As shown in fig. 1, in an embodiment, the touch display module 10 includes a cover plate 100, a substrate 200, and a touch module 300 disposed on a side of the cover plate 100 adjacent to the substrate 200. In the present embodiment, the cover plate 100 is disposed opposite to the base plate 200. The touch module 300, i.e. the touch sensing module, is located between the cover plate 100 and the substrate 200, and the touch module 300 is disposed inside the cover plate 100, i.e. the touch module 300 is formed on one side of the cover plate 100 adjacent to the substrate 200. In one embodiment, the substrate 200 is provided with a display module. In this embodiment, a cathode layer is disposed on the display module.

In one embodiment, the electrode layer 310 is disposed on the cover plate 100. In this embodiment, the electrode layer is formed on the cover plate. Referring to fig. 3, in one embodiment, the electrode layer 310 is provided with a touch pattern area 311 and an external trace 313 that are electrically connected. In one embodiment, the outer trace 313 is disposed around the touch pattern area 311, so that the layout of the outer trace 313 of the electrode layer 310 is more compact and reasonable. In an embodiment, the touch pattern area 311 is a layer structure, i.e. the touch pattern area is a touch pattern layer, so that the structure of the touch pattern area 311 is simple. In the present embodiment, the touch pattern area 311 is a bump layer structure, i.e. the thickness of the touch pattern area is thicker than that of the external wiring. In other embodiments, the touch pattern area 311 may also be a concave layer structure, i.e. the thickness of the touch pattern area is thinner relative to the thickness of the external wires.
As shown in fig. 2 and 3, in one embodiment, the insulating layer 320 is disposed on the electrode layer 310, i.e., the insulating layer is formed on the electrode layer.

As shown in fig. 2, in one embodiment, the shielding layer 330 is located on a side of the insulating layer 320 facing away from the electrode layer 310. The shielding layer 330 corresponds to the touch pattern region 311. The auxiliary electrode layer 340 is located on the side of the insulating layer 320 facing away from the electrode layer 310. The auxiliary electrode layer 340 and the shielding layer 330 are disposed on the same layer of the touch module 300, and the auxiliary electrode layer 340 is located at the periphery of the shielding layer 330. In this embodiment, the auxiliary electrode layer 340 and the shielding layer 330 are formed on the same layer of the touch module 300. The external trace 313 is electrically connected to the auxiliary electrode layer 340 through the via 322. In one embodiment, the shielding layer 330 is grounded through the auxiliary electrode layer 340, so that a coupling capacitance generated between the electrode layer 310 and the cathode layer of the display module is partially grounded through the shielding layer 330, thereby enabling the shielding layer 330 to have a better shielding effect and greatly reducing the interference between the touch module 300 and the display module.
The touch display module and the touch display screen described above, the touch module 300 is disposed on one side of the cover plate 100 adjacent to the substrate 200, i.e. formed on the inner side of the cover plate 100. The insulating layer 320 is located between the electrode layer 310 and the auxiliary electrode layer 340, so that the electrode layer 310 and the auxiliary electrode layer 340 are respectively located at two sides of the insulating layer 320, and the external trace 313 of the electrode layer 310 is electrically connected with the auxiliary electrode layer 340 through the via hole 322, so that the touch signal generated by the touch pattern area 311 is sequentially conducted to the control chip of the substrate 200 through the external trace 313 and the touch electrode layer 310, thereby realizing the touch function of the touch display module. In this embodiment, the positions of the outer wires corresponding to the vias are provided with bonding contacts, and the bonding contacts are located in the vias and are in contact electrical connection with the auxiliary electrode layer, so that the outer wires 313 of the electrode layer 310 are electrically connected with the auxiliary electrode layer 340 through the vias 322, and thus the paths for electrically connecting the electrode layer with the auxiliary electrode layer are shortest, and meanwhile, the outer wires can be better fixedly mounted on the cover plate.

Because the shielding layer 330 corresponds to the touch pattern area 311, and the auxiliary electrode layer 340 is located at the periphery of the shielding layer 330, the electrode layer 310 is separated from the display module on the substrate 200 by the shielding layer 330, the coupling capacitance generated by the electrode layer 310 and the cathode layer of the display module is conducted to the shielding layer 330, and the shielding layer 330 is grounded through the auxiliary electrode layer 340, so that the coupling capacitance is greatly reduced, the interference between the touch module 300 and the display module is reduced, and the problem of larger interference between the touch module 300 and the display module is solved. Because the shielding layer 330 and the auxiliary electrode layer 340 are disposed on the same layer of the touch module 300, that is, the shielding layer 330 is manufactured by using a partial region of the auxiliary electrode layer 340, the quality of the touch display module is improved on the premise of unchanged cost. A shielding layer 330 is formed between the touch module 300 and the display module, so that the coupling capacitance between the touch module 300 and the display module is reduced, and the interference is reduced.

In an embodiment, the touch pattern area 311 (i.e. the AA area) is divided into N self-contained squares, and specific division can be set according to the requirements of different touch display chips to satisfy different touch functions, so that the touch pattern area 311 has better applicability.

It is understood that in other embodiments, the area of the touch pattern region 311 may be larger than the area of the shielding layer 330. Or the area of the touch pattern region 311 may be smaller than that of the shielding layer 330, so that the shielding layer 330 has a better shielding effect.
