MULTI FUNCTIONAL 3 LAYERS OPTICAL FILM FOR BACK LIGHT UNIT

摘要

PURPOSE: A multi functional three multi-layer optical film for back light unit are provided to implement durability against thermal transformation or bending and dispersion and collection of the light by manufacturing a sheet and acrylic sheet to be a three multi-layer. CONSTITUTION: A multi functional three multi-layer optical film for back light unit is formed by collecting diffusion convex micro lens(5) of hemispherical. The convex micro lens of hemispherical is a three multi-layer and has light diffusion characteristic. The three multi-layer is formed by stacking a polycabonate sheet(1) and an acrylic sheet(2).
