Abstract
Description
Technical Field
[0001] This application relates to the field of brightness enhancement film technology, and in particular to an antistatic brightness enhancement film. Background Technology
[0002] Brightness Enhancement Film (BEF) is an optical film used in liquid crystal displays (LCDs). Its main function is to improve screen brightness and visibility, while optimizing display effects and reducing energy consumption. It uses a special optical structure to control the direction of light propagation, concentrating more light at the front viewing angle, thereby enhancing display brightness.
[0003] Currently, electrostatic brightening films attract dust and particles from the environment, which adhere to the surface of the film or between prism structures, causing dust to scatter light and reduce the light-gathering efficiency of the film. Therefore, this application proposes an antistatic brightening film. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this application is to provide an antistatic brightening film to solve the technical problems in the background art.
[0005] The above-mentioned objective of this application is achieved through the following technical solution: an antistatic brightness enhancement film, comprising a brightness enhancement film body, the brightness enhancement film body comprising an upper brightness enhancement layer and a lower brightness enhancement layer, an antistatic layer further disposed between the upper brightness enhancement layer and the lower brightness enhancement layer, the antistatic layer comprising an upper antistatic layer and a lower antistatic layer, a groove being formed on the side of the upper antistatic layer and the lower antistatic layer close to each other, a conductive fiber layer being placed between the grooves, and adhesives for bonding the upper antistatic layer and the lower antistatic layer being disposed around the grooves.
[0006] By adopting the above technical solutions, the double-layer electrostatic layer design effectively reduces the generation and accumulation of static electricity, lowering the risk of dust adsorption. The conductive fiber layer quickly conducts away static charge to prevent accumulation and keep the surface clean. The adhesive ensures the structural stability of the antistatic layer, preventing displacement or detachment of the conductive fiber layer and enhancing overall mechanical strength. At the same time, the layered design of the brightness enhancement film maintains the original optical performance, and by precisely controlling the thickness and material selection of each layer, the direction of light propagation is effectively controlled, improving screen brightness and visibility. The antistatic layer design minimizes the impact on optical performance. The layered design modularizes the processing and manufacturing process, which is conducive to improving production efficiency, reducing manufacturing costs, and facilitating independent optimization and improvement of different layers. It also enhances environmental adaptability. The stable antistatic performance under various environmental conditions helps extend the service life of the brightness enhancement film and reduce performance degradation caused by environmental factors.
[0007] Furthermore, the adhesive includes an adhesive layer, one side of which is adhered to an upper electrostatic layer and the other side of which is adhered to a lower electrostatic layer.
[0008] By adopting the above technical solution, the adhesive layer can firmly bond the upper and lower electrostatic layers together, forming a stable overall antistatic layer structure. This solid connection helps prevent the upper and lower electrostatic layers from separating or shifting due to factors such as vibration and temperature changes during use, thereby ensuring the overall performance of the antistatic brightening film is stable and reliable.
[0009] Furthermore, an outer base layer is fixedly provided on the outer side of the upper light-enhancing layer, and multiple sets of positioning holes are provided on the outer base layer. Positioning posts fixedly connected to the outer base layer are provided on both sides of the positioning holes.
[0010] By adopting the above technical solution, the design of the positioning holes and positioning posts provides a precise positioning reference for the brightness enhancement film during installation or assembly with other components (such as displays, backlight modules, etc.). The cooperation of the positioning holes and positioning posts ensures that the brightness enhancement film is installed in the correct position, avoiding display degradation or component damage caused by installation deviations.
[0011] Furthermore, an anti-fog layer is fixedly installed on the outer base layer.
[0012] By adopting the above technical solution, the anti-fog layer can effectively prevent fog from forming on the surface of the brightness enhancement film due to water vapor condensation in environments with temperature differences or high humidity, keeping the screen clear and ensuring that the display effect is not affected. By preventing fog formation, the anti-fog layer allows users to obtain a clear and interference-free visual experience under any environmental conditions, especially in humid or variable environments, where this characteristic is particularly important.
[0013] Furthermore, the upper brightening layer and the upper electrostatic layer are bonded together with an adhesive, and the lower brightening layer and the lower electrostatic layer are bonded together with the same adhesive.
[0014] By employing the above technical solution, the layers are firmly bonded together with an adhesive, forming an antistatic brightness enhancement film with a more stable overall structure. This bonding method effectively prevents relative movement or separation between the layers, ensuring the reliability of the brightness enhancement film during long-term use. Using the same adhesive simplifies the manufacturing process, as it eliminates the need to select or adjust different adhesives for different bonding interfaces. This not only improves production efficiency but also ensures consistency and reliability between bonding interfaces, reducing problems caused by adhesive differences.
[0015] Furthermore, a substrate layer is fixedly disposed on the outer side of the lower brightness enhancement layer.
[0016] By adopting the above technical solution, the substrate layer, as the bottom layer structure of the brightness enhancement film, provides solid mechanical support for the entire film. It can withstand a certain amount of external force, preventing the brightness enhancement film from being deformed or damaged due to squeezing, collision, etc. during installation, transportation, or use.
[0017] In summary, this application includes the following beneficial technical effects: The dual-layer electrostatic layer (upper electrostatic layer and lower electrostatic layer) design effectively reduces the generation and accumulation of static electricity through electrostatic shielding and charge dissipation, lowers the risk of dust adsorption, keeps the screen surface clean, and improves the display effect. The conductive fiber layer is placed between the grooves of the upper and lower electrostatic layers to form a conductive network, which can quickly conduct away static charge, prevent static accumulation from damaging electronic components, and at the same time keep the surface of the brightness enhancement film clean, reducing display blurring problems caused by dust adsorption due to static electricity.

An adhesive for bonding the upper antistatic layer 13 and the lower antistatic layer 14 is provided around the grooves.
[0023] The dual-layer antistatic layer design effectively reduces the generation and accumulation of static electricity, lowering the risk of dust adsorption. The conductive fiber layer 15 quickly conducts away static charge to prevent accumulation and keep the surface clean.

[0026] In this embodiment, an anti-fog layer 18 is fixedly disposed on the outer base layer 16. The anti-fog layer 18 can effectively prevent fog from forming on the surface of the brightness enhancement film due to water vapor condensation in environments with temperature differences or high humidity, keeping the screen clear and ensuring that the display effect is not affected. By preventing fog formation, the anti-fog layer 18 enables users to obtain a clear and interference-free visual experience under any environmental conditions, especially in humid or variable environments, this characteristic is particularly important.
[0027] In this embodiment, the upper brightness enhancement layer 11 and the upper electrostatic layer 13 are bonded together with an adhesive, and the lower brightness enhancement layer 12 and the lower electrostatic layer 14 are bonded together with the same adhesive.

Using the same adhesive simplifies the manufacturing process, as it eliminates the need to select or adjust different adhesives for different bonding interfaces. This not only improves production efficiency but also ensures consistency and reliability between bonding interfaces, reducing problems caused by adhesive differences.
[0028] In this embodiment, a substrate layer 17 is fixedly disposed on the outer side of the lower brightness enhancement layer 12. As the bottom layer structure of the brightness enhancement film, the substrate layer 17 provides solid mechanical support for the entire brightness enhancement film. It can withstand a certain amount of external force, preventing the brightness enhancement film from being deformed or damaged due to squeezing, collision, etc. during installation, transportation, or use.
