Description

Technical Field

[0001] The utility model relates to the field of touch screens, in particular to a touch screen cover integrated film structure. Background Technique

[0002] The IR hole, also known as the infrared hole, is located at a specific position of the touch screen device and is mainly used for the infrared penetration of the light sensor and the distance sensor, and can realize functions such as automatically adjusting the screen brightness and detecting the distance of an object. Therefore, it is particularly necessary to detect the transmittance of the IR hole to ensure that the IR hole can work normally.

[0003] Before installing the touch screen, if it is necessary to detect the IR hole, it is usually necessary to tear off the release film on the adhesive layer. If the release film is colorless and transparent, it is difficult for manual or machine to judge the position of the release film tearing handle, and it is easy to cause the situation of missed tearing. Therefore, the release film on the adhesive layer needs to be set to be colored. However, the colored release film will affect the test effect of the cover IR hole. At this time, it is necessary to tear off the colored release film before testing, and tearing off the release film will damage the adhesive layer. The more times of testing, the greater the damage degree to the adhesive layer. Content of the Utility Model

[0023] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings

[0024] Please refer to Figures 1 to 3 , a touch screen cover plate integrated film structure, comprising: a cover plate 10, the cover plate 10 includes a visible area 100 and a non-visible area 200, an adhesive layer 210, a release film 220 and a protective film 230 are sequentially arranged on the non-visible area 200, a plurality of IR holes 240 are further arranged on the non-visible area 200, a plurality of hollowed-out areas 250 are arranged on both the adhesive layer 210 and the release film 220, the IR holes 240 and the hollowed-out areas 250 are in one-to-one correspondence, a first handle part 221 is arranged on the release film 220, a second handle part 231 is arranged on the protective film 230, the first handle part 221 and the second handle part 231 are arranged opposite to each other, and an identification coating 232 is arranged on one side of the second handle part 231 close to the first handle part 221

[0025] It should be noted that the adhesive layer 210, the release film 220 and the protective film 230 are set as an integrated film, so that the user does not need to perform multiple assemblies when installing the integrated film. When the transmittance of the IR holes 240 in the non-visible area 200 needs to be tested, it can be done manually or by machine. The protective film 230 is torn off through the second handle part 231 with the identification coating 232. The IR holes 240 and the hollowed-out areas 250 are in one-to-one correspondence, so that when the transmittance of the IR holes 240 is tested, the release film 220 does not need to be torn off and is not interfered by the release film 220, avoiding damage to the adhesive layer 210 caused by tearing off the release film 220. After the transmittance test of the IR holes 240 is completed, the protective film 230 can be covered back in place to avoid soiling of the IR holes 240. When installing the touch screen, the release film 220 and the protective film 230 need to be torn off through the first handle part 221 and the second handle part 231. The second handle part 231 with the identification coating 232 can enable manual and machine to accurately identify the positions of the first handle part 221 and the second handle part 231, avoiding the situation of missed tearing of the release film 220 and the protective film 230

[0026] Please refer to Figure 3 , in an embodiment, the release film 220 is set as a colored release film. With this setting, when installing the touch screen, it can enable manual or machine to identify whether the release film 220 is torn off

[0027] In one embodiment, the color of the identification coating 232 is set to be different from the color of the release film 220. This setting makes it easier for humans or machines to identify the position of the second handle portion 231.

[0028] Please refer back to Figure 3 , in one embodiment, the release film 220 is a heavy release film, and a relatively large force is required to tear off the heavy release film, which avoids changing the position of the release film 220 while tearing off the protective film 230 when the IR hole 240 needs to be tested for transmittance.

[0029] Please refer back to Figure 3 , in one embodiment, the adhesive layer 210 is a double-sided adhesive foam. The double-sided adhesive foam has a strong adhesive force, which can ensure the firmness of the adhesive layer 210.

[0030] Preferably, the protective film 230 is a transparent protective film.

[0031] Please refer back to Figure 3 , in one embodiment, the side of the protective film 230 close to the release film 220 is adhesively set. In this way, it is easier to tear off the protective film 230 and cover it back in place.

[0032] Please refer to Figure 1 , in one embodiment, the first handle portion 221 and the second handle portion 231 are arranged outside the cover plate 10, which enables humans or machines to quickly identify the positions of the first handle portion 221 and the second handle portion 231, so that the release film 220 and the transparent film can be quickly torn off.

[0033] Please refer back to Figure 1 , in one embodiment, the side of the first handle portion 221 close to the second handle portion 231 is non-adhesively set, which avoids the first handle portion 221 and the second handle portion 231 from sticking together, and enables the protective film 230 to be quickly torn off when the IR hole 240 needs to be tested for transmittance.

[0034] Please refer back to Figure 1 , in one embodiment, a circuit board 300 is provided on the cover plate 10. The circuit board 300 is a flexible circuit board, and the flexible circuit board has the characteristic of being bendable, which avoids interference caused by the circuit board 300 when tearing off the release film 220 and the protective film 230.

[0035] The above embodiments only represent several embodiments of the present invention. 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 noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
