Abstract
This paper presents a range of new autostereoscopic 3D display systems based on Liquid Crystal Display (LCD) technology in which observer tracking has been used to allow comfortable viewing freedom. For high image quality the Twin-LCD display has been used while other work has been in progress with flat panel displays using a new arrangement of LCD pixels. For each system the observer tracking system is described. In the flat panel display, a novel means to track such a display with no moving parts has been developed.
