[0022] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0023] This application proposes a scratch-resistant touch screen, please refer to Figure 1 and Figure 2, including a screen body 10, a first protective film 20 and a second protective film 30. The screen body 10 includes a display area and a semi-transparent hole area. The bonding surfaces of the first protective film 20 and the second protective film 30 are sticky. The first protective film 20 is attached to the surface of the semi-transparent hole area, and the second protective film 30 is attached to the surface of the display area. The edge of the first protective film 20 is bonded to the edge of the second protective film 30, and then the first protective film 20 and the second protective film 30 are spliced. When the touch screen is attached to the backlight, the staff will tear off the second protective film 30 on the display area, leaving the first protective film 20 to protect the semi-transparent area. After attaching the backlight, it can be shipped directly to customers without attaching a protective film to the semi-transparent area again, saving processes and protective films and reducing costs.

[0024] Preferably, when tearing off the second protective film 30, the staff or automated equipment presses down the first protective film 20 while tearing off the second protective film 30. When the display area is completely torn off the second protective film 30, the staff or automated equipment releases the first protective film 20. The viscosity of the first protective film 20 is stronger than that of the second protective film 30, which makes it easier for the staff to tear off the second protective film 30, so that the first protective film 20 will not tend to be torn off along with the second protective film 30, leaving the first protective film 20 in the semi-permeable hole area, reducing the work intensity of the staff. Specifically, the material model of the first protective film 20 is TS628, and the material model of the second protective film 30 is CG619TAS.

[0025] In one embodiment, see Figure 1, a dotted separation line 21 is provided on the first protective film 20, and the staff only needs to press the first protective film 20 side of the separation line 21, and then tear off the second protective film 30, so that the sticky substance of the second protective film 30 left on the first protective film 20 is separated together with the second protective film 30. Furthermore, when the staff tears off the second protective film 30, there is no place to start, and then a tearing handle 31 is provided on the second protective film 30. The staff only needs to pull the tearing handle 31 to tear off the second protective film 30, thereby improving work efficiency. Specifically, the tearing handle 31 is provided at the edge of the second protective film 30, which further facilitates the staff to tear off the second protective film 30. However, if the tearing handle 31 is connected to the two sides or the lower area of ​​the second protective film 30, the touch screen will occupy a larger space, and a larger blister needs to be designed to place the touch screen. In the present application, the tearing handle 31 is bent and attached to the surface of the second protective film 30, so that the area of ​​the blister tray is reduced, the transportation space is reduced, and the packaging cost is reduced. Furthermore, the scratch-resistant touch screen also includes a non-sticky isolation film 40, the semi-permeable hole area is provided with an optical hole, the isolation film 40 is arranged in the optical hole, and the height of the isolation film 40 is greater than the depth of the optical hole, so that the first protective film 20 abuts against the semi-permeable hole area through the isolation film 40, preventing the ink layer on the semi-permeable hole area from chemically reacting with the sticky substance on the first protective film 20 to damage the touch screen, thereby affecting the display effect of the touch screen.

[0026] In another embodiment, see Figure 2 The screen body 10 includes a cover plate 11 and a touch screen 12. The cover plate 11 is provided with an opening, and the touch screen 12 is embedded in the opening. The semi-permeable area is provided on the cover plate 11, and the display area is provided on the touch screen 12. The cover plate 11 is used to protect the touch screen 12, and the touch screen 12 is used to display the picture. In addition, the cover plate 11 is a rectangular parallelepiped structure, and the four sides of the cover plate 11 are provided with chamfers 50. The setting of the chamfers 50 increases the contact area. When a person hits the four sides of the cover plate 11, the pressure increases, which can prevent injury or reduce the degree of injury.

[0027] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
