摘要:
Systems and methods for providing an LCD backlight are described. An LCD backlight system includes: a beam bending and viewing film including a first side including a surface diffuser and a second side including a plurality of substantially parallel optical elements, each of the plurality of substantially parallel optical elements including a first facet that includes a refractive surface and a second facet that includes a total internal reflection surface. The systems and methods provide advantages in that light from the LCD backlight is bright and homogenous.
