The laminated silvered reflector (LSR) is a reflection film used in backlight units (BLU) of mobile phones, which largely reflects downward light emitted from the BLU towards LCD for light recycling, resulting in higher-intensity upward light and the increase of LCD screen brightness.
Features
The reflector, with a total thickness of about 80 μm, comprises a reflective layer of 1-1.5 mil (a silver-plated PET overcoat), a protective layer of 1.5-2 mil (a transparent, white, black or silver PET substrate), and a 5-7 μm adhesive layer of high light transmittance formed by an optically clear adhesive (OCA). Coated on one surface of the reflector is a dust-free and abrasion-resistant protective film of 40-50 μm. The reflector has an average reflectance of at least 95% across the wavelength range of 460-700 nm. Such a high reflectivity is achieved by the sliver-plated layer, which, with a fine surface finish, just resembles a reflective mirror and significantly increases the upwards luminous flux.
