The connecting end 122 and the touch line 121 are disposed on the surface of the substrate 123 of the touch film 120, the connecting end 122 is electrically connected to the end of the touch line 121, and the connecting end 122 may be made of the same material as the touch line 121, for example, the connecting end 122 and the touch line 121 may be disposed on the surface of the substrate 123 of the touch film 120 by using a copper material, and the connecting end 122 and the touch line 121 are integrally disposed, thereby facilitating processing. The connection terminal 122 may also be made of a material different from that of the touch circuit 121, for example, the touch circuit 121 may be formed by a copper material on the surface of the substrate 123 of the touch film 120, and the connection terminal 122 may be formed by a conductive silver paste on the surface of the substrate 123 of the touch film 120, so that the connection terminal 122 has better conductivity, the contact impedance between the connection terminal 122 and the adapting portion 113 is reduced, and the conductive stability between the connection terminal 122 and the adapting portion 113 is improved.

In some embodiments, the interposer 113 may be made of anisotropic conductive adhesive, so that the interposer 113 can be directly adhered to the connecting terminal 122 and the conductive trace 132 through the interposer 113 while the interposer 113 is electrically connected to the connecting terminal 122 and the conductive trace 132. The interposer 113 may also be made of a metal material with good electrical conductivity, for example, the interposer 113 may be made of conductive silver paste, so as to reduce the connection impedance between the interposer 113 and the connection terminal 122 and the conductive trace 132.

To further ensure the stability of the electrical connection between the connection terminal 122 and the interposer 113, and between the conductive trace 132 and the interposer 113, as shown in fig. 4, in some embodiments, the light shielding region 112 is further provided with a conductive film 160, and the conductive film 160 can partially cover the surface of the interposer 113, so that the conductive film 160 is disposed corresponding to the connection terminal 122, the conductive trace 132 and the interposer 113, for example, the conductive film 160 can be divided into two parts, which are respectively disposed between the connection terminal 122 and the interposer 113, and between the conductive trace 132 and the interposer 113; alternatively, the conductive film 160 may cover the entire surface of the interposer 113.

For example, the conductive film 160 may be formed by ACF conductive adhesive, ACP conductive adhesive, or other adhesive, and disposed on the adapter 113 by printing or coating, and the thickness of the conductive film 160 may be correspondingly adjusted according to the distance between the adapter 113 and the connecting terminal 122, and the distance between the adapter 113 and the conductive trace 132, so as to further improve the connection stability.

Further, the edge of the conductive film 160 may extend to be connected to the light-shielding material in the light-shielding region 112 or the surface of the cover plate 110, so that the conductive circuit 132, the connecting terminal 122 and the conductive film 160 have a sufficient effective connection area, thereby improving the connection stability. Meanwhile, in the direction parallel to the surface of the cover plate 110, the adapter portion 113 and the connecting end 122, the adapter portion 113 and the end of the conductive trace 132 may be disposed in a staggered manner, so that the coverage area of the conductive trace 160 is enlarged, and the adapter portion 113, the connecting end 122 and the conductive trace 132 can be electrically conducted even when the three are connected in a staggered manner, thereby making the installation more flexible. In addition, the conductive film 160 is disposed between the transfer terminal and the transfer portion 113 or between the transfer portion 113 and the conductive trace 132, so as to prevent external impurities from being introduced between the connection structures of the transfer portion 113 and the transfer terminal, and the connection structures of the transfer portion 113 and the conductive trace 132, thereby improving the stability of the electrical conduction. When the edge position of the conductive film 160 is adjusted, there should be a gap between the conductive films 160 disposed on two adjacent adapters 113 to avoid short circuit between two adjacent adapters 113.

The conductive film 160 can be connected to the surface of the substrate 123 of the touch film 120 and the surface of the circuit board main body 131 of the adapting circuit board 130 while connecting the adapting portion 113, the connecting end 122 and the conductive trace 132, the edge of the conductive film 160 extends to be connected to the light-shielding material in the light-shielding region 112 or the surface of the cover plate 110, and the conductive film 160 can also support the substrate 123 and the circuit board main body 131 by adjusting the thickness of the conductive film 160 along the direction perpendicular to the plate surface of the cover plate 110, thereby improving the stability of connection between the touch film 120 and the adapting circuit board 130.
