Abstract:
1. A stereoscopic image system comprising: a display device which radiates linearly polarized light; glasses comprising a left ocular and a right ocular respectively corresponding to a left eye and a right eye of a user, wherein the left ocular comprises a first left polarizer disposed between the display device and the left eye of the user, a second left polarizer disposed between the first left polarizer and the left eye of the user, and a left polarization plane rotator disposed between the first left polarizer and the second left polarizer of the left ocular, and wherein the right ocular comprises a first right polarizer disposed between the display device and the right eye of the user, a second right polarizer disposed between the first right polarizer and the right eye of the user, and a right polarization plane rotator disposed between the first right polarizer and the second right polarizer; an electronic controller which controls the left polarization plane rotator and the right polarization plane rotator in synchronization with an output image of the display device; and a quarter wave plate disposed between the display device and the first left polarizer of the left ocular and the first right polarizer of the right ocular, wherein a fast axis of the quarter wave plate is inclined at 45 degrees with respect to a polarization axis of one of the first left polarizer of the left ocular and the first right polarizer of the right ocular, and wherein the quarter wave plate comprises a left quarter wave plate and a right quarter wave plate, the left quarter wave plate disposed between the display device and the first left polarizer of the left ocular and the right quarter wave plate disposed between the display device and the first right polarizer of the right ocular.
