Abstract

The invention provides a naked-eye three-dimensional display device, and the device comprises a display part which comprises a display unit array formed by the array arrangement of a plurality of display units; and a visual angle regulation and control device which comprises a harmonic diffraction lens array formed by arranging a plurality of harmonic diffraction lens sub-units in an array mode, wherein each harmonic diffraction lens sub-unit corresponds to one display unit, the harmonic diffraction lens sub-units of the harmonic diffraction lens array are divided into a plurality of groups, light rays emitted by the same group of harmonic diffraction lens sub-units converge into the same viewpoint, and light rays emitted by different groups of harmonic diffraction lens sub-units convergeinto different viewpoints. In this way, different three-dimensional display effects can be seen at different visual angles, and the utilization efficiency of light can be improved.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a naked-eye three-dimensional display device. Background technique [0002] As one of the main sources of information for human beings, vision is particularly important in daily life. Unlike natural scenes, traditional display devices can only present two-dimensional images at present. This lack of depth of plane information to a certain extent limits human exploration and cognition of the vast world. Studies have shown that almost 50% of the human brain is used to participate in the processing of visual information, and the presentation of two-dimensional images leads to a decrease in brain utilization. Glasses-free 3D (three dimensional, 3D) display has great application value in film and television, games, education, vehicle, aviation, medical treatment, and military affairs. Taking the military field as an example, the visualization of 3D images is requir...
