1. A multi-viewpoint 3D display screen, comprising:
a display panel, comprising a plurality of composite pixels, wherein each composite pixel of the plurality of composite pixels comprises a plurality of composite subpixels, and each composite subpixel of the plurality of composite subpixels comprises a plurality of subpixels corresponding to a plurality of viewpoints of the multi-viewpoint 3D display screen; and
a grating, directly bonded to the display panel;
wherein a width p of each subpixel of the plurality of subpixels is constructed as:
p≤(d×q)(n×D),
wherein d represents a sum of a thickness of the display panel and a thickness of the grating; q represents a reference distance of an interpupillary distance, D represents a preset viewing distance of the multi-viewpoint 3D display screen, and n represents a refractive index of the grating.
