The present utility model is described in detail below with reference to the drawings and the embodiments, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

Example 1

Referring to fig. 1 and 2, an OGS touch screen provided by the present utility model includes a touch glass 1, a first protection film 2, a BM layer 3, a second protection film 4 and a third protection film 5, where the first protection film 2 is disposed on an upper surface of the touch glass 1, the BM layer 3 is disposed on a lower surface of the touch glass 1, a binding region and an unbinding region are disposed below the touch glass 1, the second protection film 4 is disposed on the lower surface of the BM layer 3, the second protection film 4 is located in the unbinding region, the third protection film 5 is also disposed on the lower surface of the BM layer 3, but the third protection film 5 is located in the binding region. Because the lower surface of the touch glass 1 is provided with two protective films, the two protective films are respectively a second protective film 4 arranged in an unbound region and a third protective film 5 arranged in a bound region, when the binding region works, only the third protective film 5 positioned in the bound region is required to be torn off, the second protective film 4 positioned in the unbound region is still reserved, and a layer of process protective film is not required to be re-adhered in the unbound region after the production process is finished; the second protective film 4 is directly torn off when the OGS touch screen is transported to an assembly factory to be assembled with the display screen, so that the second protective film 4 and the third protective film 5 are consumed in the whole process, the areas of the two protective films are equal to the area of a blue film in the traditional technology, one process protective film is saved, the film pasting and film tearing flow of the process protective film are also saved, the process flow is reduced while the material waste is avoided, the process flow is not required to be changed on the basis of the existing process flow, the assembly post is not required to be additionally arranged, the defective products are effectively reduced, the production and manufacturing cost of the OGS touch screen are greatly reduced, the product competitiveness of the OGS touch screen is improved, and the increasing quality requirements of enterprises are met.

Further, the distance between the second protective film 4 and the third protective film 5 was 0.5mm.

Further, the thickness of the touch glass 1 was 7mm, the thickness of the bm layer 3 was 0.06mm, and the thicknesses of the first protective film 2, the second protective film 4, and the third protective film 5 were all 0.03mm.

Further, the first protective film 2, the second protective film 4, and the third protective film 5 are all blue films.

Example 2

Referring to fig. 3 and fig. 4, in this embodiment, as a further optimization scheme of embodiment 1, a "concave" through hole 6 is provided on the third protection film 5, and the "concave" through hole 6 forms a film tearing handle, and the film tearing handle is not required to be added on the periphery of the third protection film 5, so that the film tearing handle cannot be placed due to limitation of peripheral space, and the situation that tweezers are required to be used for warping during limitation of the peripheral space is avoided, thereby saving labor cost; and the peripheral film tearing handle material can be omitted, so that the material cost can be greatly reduced.

Referring to fig. 5, further, the waste 7 of the "concave" shaped through hole 6 remains on the third protective film 5. The scrap 7 remains attached to the third protective film 5 before the third protective film 5 is torn off, and dust or other particulate matter is effectively prevented from entering the surface of the product. Because the waste 7 is still connected to the third protection film 5, it is difficult to tear the film tearing handle, so that an adhesive area 8, preferably adhesive, can be arranged on the upper surface of the waste 7, but the waste 7 can be torn off by means of adhesive when the third protection film 5 is torn off, and the third protection film 5 is torn off by the film tearing handle.

Further, the concave-shaped through hole 6 is formed in the edge of the third protective film 5, so that the third protective film 5 is easy to tear when being torn, and the tearing of the film tearing handle due to high tearing difficulty is avoided.

Further, each corner of the concave through hole 6 is provided with a rounded corner 9, so that stress during film tearing is not concentrated at the corner, the film tearing handle is prevented from being torn due to stress concentration, and the operation efficiency is further improved.

Further, the radius of the rounded corners 9 is 1mm.

Example 3

Referring to fig. 6, in this embodiment, as a further optimization scheme of embodiment 1, the second protective film 4 and the third protective film 5 are combined into one integral protective film, and a tearing line 10 is provided on a boundary line between the non-binding area and the binding area of the integral protective film, so that when a worker needs to tear off the protective film of the binding area, the integral protective film at the binding area can be directly torn off through the tearing line 10, and the integral protective film at the non-binding area is reserved, so that only one integral protective film needs to be attached when the protective film is attached, and two protective films do not need to be attached, thereby further reducing the process flow and improving the working efficiency.

In the present utility model, unless explicitly specified and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise.
