Viewing zone expansion of autostereoscopic display with composite lenticular lens array and saddle lens array

The light field display technology can reconstruct the virtual three-dimensional scene with high precision, providing users a highly immersive viewing experience without any auxiliary equipment. However, one of main challenges faced by this is narrow view (FOV). In paper, we present novel autostereoscopic utilizing Composite Lenticular Lens Array (CLLa) and Saddle (SLa). By time-division quadruplexing, distinct contents are assigned to different pairs zones. optical model scheme simulated ZEMAX. FOV expanded horizontally 100 degrees crosstalk level reduced 0.8%. It worth noting that both zones share same set pixels, which theoretically results in spatial resolution times higher than traditional schemes. Furthermore, has been partially verified 7.9-inch TFT-LCD screen, experimental demonstrate an effective expansion angle more 16.2% compared
