3D displays have long been recognized as the ultimate dream of display technology development, and many companies and research institutions have been engaged in research in this area for many years. Japan, Europe, America, South Korea and other developed countries and regions have been involved in the development of stereoscopic display technology since the 1980s.
In the 1990s, they began to obtain different levels of research results. Now they have developed stereo glasses and do not need to wear stereoscopic images. Two large stereo display technology systems for glasses. Traditional 3D movies have two sets of images on the screen (from two cameras that are angled at the time of shooting), and viewers must wear polarizers to eliminate ghosting (allowing one eye to receive only one set of images) ), forming a parallax (parallax), resulting in a three-dimensional sense.
