Optimizing display uniformity with a staggered backlight in an autostereoscopic display system

In this paper, we propose a staggered design directional backlight system in an autostereoscopic display. Currently, one of the main deficiency of autostereoscopic display is low display uniformity in both horizon and depth direction. In order to optimized display unifomity, the system mainly employs a staggered backlight array designed by a trace-back algorithm and a light shaping diffuser. As result, the horizontal dark areas are fully compensated. Moreover, crosstalk of experimental system is as low as 0.9%.
