A novel 3D display approach and system based on spliced images is proposed, which consists of an array of mini‐projectors and a vertical diffuser. We made a prototype‐equipment using 49 mini‐ projectors and a vertical diffuser to demonstrate this method. A 23‐inch LCD screen with the resolution of 1920*1080 and 49 Fresnel lens were used to make the mini‐projector array. This device can display a 3D image with 49 horizontal viewpoints and a small angle pitch of 0.51 °. The 3D images displayed by our approach can be observed at different horizontal and vertical viewpoints without fatigue. The observers will get depth perception from binocular parallax, horizontal motion parallax and vertical motion parallax.
