摘要:
A circular polarizer composite including a plane polarizer, a first quarter-wavelength retarder, a cholesteric liquid crystal (CLC) film and a second quarter-wavelength retarder, wherein optical axes of the first quarter-wavelength retarder and the second quarter-wavelength retarder are perpendicularly crossed to each other. Also disclosed is an optical system including the circular polarizer composite and an emissive display module.
摘要:
The present invention provides an optical film composite that includes a linear, reflective polarizing film; a first polymeric substrate layer having birefringence, which is placed on the reflective polarizing film; and a second polymeric substrate layer placed beneath the reflective polarizing film, wherein the optical axis of the first polymeric substrate layer is oriented with respect to the transmission axis of the reflective polarizing film to have of 0° to 25° of an angular difference between the axes. The optical film composite can be employed in LCD devices to improve optical performance.
