Description

Technical Field

[0001] The utility model relates to the technical field of touch screen protective films, in particular to a touch screen structure convenient for semi-permeable hole testing. Background Art

[0002] At present, during the installation process of the touch screen, it is necessary to first tear off the release film on the foam. If the release film is colorless and transparent, it is very difficult for workers or machines to identify the position of the release film tearing handle, and it is easy to cause the situation of missed tearing. Therefore, it is necessary to replace the foam release film with a colored one (such as blue). However, the colored release film will affect the test effect when testing the IR holes of the test cover plate, and it is necessary to tear off the colored release film to conduct the test. At this time, it will also cause waste of the touch screen. The more tests are conducted, the more waste will be caused. Summary of the Utility Model

The positions of the two IR openings 17 correspond to those of the two IR holes 11, and the diameter of the IR opening 17 is the same as that of the IR hole 11. It should be noted that this design enables the touch screen cover plate 1 not to tear off the release film 16 and the transparent protective film 13 during the IR hole measurement process.

[0030] As Figures 1 - 3 shown in one embodiment, the shape and size of the front side of the transparent protective film 13 are the same as those of the top part of the front side of the touch screen cover plate 1. It should be noted that this design enables the transparent protective film 13 to protect the top part of the touch screen cover plate 1 without affecting its bottom display area.

[0031] As Figures 1 - 3 shown in one embodiment, a protective film peeling handle is provided on the left side of the top of the front side of the transparent protective film 13, and an auxiliary peeling handle 15 is attached to the left side of the protective film peeling handle.

[0032] As Figures 1 - 3As shown, in one embodiment, an adhesive layer is provided on one side of the auxiliary peeling handle 15 close to the transparent protective film 13, and the peeling handle of the transparent protective film 13 is adhered together through this adhesive layer. A peeling handle for the release film is provided on the left side of the top of the front surface of the release film 16. The shape and size of the front surface of the peeling handle of the release film 16 are the same as those of the front surface of the peeling handle of the transparent protective film 13. It should be noted that since the shapes and sizes of the peeling handles of the transparent protective film 13 and the release film 16 are the same, the auxiliary peeling handle 15 can be conveniently distinguished and peeled during installation.

[0033] As Figures 1 - 3 shown, in one embodiment, the four corners of the front surface of the touch screen cover plate 1 are rounded.

[0034] The above-described embodiments merely represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
