a Schematic of the full-color video rate 3D displays that contain an LCD panel, a color filter, and a view modulator. b The microscopic image of the RGB 2DMCs on the view modulator. The red dashed line marks a voxel containing 3 × 3 full-color pixels, and the blue dashed line marks a full-color pixel containing three subpixels for R (650 nm), G (530 nm), and B (450 nm). c Photo of the nanoimprinted flexible view modulator with a thickness of 200 µm. d A full-color, video rate prototype of the proposed 3D display. The backlight, battery, and driving circuit are extracted
