Novel depth-fused display (DFD) system with wide viewing 3D images

Abstract

Viewing angle caused by images shift is the most serious issue for depth-fused display (DFD). A wide viewing angle 3D-DFD system utilized high collimated backlight with wide viewing angle micro-lens array was proposed to avoid the images shift. From the experiment results, the viewing angle was demonstrated to be increased to theta = +/-30 degrees similar to +/-40 degrees, which is much wider than that of conventional DFD (theta<+/-10 degrees). Consequently, the proposed 3D-DFD system will be glasses-less, fatigue-less, and wide viewing.
