Products Description
Batwing Diffuser Film Product Introduction
Batwing Diffuser Film is an innovative optical diffuser film, centered around a unique batwing structure. Through sophisticated microstructuring, it achieves superior light diffusion performance. This unique structural design not only effectively improves light uniformity but also softens and creates a more natural light distribution. Made from environmentally friendly, optical-grade raw materials, this film boasts high light transmittance and low haze, making it suitable for a wide range of display and lighting applications, delivering a premium optical experience to users.
Batwing Diffuser Film Advantages
Efficient Light Diffusion:
The batwing-shaped microstructure evenly scatters incident light at multiple angles, increasing light uniformity to over 90%, effectively eliminating flare and dark areas for a more even light distribution.
High Light Transmittance:
Utilizing an advanced optical material formula, the film achieves a light transmittance of over 92% while maintaining excellent diffusion, minimizing light energy loss and enhancing the brightness of displays and lighting.
Lightweight and Durable:
The film's thickness is only 0.1-0.3mm, making it easy to install and integrate. Its excellent flexibility and scratch and abrasion resistance ensure long-term stable use in challenging environments, extending the product's lifespan.
Environmentally Friendly and Safe:
Halogen-free and heavy metal-free materials are used, complying with international environmental standards such as RoHS and REACH, ensuring no harm to the environment or human health during production and use.
High Customization: The film's color, thickness, haze, diffusion angle, and other parameters can be flexibly customized to meet the individual needs of different applications.
Batwing Diffuser Film Production Process
Raw Material Preparation:
Selected optical-grade polycarbonate (PC) and polyethylene terephthalate (PET) base materials are added in precise proportions to functional additives such as light diffusers and antioxidants, and then uniformly mixed using high-speed stirring.
Extrusion:
The mixed raw materials are conveyed to a twin-screw extruder, where they are melted and plasticized under high temperature and pressure. The materials are then extruded through a die to form a continuous film sheet. This process requires strict control of temperature, pressure, and extrusion speed to ensure uniform film thickness.
Microstructure Forming:
Using a precision roll-pressing process, an embossing roller with batwing-shaped microstructures is used to emboss a high-precision microstructure pattern onto the film surface. The embossing process requires precise control of pressure, temperature, and speed to ensure that the shape, size, and spacing of the microstructures meet the design requirements.
Drawing and Cooling:
The formed film is stretched by a draw roller to adjust its dimensions and properties. It then passes through a cooling roller for rapid cooling and stabilization of the film's physical properties.
Slitting and Inspection: After cooling, the film is slit into specified sizes according to customer requirements and undergoes a comprehensive inspection. Inspection criteria include light transmittance, haze, thickness uniformity, and microstructure accuracy to ensure that each roll meets quality standards. Finally, the film is packaged and shipped.
Batwing Diffuser Film's Four Applications
Liquid Crystal Display (LCD):
Used in the backlight modules of LCD screens, it effectively diffuses backlight light, improves brightness uniformity, eliminates bright lines and dark corners, and enhances image quality. It is widely used in devices such as TVs, computer monitors, and tablets.
LED Lighting:
Using Batwing Diffuser Film in LED lamps gently diffuses the high-brightness LED light source, reducing glare and creating a comfortable lighting environment. It is suitable for indoor, commercial, and educational lighting applications.
Advertising Light Boxes:
It evenly distributes light from LED strips within the light box, creating clear, bright, and shadow-free advertising images, enhancing the visual appeal and longevity of the advertising.
Automotive Interior Lighting:
Used in areas such as vehicle dashboards and interior ambient lighting, it evenly and softly diffuses light, creating a comfortable and upscale interior lighting environment while minimizing driver visibility and improving driving safety.
