The stereoscopic display system with good stereoscopic effect, low cost and easy realization is an important direction for the development of the current stereoscopic display technology.

Artificial stereoscopic display methods fall into two broad categories: stereoscopic display (Stereoscopicdisplay) and free display (autosterocopicpisplay). In the stereoscopic display mode, by means of equipment such as glasses, helmets and the like, two eyes of a person respectively see a stereoscopic image pair with parallax at the same time to form stereoscopic vision; most of the free display modes adopt optical plates, so that a viewer can see stereoscopic images without wearing auxiliary equipment.

The stereo realization of the body type display mode mainly comprises three types: time-sharing methods, spectroscopic methods and color-separation methods. The left eye image and the right eye image are separated and displayed through the playing platform, and a viewer wears corresponding glasses when watching, so that the left eye image and the right eye image are received by the left eye and the right eye respectively.
