Abstract

A display system includes: a display screen having a first display area; a processor configured to modulate laser beams to be emitted from a laser projector according to a pre-stored holographic image data source to obtain modulated laser beams; the laser projector configured to project the modulated laser beams to create a first holographic image in front of the first display area; and at least one photodetector configured to collect first gesture information about a first gesture through which the first holographic image is controlled by a viewer. The processor is further configured to generate a first control signal according to the first gesture information, and re-modulate the laser beams to be emitted from the laser projector, so as to create a second holographic image corresponding to the first control signal.
