[Paper] Autostereoscopy for Two Observers by Adaptive Fractional Time-Division Multiplexing Parallax Barrier

Abstract

We propose an autostereoscopic display allowing two observers with adaptive fractional time-division multiplexing parallax barrier. Fractional time-division suppresses perceived flickers when the order of slit position is properly set. To make sure that both of the observers are located in the proper viewing zones to enable stereoscopy simultaneously, the number of time-division multiplexing is switched in accordance with the distance between them. The viewing zone without crosstalk for the second viewer is evaluated theoretically.
