Abstract
Three-dimensional (3D) light field display technology became an inevitable future development trend but suffers from insufficient view density. With directional backlight, lenticular lens array, lens array, and holographic functional screen, a new time-multiplexed method is demonstrated to enhance the view density of the light field display. By utilizing a lenticular lens array, the beams through the synchronously refreshed LCD from the sequential directional backlight are converged and time-multiplexed stitched in the focal plane. In addition, the views compression fitting method is proposed further to break the tradeoff between view density and spatial resolution. The experimental findings reveal that the proposed light field display system reconstructs realistic full-parallax 3D images with correct perception and a view density of 1.42 mm−2, and the fitting method enhances the sharpness of the reconstructed 3D scene.
