摘要
In order to improve the image crosstalk for a film patterned retarder (FPR) of a linear polarizer type in a stereoscopic three dimensional (3D) display, we propose an optical structure with wideband and wide viewing angle characteristics and using only two half-wave retarders. This proposed half-wave retarder of the FPR 3D cell consists of a lambda/2 biaxial film and a patterned lambda/2 A-film. We calculated the phase retardation and confirmed the polarization states of the light passing through each film on the Poincar, over all visible wavelengths by using the Stokes vector and the Muller matrix method. Then, we optimized the optical parameters of the two retardation films in the oblique direction by using the parameter space method as a function of the optical axis and the N (Z) parameter of the biaxial lambda/2 film. Consequently, we verified that the left 3D crosstalk of the proposed FPR 3D cell could be improved by about 91.87% in the horizontal viewing direction and 97.22% in the vertical viewing direction. The right 3D crosstalk could almost maintain the crosstalk value of the conventional structure.
