of the first component region along a first direction; the first touch electrode blocks are located in the first touch region; the second touch electrode blocks are located in the second touch region; and first touch electrode groups arranged in the first region along a second direction, a number of the first touch electrode groups is m1, and one of the first touch electrode groups comprises at least two of the first touch electrode blocks arranged along the first direction and electrically connected to each other, m1 being a positive integer greater than or equal to 2;
m2 first connecting lines, wherein one of the m2 first connecting lines is electrically connected to both one first touch electrode group of the first touch electrode groups and one second touch electrode block of the second touch electrode blocks, m2 being an integer greater than or equal to 0, and m2<m1; and
wherein the first touch electrode groups comprise at least one first touch electrode group that is not electrically connected to the second touch electrodes through the first connecting lines.
