Working principle of the foveated glasses-free 3D display (IMAGE)
Caption
a, State-of-the-art glasses-free 3D display with uniformly distributed information. The irradiance distribution pattern of each view is a dot or a line for current 3D displays based on microlens or cylindrical lens array. b, The proposed glasses-free 3D display with variant distributed information. The irradiance distribution pattern of each view consists of dots, lines, or rectangles. To make a fair comparison, the number of views (16 views) is consistent with Fig. 1a. c, Schematic of a foveated glasses-free 3D display. An LCD panel matches the view modulator pixel by pixel. For convenience, two voxels are shown on the view modulator. Each voxel contains 3×3 pixelated 2D metagratings to generate View 1~View 9.
