High Transmittance Brightness Enhanced Optical Element for LCD by Wholly Coating Process |
摘要 |
A high transmittance brightness enhanced optical element for backlight modules and liquid crystal display device is disclosed. The brightness enhanced polarizing optical element comprises a reflective polarizer film, a phase retardation film, and a polarization enhancement film. The reflective polarizer film provides a function of selectively reflecting right-handness circularly polarized light or left-handness circularly polarized light and will transmit the other one of them. The one was selectively reflected will be recombined with the light source or the backlight and re-direct toward the reflective polarizer. The portions of the reflective light will be recombined with the fresh light from the light source as above and the processes repeatedly. As a result, almost all of the light transmit the reflective polarizer and in the same circular polarization. The light is then transmitted the phase retardation film and converted to a polarized light with another optical axis.
