According to Human visual characteristics, glasses‐free 3D light‐field display are analyzed. The optimally designed holographic optical element is used to re‐modulate the light distribution with the 3D spatial information, and the clear 3D light field image is perceived. The real‐time interactive 3D light‐field display with the frame rate above 25 fps is realized. The functions of the holographic functional screen and the complex optical device are integrated, and 65inch 3D light field display with the view angel above 100° and acceptable resolution is demonstrated. 162 inch LED based 3D light‐field displays with the continuous viewing angle above 40° and the acceptable resolution are realized. Touchable aerial imaging based floating 3D light‐field displays with the distance of 90 cm from the screen are also demonstrated. Some applications are also discussed.
