Abstract

Abstract: A polarization modulated directional backlight autostereoscopic display is proposed and demonstrated. The system consists of the orthogonally polarized backlight, the Fresnel lens array, a light shaping diffuser film, and a liquid crystal display (LCD) with a microphase retardation film. The autostereoscopic image pair carried by the directional light with different polarization directions is simultaneously projected to different spatial directions. The simulation and experimental results show that the directional projection of parallax images is realized for a high‐quality autostereoscopic display with large viewing angle and continuous viewing volume, hence making it suitable for practical applications. Abstract : The polarization modulation method is combined with the directional backlight autostereoscopic display (DBAD) technology. The autostereoscopic image pair carried by the directional light with different polarization directions is simultaneously projected to different spatial directions. A high‐quality autostereoscopic display with large viewing angle and continuous viewing volume is realized to avoid blinking and temporal crosstalk.
