    Conclusions

    Tabletop 3D light-field display with full parallax based on direction-turning films and views-segmented voxels is demonstrated. In this system, the collimated backlight and the lenticular lens array reversely attached to an LCD panel with a resolution of 7680 pixel×4320 pixel are designed to achieve a 100° horizontal viewing angle, and the direction turning films and the holographic functional screen are applied to reconstruct 3D light-field images within a 90° frontal viewing angle. Views-segmented voxels are first proposed to separate the frontal viewing range into some disparate viewing zones according to the spatial coordinates of different viewers, then the views-segmented image coding method and the mapping function between the views-segmented voxels and sub-pixels on LCD are also deduced. Finally, after the real-time adaptive perspective correction in each viewing zone, a full parallax, high-definition tabletop 3D scene is presented to multiple viewers.
