Abstract:
1. A three dimensional image system comprising: a display device configured to suggest a left image and a right image alternately in a frame period; a liquid crystal shutter including: polarized glasses including a right glass window having a first polarization axis and a left glass window having a second polarization axis, wherein the liquid crystal shutter is disposed between the display device and the polarized glasses, wherein the first and the second electrodes are alternately switched between the ON-state and the OFF-state in the frame period such that the left image passes through the left glass window but not the right glass window when the first and second electrodes are in one of the ON-state and the OFF-state and, that the right image passes through the right glass window but not the left glass window when the first and second electrodes are in the other one of the ON-state and the OFF-state, wherein the liquid crystal layer has a phase retardation of (λ/2+α) when there is no electric field between the first electrode and the second electrode, and wherein the liquid crystal layer has a phase retardation of (+a) when an electric field is applied between the first electrode and the second electrode.
