Multi-Phase Convex Lens Array for Directional Backlights to Improve Luminance Distribution of Autostereoscopic Display

Abstract

We realize homogenous luminance of the directional backlight for the time-division multiplexing autostereoscopic display using a convex lens array with the elemental lenses whose phase of placement in each row differs from one another. The validity of the proposed optical design is confirmed by a prototype system.
