Products Description
Anti-blue light diffusion film Product Introduction
1. Basic Concepts and Core Functions
Anti-blue light diffusion film, also known as anti-blue light diffusion film, is a new type of optical film material developed specifically for modern electronic display devices. It combines two core functions: blue light blocking and light diffusion. The blue light blocking function precisely filters harmful blue light in the 400-480nm wavelength range emitted by electronic screens, reducing its harmful effects on the eyes. The light diffusion function, through a special optical structure, evenly disperses direct light, eliminating screen glare and glare.
2. Technical Principles and Material Composition
This film uses high-quality optical-grade polyester (PET) film as a base material, coated with a special functional coating. The coating contains blue light absorbers that selectively absorb harmful blue light, while light-diffusing particles redirect light for uniform diffusion. Furthermore, the coating utilizes a special resin formula to ensure a stable bond between the components. Through sophisticated coating and curing techniques, the film possesses excellent optical properties and durability.
3. Wide Range of Applications
Anti-blue light diffusion film is suitable for a variety of electronic display devices, such as mobile phones, tablets, laptops, monitors, and TVs. Whether used for daily office work or entertainment, or for professional graphic design and video editing, it effectively protects users' eyes and enhances their visual experience. In education, it can also be used on electronic whiteboards and student tablets to reduce the adverse effects of blue light on adolescents' vision.
4. Differentiated Advantages Compared to Traditional Products
Compared to ordinary screen protectors, anti-blue light diffusion film not only protects the screen but also prioritizes protecting the user's eyesight. Compared to simple anti-blue light films, it not only blocks blue light but also improves light distribution, reducing reflections and glare. And compared to simple diffusion films, it adds anti-blue light functionality, providing more comprehensive visual protection, making it an ideal choice for users who seek healthy eyes and a superior visual experience.
Advantages of Anti-Blue Light Diffusion Film
Highly Effective Blue Light Blocking:
Utilizing advanced blue light absorption and reflection technology, it blocks harmful blue light in the 400-480nm wavelength range, achieving a blocking rate of up to RG0. This effectively alleviates dry eyes, fatigue, soreness, and other issues caused by prolonged screen time, while reducing potential damage to the retina caused by blue light.
Excellent Light Diffusion:
A micron-scale optical microstructure evenly diffuses direct light, eliminating screen reflections and glare. This ensures clear viewing even in bright sunlight, enhancing image softness and visual comfort.
High Light Transmittance:
While effectively blocking blue light and diffusing light, it maintains high light transmittance, ensuring accurate color reproduction, crisp, bright images, and uncompromising display quality.
Lightweight and Durable:
Available as thin as 0.8mm, its lightweight construction does not add to the thickness or weight of your device. Its excellent abrasion and scratch resistance ensures long-term wear and tear, effectively protecting the screen surface. Environmentally friendly and safe: Made from
Anti-blue light diffusion film production process
Raw material preparation:
High-quality optical-grade polyester (PET) film is selected as the substrate. Specialized coating materials with blue light resistance and diffusion properties, including blue light absorbers, light diffusers, and resins, are also prepared to ensure the quality and stability of the raw materials.
Coating preparation:
The blue light absorbers, light diffusers, and other additives are evenly dispersed in the resin solution according to a precise formula and ratio. A uniform coating solution is prepared through stirring and filtration to ensure consistent optical properties.
Coating process:
Precision coating equipment is used to evenly apply the prepared coating solution to the surface of the PET substrate. Common coating methods include slot coating and roller coating. Precise control of coating speed, temperature, and coating thickness ensures a smooth, uniform coating with minimal thickness tolerance.
Drying and curing:
The coated film enters the drying and curing equipment. Hot air circulation or ultraviolet (UV) irradiation evaporates the solvent in the coating solution, cross-links the resin, and cures it, forming a stable anti-blue light diffusion coating. The drying and curing process requires strict control of parameters such as temperature, time, and light intensity to ensure optimal coating performance.
Slitting and Quality Inspection:
The cured film is slit according to customer requirements into products of varying sizes and specifications. Stringent quality inspections, including testing for blue light resistance, light transmittance, haze, and abrasion resistance, ensure that each roll meets quality standards.
Packaging and Warehousing:
Products that pass quality inspection are packaged using moisture- and dust-proof packaging materials to prevent damage during transportation and storage, and then stored for shipment.
Application Scenarios of Anti-Blue Light Diffusion Film
1. LED Lamps (Table Lamps, Ceiling Lamps, Floor Lamps)
Applications: Study, Bedroom, Children's Room, Office Lighting
Purpose:
Filters the blue light component in LED light sources (traditional LED lamps have a high blue light peak), creating an eye-friendly lighting environment suitable for reading, studying, or relaxing.
Diffuser film softens light, preventing glare (e.g., from a table lamp shining directly into the eyes), and provides more even light distribution for improved comfort.
2. Commercial and Decorative Lighting
Applications: Shopping mall windows, hotel rooms, exhibition halls, bars, etc.
Purpose:
Balances lighting efficiency in commercial spaces, meeting lighting needs while reducing visual fatigue caused by blue light and enhancing the user experience (e.g., hotel room lighting promotes better sleep).
3. Medical Equipment and Instruments
Applications: Hospital examination equipment screens (e.g., ultrasound machines, monitors), operating room lighting. Function:
Reduces blue light exposure when medical staff spend extended periods facing device screens. Operating room lighting filters blue light, reducing visual disturbances and improving precision.
Diffusers ensure uniform lighting and prevent glare from affecting instrument readings.
4. In-Vehicle Displays and Instrument Panels
Applications: Car central control screens, instrument panels, and in-car entertainment systems.
Function:
Filtering blue light while driving reduces eye strain on long drives and improves safety. Diffusers reduce sunlight reflection on the screen, ensuring clear displays.
