Abstract

Light filed 3D display technology precisely reconstructs the light field distribution of objects in space and achieves comfortable and authentic 3D display effects. It has become one of the most promising research in the field of display technology. However, limited resolution and crosstalk affect the viewing experience. Both of these factors significantly impede the advancement of light filed 3D display. This paper presents a high-resolution light field 3D display technology based on optimized divergence angle. The divergence angle of the display light sources is optimized to ±5.37°with a pair of precisely aligned microlens arrays for improving resolution and reducing crosstalk. In the experiments, resolution in different depth planes is effectively enhanced with a compact size. And it has the potential to the application of light field 3D displays in multiple fields such as culture and education.
