To perceive a 3D scene by a human visual system (HVS), the display system should be designed to present sufficient depth information for each object such that the HVS can reconstruct each object’s 3D positions. In general, depending on how many viewpoints are provided, the depth cues can be classified into two main categories: monocular and binocular. This chapter discusses different multiplexing methods used in the stereoscopic display. According to how the light-directing mechanism and optical effect are adopted, in general, the chapter categorizes the autostereoscopic display into two major approaches: occlusion-based and refraction-based. As the autostereoscopic display provides one more successful step toward real 3D scene reconstruction, the viewers may further expect to observe motion parallax. Holographic 3D display is a type of display device to reconstruct the optical wave field such that the reconstructed 3D light beam can be seen as the physical presentation of the original object.
