[Paper] Autostereoscopic Displays with Time-multiplexed Directional Backlight Using Curved Lens Arrays

Abstract

In this paper, we propose autostereoscopic displays with novel directional backlight designs. A high level of stereoscopic crosstalk is the main problem to be solved in the conventional systems. To reduce crosstalk, we propose a directional backlight system that suppresses the effect of field curvature only with a single layer of curved lens array. It is confirmed that the crosstalk level is reduced notably by the proposed methods. The uniformity of backlight intensity is also increased by using a lens array composed of trapezoid elemental lenses in place of rectangle elemental lenses.
