Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be arbitrarily combined with each other.
FIG. 1 is a top view of a foldable touch module; fig. 2 is a cross-sectional view of a foldable touch module. Take fig. 2 as an example, which is a sectional view taken along the direction A-A' in fig. 1. As shown in fig. 1 and fig. 2, the present inventors have found that, after the foldable touch module in the related art is folded, the cover 2 is located at the inner side of the foldable display device, so that the cover 2 is subjected to a larger 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 generates wrinkles, the cover plate 2 in the foldable display device in the related art adopts a shrinking 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 static electricity can occur.

In an exemplary embodiment, as shown in fig. 3, in a direction parallel to the foldable touch module, the foldable touch module of the embodiment of the invention includes a bending region 100 and non-bending regions 110 respectively located at two sides of the bending region 100. The non-bending region 110 can rotate around the bending region 100 to fold and flatten the foldable touch module.
In an exemplary embodiment, the structures of the non-inflection regions 110 located at both sides of the inflection region 100 may be identical to form one display device with structural symmetry. In some embodiments, the non-inflection regions 110 on either side of the inflection region 100 may be configured differently as desired.
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, which is a sectional view taken along the direction B-B' in fig. 3. As shown in fig. 3 and 4, in a direction perpendicular to the foldable touch module, the foldable touch module according to the embodiment of the invention includes a touch panel 1 and a cover 2 that are stacked. The touch panel 1 and the cover plate 2 are of foldable structures, and folding and flattening of the foldable display device can be achieved.
In an exemplary embodiment, the bending state of the foldable touch module includes an inward bending state. The inward folding state refers to that after the foldable touch module is folded, the cover plate 2 is located at the innermost side of the foldable touch module, so that the touch panel 1 can be effectively protected from external impact in the folding state, and the risk of failure of the touch panel 1 is reduced. In the foldable touch module of the embodiment of the invention, the cover plate 2 does not completely cover the touch panel 1, and after the foldable touch module is folded inwards, the cover plate 2 can be prevented from generating wrinkles.
In an exemplary embodiment, as shown in fig. 3 and 4, the touch panel 1 includes a non-exposed area 101 and an exposed area 102, the exposed area 102 is located on at least one side of the non-exposed area 101, a vertical projection of the cover plate 2 on the touch panel 1 overlaps the non-exposed area 101, and a vertical projection of the cover plate 2 on the touch panel 1 does not overlap the exposed area 102. Specifically, the touch panel 1 and the cover 2 are both rectangular, the exposed area 102 is located at one side of the non-exposed area 101, and the other three sides of the touch panel 1 are not formed with the exposed area 102, i.e. the other three sides of the touch panel 1 are flush with the corresponding three sides of the cover 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 an sensing lead (Rx). The material of the substrate 1021 may be 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 formed by the same manufacturing process using the same material.
In an exemplary embodiment, the perpendicular projection of the electrostatic shielding layer 4 on the substrate 1021 at least partially overlaps with the perpendicular 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. And, electrostatic shielding layer 4 can protect touch lead 3, promotes the anti-oxidation of water oxygen of collapsible touch module and corrodes the performance.
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 at least one shielding layer on the substrate 1021 and the vertical projection of at least one touch lead 3 on the substrate 1021 are at least partially overlapped, so that the touch lead 3 is prevented from being damaged by static electricity. Wherein, the shielding layer can be made of metal materials.
In an exemplary embodiment, the electrostatic shielding layer 4 in the foldable touch module of the embodiment of the present invention may include a plurality of shielding layers, for example, the electrostatic shielding layer 4 may include two, three, or four shielding layers, so long as the vertical projection of at least one shielding layer on the substrate 1021 at least partially overlaps the vertical projection of at least one touch lead 3 on the substrate 1021. The multi-layer shielding layer can carry out multi-stage shielding on external noise and electromagnetic waves and absorb static electricity, so that 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 and oxygen, so that the reliability of the foldable touch module is improved.

At least one of the first shielding layer 401a and the second shielding layer 401b at least partially overlaps with the vertical projection of the at least one touch lead 3 on the substrate 1021, so as to improve the antistatic performance and the anti-oxygen corrosion performance of the foldable touch module. Wherein, the first shielding layer 401a and the second shielding layer 401b may be prepared by photolithography or electrodeposition process.

The first insulating layer 402 may be prepared by a photolithography or coating process. The thickness of the first insulating layer 402 may be 3-5 μm, and the first insulating layer 402 can insulate between the first shielding layer 401a and the second shielding layer 401b without causing the thickness of the electrostatic shielding layer 4 to be excessively thick.

For example, the material of the touch electrode layer 1011 is a metal material, and at least one of the material of the first shielding layer 401a and the material of the second shielding layer 401b is a metal material.
