Through the research of the inventor of the present invention, as shown in fig. 1 and fig. 2, after the foldable touch module in the related art is folded inwards, the cover plate 2 is located at the inner side of the foldable display device, so that the cover plate 2 bears a large compressive stress, and wrinkles are easily generated under the influence of the compressive stress. In order to solve the problem that the cover plate 2 is wrinkled, the cover plate 2 in the foldable display device in the related art adopts a retraction design relative to the touch panel 1, so that the cover plate 2 cannot completely cover the touch panel 1, the touch leads 3 in part of the touch panel 1 are exposed, the antistatic capability of the foldable touch module is greatly reduced, and the problem that the touch leads 3 are damaged by electrostatic shock can occur.

In an exemplary embodiment, the structure of the non-bending region 110 positioned at both sides of the bending region 100 may be the same to form a display device having a symmetrical structure. In some embodiments, the non-bending regions 110 on both sides of the bending region 100 can be made into different structures according to the requirement.
Fig. 4 is a cross-sectional view of a foldable touch module according to an embodiment of the invention. Take fig. 4 as an example of a cross-sectional view in the direction of B-B' in fig. 3. As shown in fig. 3 and 4, the foldable touch module according to the embodiment of the invention includes a touch panel 1 and a cover plate 2 stacked in a direction perpendicular to the foldable touch module. The touch panel 1 and the cover plate 2 are both foldable structures, and can be folded and unfolded to realize the folding and flattening of the foldable display device.
In an exemplary embodiment, the bending state of the foldable touch module according to the embodiment of the invention includes a folded-in state. The inward-folding state refers to that the cover plate 2 is located at the innermost side of the foldable touch module after the foldable touch module is bent, so that the touch panel 1 can be effectively protected from external impact in the bending state, and the risk of failure of the touch panel 1 is reduced. According to the embodiment of the invention, the cover plate 2 in the foldable touch module does not completely cover the touch panel 1, and the cover plate 2 can be prevented from generating wrinkles after the foldable touch module is folded inwards.
In an exemplary embodiment, as shown in fig. 3 and 4, the touch panel 1 includes a non-exposed region 101 and an exposed region 102, the exposed region 102 is located on at least one side of the non-exposed region 101, a vertical projection of the cover plate 2 on the touch panel 1 overlaps the non-exposed region 101, and a vertical projection of the cover plate 2 on the touch panel 1 does not overlap the exposed region 102. Specifically, the touch panel 1 and the cover plate 2 are both rectangular, the exposed region 102 is located on one side of the non-exposed region 101, and the exposed region 102 is not formed on the other three sides of the touch panel 1, i.e., the other three sides of the touch panel 1 are flush with the corresponding three sides of the cover plate 2.
In an exemplary embodiment, as shown in fig. 4, the non-exposed region 101 includes a touch electrode layer 1011 and a second insulating layer 1012 disposed between the touch electrode layer 1011 and the cover plate 2.

The touch lead 3 in the exposed region 102 is connected to the touch electrode layer 1011 in the non-exposed region 101 for transmitting a touch signal. The touch lead 3 may be a driving lead (Tx) or a sensing lead (Rx). The substrate 1021 may be made of PET (polyethylene terephthalate) material or COP material. The fourth insulating layer 1022 may be disposed on the same layer as the second insulating layer 1012 of the non-exposed region 101, and may be formed by the same manufacturing process using the same material.
In an exemplary embodiment, a vertical projection of the electrostatic shielding layer 4 on the substrate 1021 at least partially overlaps a vertical projection of the at least one touch lead 3 on the substrate 1021. The electrostatic shielding layer 4 can shield external static electricity, so that the antistatic performance of the foldable touch module is improved, and the problem that the touch lead 3 is damaged by static electricity is solved. In addition, the electrostatic shielding layer 4 can protect the touch lead 3, and the water and oxygen corrosion resistance of the foldable touch module is improved.
In an exemplary embodiment, the electrostatic shielding layer 4 includes at least one shielding layer having a function of shielding static electricity. The vertical projection of the at least one shielding layer on the substrate 1021 and the vertical projection of the at least one touch lead 3 on the substrate 1021 are at least partially overlapped, so as to prevent the touch lead 3 from being damaged by electrostatic shock. The shielding layer may be made of a metal material.
In an exemplary embodiment, the electrostatic shielding layer 4 in the foldable touch module according to an embodiment of the invention may include multiple shielding layers, for example, the electrostatic shielding layer 4 may include two, three, or four shielding layers, as long as a vertical projection of at least one shielding layer on the substrate 1021 and a vertical projection of at least one touch lead 3 on the substrate 1021 at least partially overlap. The multi-layer shielding layer can shield external noise and electromagnetic waves in a multi-stage mode, static electricity is absorbed, and therefore the antistatic capacity of the foldable touch module is greatly improved. Meanwhile, the touch lead 3 of the exposed area 102 can be protected from being corroded by water oxygen, and the reliability of the foldable touch module is improved.

The thicknesses of the first shielding layer 401a and the second shielding layer 401b can be 0.1-0.2 μm, so that the first shielding layer 401a and the second shielding layer 401b can better shield static electricity, and the thickness of the electrostatic shielding layer 4 is not too thick. The first insulating layer 402 may be prepared by photolithography or a coating process. The thickness of the first insulating layer 402 may be 3 to 5 μm, and the first insulating layer 402 can insulate between the first shielding layer 401a and the second shielding layer 401b without causing an excessive thickness of the electrostatic shielding layer 4.
