Three-dimensional display system based on multi-directional backlight source

The invention relates to the technical field of semiconductors, in particular to a three-dimensional display system based on a multi-directional backlight source, which comprises a face recognition module, a human eye tracking module, a multi-directional backlight source module, a lens module, a liquid crystal module and a control module, the output end of the face recognition module is connected with the input end of the human eye tracking module, the input end of the multi-directional backlight source module is connected with the output end of the human eye tracking module, and the lens module is installed between the multi-directional backlight source module and the liquid crystal module. Light beams emitted by the multi-directional backlight source module pass through the lens module and are imaged on the other side of the liquid crystal module. According to the invention, the sight line information of the user is obtained, and the control module controls the multi-directional backlight source module and
