✦ Synopsis

An analysis of the basic approaches to autostereoscopic 3D display is presented, together with a discussion of the application of liquid crystal displays (LCDs) in this field. We show that of particular importance in the design of such displays is the illumination optical system and the optical quality of viewing windows produced. The window illumination quality determines many performance criteria including image fidelity, cross talk, viewing freedom and observer dynamics in a wide range of displays. The effects of degradation in window structure are described. Recent progress in 3D systems incorporating two LCD panels based on bulk and micro-optic systems is described. Further a new single LCD flat panel display is described in which observer tracking can be achieved without a requirement for moving parts. We detail the modifications to the LCD pixel structure necessary and how tracking may be achieved by manipulating the video information presented to the display panel.
