[0062] It should be noted that the display panel displays a two-dimensional planar image, and the relative spatial position relative to the viewing position can be obtained according to different viewing positions. In three-dimensional space, a three-dimensional object can be regarded as composed of light rays emitted by countless tiny discretized point light sources.

[0077] It should be noted that in this embodiment, the expression for obtaining the focal length information of the pixelated harmonic diffraction sub-unit is:

[0078] ;

[0079] In the formula, represents the focal length, represents the radius of curvature of the pixelated harmonic diffraction sub-unit, represents the refractive index, represents the design wavelength;

[0084] ;

[0085] wherein, represents the focal length of the -th imaging, represents the wavelength of the incident light, represents the diffraction order, represents the designed focal length.

[0086] It should be noted that since each pixelated harmonic diffraction sub-unit is non-periodic, each pixelated harmonic diffraction sub-unit has a consistent height.

[0087] S5. Obtain the spatial coordinates of several viewing perspectives, and adjust the positions of several pixelated harmonic diffraction sub-units according to the spatial coordinates and the imaging focal length;

Then, the distance and angle information between the pixelated harmonic diffraction sub-unit can be obtained according to the spatial coordinates of several perspective points, and the positions of the pixelated harmonic diffraction sub-units are adjusted according to the distance, angle information and imaging focal length, so that the 3D image formed by the cooperation of the pixelated harmonic diffraction sub-unit and the display panel is clearer, and there is always a feeling of viewing the image at the best viewing position, further improving the clarity and authenticity of the 3D image.
