1. A touch display panel, comprising:
a substrate;
a display region disposed on the substrate;
a first touch electrode disposed in the display region;
a second touch electrode disposed in the display region; and
a third touch electrode disposed in the display region, the first touch electrode, the second touch electrode and the third touch electrode arranged adjacently, and the third touch electrode and the second touch electrode electrically disconnected;
the second touch electrode is electrically connected to the first touch electrode, and an area of the third touch electrode is greater than an area of the first touch electrode and/or an area of the second touch electrode; wherein,
the first touch electrode has a first area S1, and the second touch electrode has a second area S2, where Smin≤(S1+S2)≤Smax, Smin is the minimum design area of each of the touch electrodes, and Smax is the maximum design area of each of touch electrodes.
