Adaptive glasses-free 3D display with extended continuous viewing volume by dynamically configured directional backlight

Abstract

It is highly challenging for the available glasses-free 3D display to simultaneously possess the advantages of viewing freedom, homogeneous illuminance, high resolution and low crosstalk. This work proposes and demonstrates a directional backlight autostereoscopic display having these advantages with a substantially extended viewing volume and densely packed viewpoints. Low crosstalk and homogeneous illuminance are obtained using dynamically configured directional backlight, realized by a novel system design, in conjunction with viewer’s eye tracking and subsequent backlight control scenario. The autostereoscopy allows the viewers to move around continuously, while the illuminance homogeneity on the screen, high panel resolution and low crosstalk between the left and right eyes are realized, providing high-quality glasses-free 3D display with satisfying viewing experience.
