Abstract
The utility model relates to a 3D (Three-Dimensional) display system, which comprises a pair of 3D spectacles and a 3D display device. The left eyeglass and the right eyeglass of the 3D spectacles each comprises a liquid crystal layer and a first polaroid; and the 3D display device comprises a liquid crystal display (LCD) and a second polaroid and further comprises a synchronous signal transmission and reception device, wherein the synchronous signal transmission and reception device is used for transmitting or receiving synchronous signals synchronous to video signals, and converting the synchronous signals into drive signals so as to drive the left eyeglass and the right eyeglass to rotate linearly-polarized light emitted by the 3D display device. Each first polaroid is arranged at the side close to one eye, so that the 3D spectacles only rotate the polarization state of the linearly-polarized light emitted by the 3D display device, do not change the polarization state of the outside natural light passing through the eyeglasses, namely, do not modulate the outside natural light, and then, the outside light source cannot be subjected to flickering; and on the other hand, as the left eyeglass and the right eyeglass of the 3D spectacles in the scheme provided by the utility model each uses only one first polaroid, the transmission rate can be increased by about 20% compared with that of the traditional shutter type spectacles which adopt two polaroids.
