[0021] For the convenience of those skilled in the art, the following combines examples and appendices Figure 1To further illustrate the present utility model, the content mentioned in the embodiments does not limit the present utility model.

[0022] Referring to Figure 1 As shown, the present utility model provides a composite brightness enhancement film with a packaging structure 3, which is used to be installed at a corresponding position in the backlight module of a liquid crystal TV; the composite brightness enhancement film includes an optical structure 2 and a packaging structure 3.

[0023] Specifically, referring to Figure 1 and Figure 3 As shown, the optical structure 22 includes a brightness enhancement film body 1, and the brightness enhancement film body 1 includes a first scratch-resistant layer 21, an antistatic layer 22, a first brightness enhancement film layer 23, a second brightness enhancement film layer 24, and a second scratch-resistant layer 25 which are arranged in sequence from top to bottom. In this embodiment, the thickness of the brightness enhancement film body 1 is 200μm to 280μm; both the first brightness enhancement film layer 23 and the second brightness enhancement film layer 24 are made of acrylic resin, and the first brightness enhancement film layer 23 and the second brightness enhancement film layer 24 have the same thickness.

[0024] Specifically, both the upper and lower surfaces of the antistatic layer 22 are adhesively connected to the first scratch-resistant layer 21 and the first brightness enhancement film layer 23 respectively through an acrylate adhesive; both the upper and lower surfaces of the second brightness enhancement film layer are adhesively connected to the first brightness enhancement film layer 23 and the second scratch-resistant layer 25 respectively through an acrylate adhesive.

[0025] Referring to Figure 4 As shown, both the first scratch-resistant layer 21 and the second scratch-resistant layer 25 include an optical polyurethane film 211, a resin adhesive film 212, and a PET film 213 which are arranged in sequence along the direction close to the first brightness enhancement film layer 23. In this embodiment, the first scratch-resistant layer 21 and the second scratch-resistant layer 25 have the same thickness, and are both 30μm to 40μm.

[0026] The optical polyurethane film 211 has excellent wear resistance and scratch resistance, and can effectively resist scratches and abrasions from external hard objects. The PET (polyethylene terephthalate) film has characteristics such as high strength, high modulus, heat resistance, and electrical insulation. In the scratch-resistant layer, the PET film 213 serves as a substrate, providing a solid support for the entire scratch-resistant layer and further enhancing the scratch-resistant effect. At the same time, both the optical polyurethane film 211 and the PET film 213 have a high light transmittance, maximizing the light transmittance and not affecting the optical performance of the composite brightness enhancement film. The resin adhesive film 212 is used to firmly bond the optical polyurethane film 211 and the PET film 213 together, forming a stable structural unit and enhancing the integrity and strength of the scratch-resistant layer.

[0027] Through the provision of the first scratch-resistant layer 21 and the second scratch-resistant layer 25, while ensuring the light-transmitting ability, the surface of the composite brightness enhancement film has excellent scratch-resistant performance, preventing the surface of the composite brightness enhancement film from being scratched or damaged by external hard objects during transportation and installation, which is conducive to maintaining the performance stability of the composite brightness enhancement film and extending its service life.

[0028] The antistatic layer 22 is composed of a number of nano-conductive fibers. The nano-conductive fibers can effectively disperse and conduct static charges, preventing damage to the composite brightness enhancement film or the electronic devices in contact with it caused by static charge accumulation, and at the same time ensuring the stability and reliability of the composite brightness enhancement film during use.

[0029] The first brightness enhancement film layer 23 includes a first substrate and a number of mutually parallel first prism bars provided on the upper surface of the first substrate, and the second brightness enhancement film layer 24 includes a second substrate and a number of mutually parallel second prism bars provided on the upper surface of the second substrate; and the length direction of the first prism bars forms an angle with the length direction of the second prism bars. In this embodiment, the angle between the length direction of the first prism bars and the length direction of the second prism bars is 90°.

[0030] By superimposing the first brightness enhancement film layer 23 and the second brightness enhancement film layer 24, and a certain angle is formed between the length directions of the first prism bars and the second prism bars in the two layers, the light can be refracted and converged more effectively, thereby significantly improving the light utilization rate of the composite brightness enhancement film and the brightness of the outgoing light, making the display effect of the backlight module brighter and clearer.

[0031] Reference Figure 1 and Figure 2 As shown, the encapsulation structure 3 includes a number of positioning holes 31 provided on the brightness enhancement film body 1, a number of hanging ears 32 respectively provided on both vertical sides of the brightness enhancement film body 1, and a number of grooves 33 respectively provided on both horizontal sides of the brightness enhancement film body 1, and mounting holes 321 are provided on the hanging ears 32. In this embodiment, the positioning holes 31 are round holes or waist-shaped holes, and the positioning holes 31 are symmetrically arranged on both side edges of the main film body 11.

[0032] Through the positioning holes 31, precise positioning of the composite brightness enhancement film can be achieved during the assembly process, ensuring its correct alignment with other components of the backlight module (such as light sources, reflectors, etc.). At the same time, by setting the lugs 32 and the mounting holes 321 on the lugs 32, the composite brightness enhancement film can be firmly installed at the corresponding position in the backlight module. And grooves 33 are provided on both sides of the composite brightness enhancement film to cooperate with the corresponding components in the backlight module, thereby realizing the precise positioning, installation and fixation of the composite brightness enhancement film, effectively preventing the phenomenon that the composite brightness enhancement film fails to be fixedly installed at a specific position during installation and is scratched by other components during use, improving the installation efficiency of the composite brightness enhancement film, and further avoiding the performance of the composite brightness enhancement film being affected by scratches during use.

[0033] Wherein, the brightness enhancement film body 1 includes a main film body 11 and folded edges 12 provided at the four peripheral edges of the main film body 11, and the lugs 32 and the grooves 33 are respectively provided at the edges of the corresponding folded edges 12. In this embodiment, during use, the folded edges 12 are all bent inward.

[0034] A first anti-adsorption layer 26 is provided between the first anti-scratch layer 21 and the antistatic layer 22, and a second anti-adsorption layer 27 is provided between the second brightness enhancement film layer 24 and the second anti-scratch layer 25. The first anti-adsorption layer 26 and the second anti-adsorption layer 27 are both filled with silicone particles. Through the setting of the first anti-adsorption layer 26 and the second anti-adsorption layer 27, the anti-adsorption performance of the brightness enhancement film body 1 is enhanced.

[0035] The present utility model provides a composite brightness enhancement film with a packaging structure 3. By setting the first anti-scratch layer 21 and the second anti-scratch layer 25 composed of an optical polyurethane film 211, a resin adhesive film 212 and a PET film 213, while ensuring the light transmission ability, the surface of the brightness enhancement film has excellent anti-scratch performance. At the same time, through the setting of the positioning holes 31, the lugs 32, the grooves 33 and the mounting holes 321, the brightness enhancement film can be precisely positioned and installed at the corresponding position, avoiding the performance of the composite brightness enhancement film being affected by scratches during use.

[0036] The above embodiments are the preferred implementation solutions of the present utility model. In addition, the present utility model can also be implemented in other ways. Any obvious replacement without departing from the concept of the present utility model is within the protection scope of the present utility model.
