As shown in fig. 1, the display module 10a includes a vehicle-mounted touch panel 30 and a display panel 40, the vehicle-mounted touch panel 30 is disposed on a display surface 401 of the display panel 40, light emitted from the display panel 40 can pass through the touch panel 30, so that a user can conveniently view display information of the display panel 40, and the user can perform a corresponding touch operation according to display content of the display panel 40, so as to conveniently control a corresponding function of the automobile body 10. For example, corresponding touch operations can be performed on the touch panel 30 to control the operation of the ultraviolet disinfection apparatus 20.
As shown in fig. 2, in the present embodiment, the in-vehicle touch panel 30 includes a protective cover 1, a touch film 2, and an ultraviolet blocking layer 3. The protective cover 1 has a first surface 11 and a second surface 12 opposite to each other, and a side surface 13 connected to the first surface 11 and the second surface 12, respectively. The ultraviolet blocking layer 3 is arranged on the second surface 12, the touch control film 2 is arranged on the surface of the ultraviolet blocking layer 3 far away from the protective cover plate 1, and the display panel 40 is arranged on the surface of the touch control film 2 far away from the substrate. Specifically, in the present embodiment, the touch film 2 is adhered to the ultraviolet blocking layer 3 through the first optical adhesive layer 50, and the touch film 2 is adhered to the display surface 401 of the display panel 40 through the second optical adhesive layer 60.
In the present embodiment, the protective cover 1 is a transparent plate, such as a glass plate or the like. The uv blocking layer 3 may be formed on the second surface 12 of the protective cover 1 by a coating or plating process, wherein the material of the uv blocking layer 3 may be zinc oxide, titanium oxide, magnesium oxide, cerium oxide, aluminum oxide, polyvinylidene fluoride, or the like. Compared with the case where the ultraviolet blocking layer 3 is not provided, more than 90% of ultraviolet rays can be filtered after the ultraviolet blocking layer 3 is provided on the protective cover plate 1. Therefore, in the present embodiment, the ultraviolet blocking layer 3 is disposed to filter the ultraviolet rays emitted from the first surface 11 to the touch film 2, so as to protect the touch film 2, the display panel 40, and other elements. In this way, when the automobile body 10 is sterilized by the ultraviolet sterilizer 20, the touch film 2, the display panel 40, and the like are not damaged, and the service lives of the touch panel 30 and the display panel 40 are prolonged.

As shown in fig. 2, in the present embodiment, the vehicle-mounted touch panel 30 further includes an ink layer 4, the ink layer 4 is disposed between the ultraviolet blocking layer 3 and the edge region 22 to block the edge region 22, so that a user cannot see the trace of the edge region 22 on one side of the first surface 11, and the whole touch panel 30 is more beautiful. In this embodiment, the ink layer 4 extends to be flush with the side surface 13 of the substrate, so that light can be prevented from penetrating out of the edge of the substrate, and the shielding effect of the ink layer 4 is improved. In addition, in the present embodiment, the ink layer 4 is a ring structure, and the touch area 21 is opposite to the hollow portion of the ink layer 4.
As shown in fig. 2, in the present embodiment, the length and width of the protective cover 1 are generally larger than the length and width of the touch film 2, and after assembly, the periphery of the protective cover 1 protrudes out of the touch film 2, that is, a projection of the touch film 2 on the protective cover 1 has a certain distance from the side 13 of the protective cover 1.
As shown in fig. 3, in actual production, the automobile body 10 is usually provided with a corresponding mounting hole 101, and the touch panel 30 is fitted in the mounting hole 101. Wherein the mounting hole 101 may be a stepped hole, and a portion of the protective cover 1 protruding the touch film 2 abuts on a stepped surface 102 of the stepped hole. In order to increase the disinfection effect in this area, in which germs may also grow in the gap between the side 13 of the protective cover 1 and the side wall 103 of the mounting hole 101, the roughness of the side 13 is less than 1nm in this embodiment, which makes it easier for uv radiation to escape from the side 13 of the protective cover 1.
As shown in fig. 2 and 4, in the present embodiment, the touch film 2 includes a first touch electrode unit 23, a third optical adhesive layer 24, and a second touch electrode unit 25 sequentially stacked in a direction from the protective cover 1 to the touch film 2, wherein a touch capacitance is formed between the first touch electrode unit 23 and the second touch electrode unit 25 to detect touch information of a user.
