Three dimensional image system

摘要

The present disclosure relates to a three-dimensional image system. The present disclosure suggests a three dimensional image system comprising: a display device configured to suggest a left image and a right image alternately; a liquid crystal shutter having a liquid crystal layer and configured to switch between a λ/2 phase retardation state and a 0 phase retardation state; polarized glasses including a right glass window having a first polarization axis and a left glass window having a second polarization axis. According to the present disclosure, the left image and the right image can be exactly recognized by the left eye and the right eye, respectively, without any cross-talk problem.

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:
a first substrate;a first electrode disposed on an inside surface of the first substrate;a second substrate, a second electrode disposed on the second substrate facing with the first substrate;a liquid crystal layer disposed between the first and second electrodes and configured to switch between a λ/2 phase retardation state and a 0 phase retardation state when the electrodes are switched between an OFF state and an ON state; anda compensation film having a phase retardation of a and attached on an outside of the second substrate; and 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.
