Optical principle of white reflective film

White Reflective film is an important backlight components optical film which used for lcd backlight module.

The function of the reflective film is to reflect the light leakage through the light guide plate back to the panel side. Thereby achieving a reduction in light loss.

The optical principle of the reflective film is mainly based on the law of reflection of light.

According to this law, when light encounters the interface between two media, if the incident angle is greater than a critical angle (called the absolute angle of refraction), the light will be completely reflected; if the incident angle is smaller than the critical angle, the light will be along The interface is reflective, and light rays are refracted because the refractive index is different between the inside and outside of the interface.

The reflective film, the incident light first meets the interface of the reflective material, and according to the law of light reflection, most or all of the light will be reflected back. This is why reflectors can reflect light.

FAQ

1. What is a white reflective film?
Our white reflective film is made from optical-grade PET material, designed to efficiently reflect light in backlight units. It is commonly used in LCD modules, LED lighting systems, and display assemblies to enhance brightness and reduce light loss.

2. What are the main applications of your PET reflective film?
Our reflective film is widely used in TVs, laptop screens, monitors, LED light panels, and projector backlight systems. It improves brightness uniformity and energy efficiency in both new assemblies and repair projects.

3. What are the key advantages of your white reflective film?
We offer high-performance reflective film with over 92% reflectivity, excellent flatness, and thermal stability. Made with high-quality PET, it supports long-term use and delivers consistent optical results. Custom sizes and thicknesses are available.

4. How do I properly clean the reflective film?
Use a soft, lint-free microfiber cloth to gently wipe the surface. Avoid using harsh chemicals, alcohol, or rough materials to prevent scratches or damage to the reflective layer.

5. What is the expected service life of your reflective film?
Under normal usage and proper maintenance, our white reflective film can maintain its high reflectivity for many years, making it a durable and cost-effective solution for display and lighting applications.

6. Do you offer customization? What is the minimum order quantity?
Yes, we offer custom sizes to meet your specific requirements. The minimum order quantity (MOQ) is 100 pieces.
