3D glasses and 3D video playing apparatus

摘要

The present disclosure relates to a pair of 3D glasses and a 3D video playing apparatus. A quarter-wave phase plate is provided at the end of a liquid crystal display (LCD) and the end of the pair of 3D glasses respectively so that the light propagates in the form of the circularly polarized light from a 3D display device to the pair of 3D glasses. Thereby, the technical shortcoming of a decreased luminance of an image or even failure to form an image due to an inappropriate angle included between the pair of 3D glasses and the 3D display device is overcome.
