摘要： An unassisted stereoscopic display device using a directional backlight structure. A directional backlight module (M), a human eye position tracking module (7) and a control interface module are used to enable a flat display screen (6) for common images to produce a stereographic display effect. The directional backlight module comprises a directional optical assembly (9) and an addressable optical engine. According to a time-division principle, the flat display screen (6) alternately displays left and right images viewed by the left and right eyes of a viewer. A video field synchronization time sequence is used to control an on-off time sequence of light-emitting units (10) of the addressable optical engine, and when the left image is displayed, only the light-emitting unit corresponding to the left eye of the viewer is lightened, and when the right image is displayed, only the light-emitting unit corresponding to the right eye of the viewer is lightened. By means of the directional optical assembly (9), a viewing window of the left or right eye is formed by light rays emitted from the light-emitting units (10) in front of the display screen (6), such that the left eye of the viewer can only view the left image and the right eye thereof can only view the right image. Binocular parallax images are fused via the brain to form a stereoscopic image without a loss of resolution.
