In this way, the light incoming degree of the touch screen 10 can be ensured, so that the touch screen 10 with the protection structure 100 also has the characteristic of good light transmission.

It is worth mentioning that the manufacturing process of the touch screen 10 with the protection structure 100 requires a visual inspection, for example: and tearing the outer film to perform appearance inspection or scanning the two-dimensional code through the double-layer film structure. And (3) tearing the outer film to carry out appearance inspection, namely tearing off the first outer film layer structure 24, and inspecting the optical transmittance and the haze of the first inner film layer structure 23. Scanning the two-dimensional code through the double-layer film structure is to scan the two-dimensional code through the first film structure 20, and the haze of the first film structure 20 is used for inspection.

In particular, optical transmittance refers to the percentage of luminous flux of light transmitted through a transparent or translucent body to the luminous flux of light incident thereon. Haze refers to the appearance of a haze or cloudiness of light transmitted through the interior or surface of a transparent or translucent material due to light diffusion, expressed as a percentage of the ratio of the amount of light diffused to the amount of light transmitted through the material.

In one embodiment, when the protective structure 100 with the touch screen 10 is a two-layer protective structure (as shown in FIG. 6), the protective structure 100 includes a first inner film layer structure 23.

Therefore, the light incoming degree of the touch screen 10 can be ensured, so that the touch screen 10 with the protection structure 100 also has the characteristic of light transmission.

It should be noted that, when the protective structure 100 with the touch screen 10 is a double-layer protective structure (as shown in fig. 6), the protective structure 100 with the touch screen 10 may also be subjected to appearance inspection through the first film structure 20, and the haze of the first film structure 20 should be less than or equal to 20%.

The protective structure 100 with the touch screen 10 may be visually inspected through the second inner film layer structure 24. The optical transmittance of the second inner film layer structure 24 should be greater than or equal to 88% and the haze should be less than or equal to 2%. Therefore, the light incoming degree of the touch screen 10 can be ensured, so that the touch screen 10 with the protective structure 100 also has the characteristic of light transmission.

In another example, when the protective structure 100 with the touch screen 10 is a single-layer protective structure (as shown in fig. 5), the protective structure 100 includes the second film-layer structure 30, and the protective structure 100 with the touch screen 10 can be subjected to appearance inspection through the second film-layer structure 30, the haze of the second film-layer structure 30 should be 20% or less. Therefore, the light incoming degree of the touch screen 10 can be ensured, so that the touch screen 10 with the protection structure 100 also has the characteristic of light transmission.

It should be noted that, when the protective structure 100 with the touch screen 10 is a double-layer protective structure (as shown in fig. 6), the protective structure 100 with the touch screen 10 may also be subjected to appearance inspection through the second film structure 30, and the haze of the second film structure 30 should be less than or equal to 20%.

In some embodiments, the touch screen 10 with the protective structure 100 can be directly applied to the embodiment shown in fig. 1 without performing a visual inspection after the manufacturing process.

In certain embodiments, the contact structure 40 is one or a combination of two or a combination of three of the following: ink dot layer, matte layer, dull polish layer.

As such, the contact structure 40 has various embodiments, and the corresponding contact structure 40 may be selected according to the film layer structure of different materials.

Specifically, when the contact structures 40 formed by the ink dot layers are stacked together with the protective structure 100 of the touch screen 10, the protruding structures of the ink dots can reduce the contact area between the film structures, thereby reducing the adsorption force between the film structures and avoiding lamination. Both the matte layer formed contact structure 40 and the matte layer formed contact structure 40 may form an uneven surface to reduce the contact area between the film structures when the protective structure 100 with the touch screen 10 is stacked together, thereby reducing the adsorption force between the film structures and avoiding lamination. In certain embodiments, the contact structure 40 may be at least one of an ink dot layer, a matte layer, a frosted layer. Thus, the contact structure 40 has various embodiments, and the corresponding contact structure 40 is selected according to the film layer structure of different materials. For example: the first outer surface 221 is provided with a contact structure 40 formed by an ink dot layer, and the second outer surface 322 is provided with a contact structure 40 formed by a matte layer (as shown in fig. 7); both the first outer surface 221 and the second outer surface 322 are provided with a frosted layer (as shown in fig. 8).

In some embodiments, the ink dot layer includes a plurality of ink dots, and the ink dots can have a thickness of 8um to 11um, such as 8um, 9um, or 11um, among others. The thickness of the matte layer may be 5um to 8um, such as 5um, 6um, or 8um, etc. The thickness of the sanding layer may be 5um-8um, such as 5um, 6um, or 8um, etc.

Therefore, the thickness of the protection structure 100 is not increased while the adsorption force between the film layer structures is reduced, and the influence on the good light transmission of the protection structure 100 is avoided. It should be noted that the above examples and specific numerical values are for convenience of describing the implementation of the present invention, and should not be construed as limiting the scope of the present invention.

Referring to fig. 1, 5 and 6, the present invention discloses a touch screen assembly 1000, which includes a touch screen 10 and a protection structure 100 according to any of the above embodiments. The touch screen 10 includes opposing first and second surfaces 12, 14, with the first film layer structure 20 of the protective structure 100 covering the first surface 12 via a first attachment face 211. The second film layer structure 30 covers the second surface 40 via the second connection surface 311.

The utility model discloses embodiment's touch-sensitive screen subassembly 100 includes touch-sensitive screen protection architecture 100, and first surface 221 is equipped with the contact structure 40 that can reduce area of contact with second surface 322, and when a plurality of touch-sensitive screen subassemblies 1000 are stacked together like this, through the contact structure 40 contact, therefore reducible area of contact has reduced the adsorption affinity between the membranous layer structure, avoids the lamination, has satisfied automated production's demand.
