Description

Technical Field

[0001] The utility model relates to the technical field of backlight sources, in particular to a dustproof protective film structure of a backlight source. Background Art

[0002] During the actual assembly and transportation of LED backlights, the inherent flexibility of the dustproof protective film can easily cause the film to peel off from the adhesive tape. Intentionally increasing the adhesiveness of the dustproof protective film to address this problem can easily cause problems such as tape delamination. This can cause the dustproof protective film to lose its function, allowing foreign matter to adhere to the tape or invade the backlight display area, seriously affecting the pass rate and product processing efficiency. Summary of the Invention

[0003] The purpose of the utility model is to solve the above technical problems and provide a backlight source dustproof protective film structure.

[0004] In order to achieve the above-mentioned technical objectives and meet the above-mentioned technical requirements, the technical solution adopted by the present invention is: a backlight dustproof protective film structure, the dustproof protective film is connected to the backlight source through tape, the dustproof protective film includes a dustproof protective film body, and an extension portion extending beyond the middle frame of the backlight source is provided on one side of the dustproof protective film body, a punching area is provided in the middle of the connection between the extension portion and the dustproof protective film body, and punching grooves are symmetrically provided on both sides of the extension portion, and the areas between the two sides of the punching area and the punching grooves are non-punching areas.

[0005] Preferably, the shape of the punched buckle groove includes but is not limited to a U shape.

[0006] Preferably, the cutting shape of the punching area includes but is not limited to a linear shape, but cannot be a dotted line shape.

[0007] Preferably, the punching area and the bottom edge of the punched buckle groove are in a straight line.

[0008] Compared with the traditional structure, the beneficial effects of the utility model are: simple structure, reasonable design, and the use of local cutting to release part of the reaction force of the dust-proof protective film, thereby weakening the flexibility of the dust-proof protective film itself, effectively improving the automatic peeling phenomenon between the dust-proof protective film and the tape, and improving product quality and work efficiency.

[0012] The utility model is further described below.

[0013] Refer to the attached Figure 1-2 , a backlight dustproof protective film structure, the dustproof protective film 1 is connected to the backlight source through a tape 2, the dustproof protective film 1 includes a dustproof protective film body, an extension portion extending beyond the backlight source middle frame 3 is provided on one side of the dustproof protective film body, a punching area 7 is provided in the middle of the connection between the extension portion and the dustproof protective film body, punching grooves 6 are symmetrically provided on both sides of the extension portion, and there is a non-punching area 8 between the two sides of the punching area 7 and the punching grooves 6.

[0014] In this preferred embodiment, the shape of the punched buckle groove 6 includes but is not limited to a U shape.

[0015] In this preferred embodiment, the cutting shape of the punching area 7 includes but is not limited to a linear shape, but cannot be a dotted line shape. This design will destroy the flexibility of the material of the protective film itself and cause permanent deformation.

[0016] In this preferred embodiment, the punching area 7 and the bottom edge of the punched buckle groove 6 are in a straight line.

[0017] In specific implementation, the dustproof protective film 1 is attached to the top surface of the adhesive tape 2, with an extension extending beyond the outer shape of the backlight middle frame 3. Because there is a height difference between the backlight middle frame 3 and the top surface of the adhesive tape 2, and this height difference cannot be completely avoided, the extension of the dustproof protective film 1 needs to overlap the backlight middle frame 3. The overlap between the dustproof protective film 1 and the backlight middle frame 3 is the starting point 4 for the anti-release force generated by the dustproof protective film's inherent flexibility. The dustproof protective film 1's inherent flexibility transmits the reaction force generated by the height difference to the area where it adheres to the adhesive tape 2, i.e., the point 5 where the dustproof protective film automatically peels off.

[0018] The punched-through area 7 is designed to release some of the reaction force generated by the material's flexibility. The unpunched area 8 is designed to retain some of the dustproof protective film's flexibility, leveraging the material's characteristics to ensure the stability of its shape and prevent uncontrolled deformation. The punched-out groove 6 is designed to sever the connection between the unpunched area 7 and the outer shape of the dustproof protective film 1, also serving to release some of the reaction force generated by the flexibility. By partially severing this reaction force, the automatic peeling phenomenon is resolved. Even after repeated use, such as pulling or peeling, the dustproof protective film will not permanently deform and will remain naturally attached to the backlight middle frame 3, overcoming the automatic peeling phenomenon that occurs between the dustproof protective film and the adhesive tape due to the inherent flexibility of the existing dustproof protective film.

[0019] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the scope of protection of the present invention. All equivalent technical solutions also fall within the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
