P‐72: An Autostereoscopic Display with a Deep Viewing Zone Using Time‐Multiplexed Directional Backlight

Abstract

We propose a high-resolution autostereoscopic display that has a deep viewing zone based on time-multiplexed directional backlight using a large aperture Fresnel lens. When the distance of a viewer from the display changes, the depth of light source should be changed to avoid stereoscopic crosstalk. By combining a DMD projector with layered PDLC screens, the depth of the light source is electronically changed to follow the viewer's motion, which expands the viewing zone in the depth direction.

33‐3: An Autostereoscopic Display with Time‐Multiplexed Directional Backlight Using an Electroluminescent Display as a Light Source

“…By using an interleaved Fresnel lens array where tiny prisms composing two adjacent linear Fresnel lenses are interleaved in each elemental lens [14][15][16], luminance of backlight becomes uniform without inserting a diffuser, which enables twodimensional direction control of backlight [17,18],…”

70‐2: Viewing Zone Enhancement of Coarse Integral Imaging Using Eye Tracking

“…Recently, for autostereoscopic displays with time-division directional backlight [19][20][21][22], a lens array where the entire lens is interleaved has been proposed to achieve uniformity of backlight luminance [23]. This lens array is characterized by gradual change in the width of elemental prisms, which can also be applied to CII to smooth the discontinuous edges between elemental images, resulting in a more seamless motion parallax [24,25].…”
