Analysis of angular dependence of 3‐D technology using polarized eyeglasses

— The cause of the angular dependence of 3-D technology that requires the use of eyeglasses with linear or circular polarization is analyzed. For 3-D technology that requires the use of eyeglasses, anisotropic media such as a polarizer or retardation film determines the polarization state. Therefore, the angular behavior of 3-D display performance is also affected by the characteristics of the anisotropic media that have intrinsic angular dependence. Various conditions of the optic axes of the imaging display and eyeglasses are investigated to understand their effect on 3-D display performance. The result shows that some conditions of the optic axes can cause non-negligible degradation of 3-D display performance.
