High-performance naked-eye light field 3D display

Naked-eye light field three-dimensional (3D) displays reconstruct the light field distribution of objects in space, presenting natural and realistic 3D images that satisfy the stereoscopic visual characteristics of the human eye. However, bottlenecks such as low resolution and shallow depth of field (DOF) have limited the development and application of naked-eye light field 3D displays. In this paper, we propose a high-performance naked-eye light field 3D display. A high-pixel-density Micro-LED array is used to display a light field 3D source, which is then modulated through a projection lens array, a collimating lens array and an aspherical lenticular lens array to reconstruct 3D images. Due to the high pixel density of the light field 3D source and the minimal divergence of the collimated light beams, the reconstructed 3D images have small voxel sizes and faint voxel aliasing. The experimental results demonstrate that the proposed high-performance naked-eye light field 3D display achieves high resolution and large DOF 3D display effects on a 4.05-inch display area, with a DOF of 46 mm.
