Large-scale three-dimensional (3D) display can evoke audience a great sense of true presence and immersion. Nowadays, most of large-scale autostereoscopic displays are based on parallax barrier with view zone jumping, which also sacrifices much brightness and leads to uneven illumination. With a 3840×2160 LED panel, a large-scale horizontal light field display based on aspheric optical aperture array (AOAA) and holographic functional screen (HFS) is demonstrated, which can display high quality 3D image. The HFS is used to recompose the light distribution. The AOAA is able to improve the quantity of perspective information in horizontal direction by using vertical pixels and it can suppress the aberration that mainly caused by marginal light rays. The 162-inch horizontal light field display can reconstruct 3D images with the depth range of 1.5 m within the viewing angle of 40°. The feasibility of the proposed display method is verified by the experimental results.
