The DF series of optical diffusion films for LCD displays from Fusion Optix offers a wide variety of symmetrical and asymmetrical diffusion profiles with complete control over light output. These films use volumetric diffusion technology, making them more durable, customizable and cost-effective than coated or embossed alternatives. As a bottom diffuser, high transmission results in immediate brightness gain from the backlight. As a top diffuser, superior light management enables tailored viewing angles, Fusion Optix said.
