This work presents a new methodology to design patterned circular polarizers consisting of in-cell polarizers, in-cell retarders and biaxial films to achieve very wide viewing freedom for stereoscopic 3D color LCDs. The biaxial films with least materials and simple fabrication concepts are employed for off-axis compensation of the in-cell retarders. In the best result, the crosstalk ratio is less than 0.035 or 0.0082 respectively for over +/- 60 degrees or +/- 40 degrees viewing cone of the 3D display. As to the normal view of the proposed structure with glasses or LCD rotation, the crosstalk ratio is less than 0.11%, with 93.5% improvement as compared with the +/- lambda/4 patterned polarizer. The dispersion properties of materials have been considered in all simulations to mimic real situations. (C) 2010 Optical Society of America
