    Abstract: A touch display panel is disclosed. The touch display panel includes first touch electrodes and second touch sub-electrodes. The first touch electrodes are insulated from and intersect with the second touch sub-electrodes. At least two of the first touch electrodes are connected as at least one first touch electrode group, where each first touch electrode group is connected with a touch drive detection unit through a wire. In addition, second touch sub-electrodes corresponding to each of the first touch electrode groups form a second touch electrode group. Each second touch electrode group includes second touch electrode units, each including at least two second touch sub-electrodes. Each of the second touch sub-electrodes is connected with the touch drive detection unit through a different wire. Additionally, the touch drive detection unit transmits a touch drive signal to or receives a detection signal from the first touch electrodes or the second touch sub-electrodes.
