Abstract
The present invention relates to an optical enhancement film, more specifically, to a cholesteric reflective polarizer film, which is characterized by matching and compensating the emitting spectrum of a white LED backlight for LCD TVs and Monitors. The film not only enhances the brightness of the LED-backlit displays by light recycling effect but also increases the color rendering quality of the LED-backlit displays by phase balancing effect.
