Brightening film (BEF) developed by using 3M patented microreplication technology and multilayer film technology is widely used in liquid crystal display devices of various sizes. 3M multilayer optical film (DBEF for short) is a kind of reflective polarizer, which is composed of several polymer materials and has hundreds of layers, and each layer is only tens to hundreds of nanometers thick. Its innovative multilayer thin film design usually reflects the light absorbed by polarizers in LCD TVs and displays. These reused lights will increase the brightness of LCD, thus reducing the energy consumption required by LCD TVs and displays. Thin brightness enhancement film (BEF) can increase the brightness of LCD by more than two times. After successful product development, it has been widely used in flat-panel TV and electronic equipment industries. Provide brighter, lighter and more power-saving solutions for LCD screens.
