Stereoscopic display system based on synchronous spatial light modulator

The invention discloses a stereo display system based on a synchronous spatial light modulator. The stereo display system comprises an LED backlight source, a linear lens array, a spatial light modulator array, a linear diffusion film I, a linear diffusion film II, an image display screen, a viewpoint detection module and a synchronous control module. The synchronous control module is used for acquiring a synchronous signal of the image display screen panel, determining a synchronous time sequence by taking the synchronous signal as a trigger signal, and driving the generation of the spatial light modulator array and the on-off of the LED backlight source; the viewpoint detection module acquires space coordinates of the center of each visual area and uploads the space coordinates to the synchronous control module; and the synchronous control module calculates and generates a corresponding light-passing pixel window of the spatial light modulator according to the space coordinates of the left and right visual
