An autostereoscopic display using multiple miniature projectors array was developed to realize a 3D display system with both high resolution and large number of views. It is found that image distortion of the projection lens, alignment between the projector and the screen, and image blending among tiled images are the three critical technologies in such a system. This paper presents the researches intended to solve the problems. The result was a 35” autostereoscopic display with 60 views at a 30 view angle, 90 FOV, and large range of viewing distance. The proposed system exhibits very smooth motion parallax when viewers move around in front of it.
