[0002] In an integrated touch display module, the backlight module is one of the core components. The backlight module provides light sources for the integrated touch display module. Usually, blind holes need to be set in the integrated touch display module, and cameras are installed through the blind holes. Correspondingly, an imaging hole needs to be opened in the backlight module. To prevent dust from entering the imaging hole, a protective film needs to be attached at the position of the imaging hole. The conventional structure is to simply attach a single plastic film protective film to the back of the backlight module, but this makes it difficult for workers to tear it off. If the protective film extends beyond the shape of the backlight module to add a tear handle, the exposed part of the tear handle is easily lifted by external objects and falls off.

[0003] In view of the above, a backlight module with an easily tearable protective film structure is proposed, which not only ensures that the protective film is easily torn, but also does not fall off due to being lifted by external objects. Summary of the Utility Model

[0022] Figure 4 is Figure 3 Schematic diagram of the stacking structure of the backlight module with an easily tearable protective film structure. Detailed implementation manners

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

[0024] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a backlight module with an easily tearable protective film structure includes: a backlight module body 100 and a protective film structure 200. A camera hole 110 is formed on the backlight module body 100; the protective film structure 200 is attached to the back of the backlight module body 100, and the entire protective film structure 200 is located within the backlight module body 100. The protective film structure 200 covers the camera hole 110; the protective film structure 200 includes a protective film body 210. A heightening block 220 is provided on the side of the protective film body 210 facing the backlight module body 100. The heightening block 220 is used to form an easily tearable gap 230 between one end of the protective film body 210 and the backlight module body 100.

[0025] It should be noted that by arranging the entire protective film structure 200 within the backlight module body 100, that is, making the protective film structure 200 not exceed the outer shape of the backlight module body 100. In this way, it can be avoided that an external object lifts and detaches the protective film structure 100, resulting in the camera hole losing the protection of the protective film body 210; at the same time, a heightening block 220 is provided on the protective film body 210. Through the heightening block 220, an easily tearable gap 230 is formed between one end of the protective film body 210 and the backlight module body 100. In this way, it is convenient for manual tearing of the protective film structure 200 through the easily tearable gap 230, thereby improving the processing efficiency. In this embodiment, the protective film body 210 is a PET (polyester) protective film body. The PET protective film body has relatively high strength and toughness, so it can ensure sufficient protection for the camera hole. Specifically, the backlight module body generally includes a backlight frame and optical film materials. The optical film materials generally include a brightness enhancement film, a light guide plate, a reflection film, etc. A camera hole is formed on the backlight frame, and the protective film structure 200 is attached to the back of the backlight frame.

[0026] Please refer to Figure 1 andFigure 2 As shown, in the first embodiment: the protective film body 210 is provided with a tearing hand portion 211 and a camera hole protection portion which are connected in sequence, and a cushioning block 220 is provided at the camera hole protection portion to form an easy-tear gap 230 between the tearing hand portion 211 and the backlight module body 100, so as to facilitate manual lifting of the protective film body 210 through the easy-tear gap 230; the camera hole protection portion is attached to the area where the camera hole is opened.

[0027] Furthermore, the padding block 220 is a padding double-sided adhesive, and an avoidance hole is opened on the padding double-sided adhesive, and the avoidance hole is used to avoid the camera hole. In this embodiment, the padding double-sided adhesive adopts strong and weak glue, that is, the side of the double-sided adhesive facing the backlight module body 100 is a weak adhesive layer, so as to facilitate the tearing off of the protective film structure as a whole, and the side of the double-sided adhesive facing the protective film body 210 is a strong adhesive layer, so as to ensure the bonding firmness between the double-sided adhesive and the protective film body 210;

[0028] Furthermore, a half-punching line 212 is provided at the junction of the tearing hand portion 211 and the camera hole protection portion, and the half-punching line 212 is used to make the surface of the tearing hand portion 211 form an angle with the surface of the backlight module body 100, that is, because downward pressure is applied to the protective film body during punching, the tearing hand portion 211 will be slightly tilted, so that it is more convenient for employees to grab the tearing hand portion 211 and tear off the protective film structure. Preferably, the diameter of the avoidance hole is larger than the diameter of the camera hole.

[0029] See also Figure 3 and Figure 4 As shown, in the second embodiment: the protective film body 210 is provided with a tearing hand portion 211, a padding block attachment portion and a camera hole protection portion 213 which are connected in sequence, the padding block 220 is arranged on the padding block attachment portion to form an easy-to-tear gap 230 between the tearing hand portion 211 and the backlight module body 100; the camera hole protection portion 213 is attached to the area where the camera hole is opened, that is, the area of ​​the camera hole protection portion 213 is provided with an adhesive layer, so that the camera hole protection portion 213 can be attached to the surface of the backlight module body 100.

[0030] Furthermore, one end of the tearing hand portion 211 is connected to the attachment portion of the padding block 220, and the distance from the other end of the tearing hand portion 211 to the attachment portion of the padding block is 1-5mm, so as to ensure that there is enough area to facilitate tearing off the protective film structure 200; further, the side of the padding block 220 facing the backlight module body 100 is a non-adhesive layer, at which the padding block 220 serves to pad the tearing hand portion 211 of the protective film body to facilitate manual tearing; in the present embodiment, the padding block 220 is a protective paper, and the protective paper can be a colored protective paper to facilitate quick identification of the position of the tearing hand portion 211.

[0031] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof 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 utility model, several modifications and improvements can still be made, and these all fall within 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.
