The touch units 2 and the connecting lines 3 are connected in a one-to-one correspondence, and are located on the substrate 1. The touch unit 2 is located in the touch area 4, and the connection line 3 is located in the wiring area 5. At least two connecting lines 3 are distributed in each wiring area 5, that is, two or more connecting lines 3 can be distributed in each wiring area 5, and the specific situation is determined according to the actual situation.

In the touch-control display substrate of this embodiment, at least two connecting wires 3 distribute in every wiring district 5, under the unchangeable prerequisite of the quantity of connecting wire 3, the area that connecting wire 3 occupied in the touch-control display substrate of this embodiment is far less than the area that connecting wire 3 occupied of the touch-control display substrate of prior art (only distribute a connecting wire 3 in every wiring district 5), the proportion of 2 areas of touch-control unit of the touch-control display substrate of this embodiment will increase relatively speaking, thereby increase touch-control area (be equivalent to reduce the blind area, if reduce 50% blind area), and then promote touch-control linearity, performances such as touch-control precision.

Specifically, the distribution of the touch unit 2 and the connecting lines 3 is shown in fig. 2. By "the connecting lines 3 corresponding to the touch units 2 close to the first direction are farther from the row of touch units 2 than the connecting lines 3 corresponding to the touch units 2 far from the first direction", the connecting lines 3 are not overlapped mutually, so as to ensure that the connecting lines 3 are not short-circuited.
It should be noted that there may be one wiring area 5 between two adjacent columns of touch units 2, or there may be multiple wiring areas 5.
The touch units 2 and the connecting lines 3 are distributed neatly, and the area of the layout of the connecting lines 3 is saved, so that the difficulty of the manufacturing process of the touch display substrate is reduced, and the touch linearity and the touch precision performance are improved.
