A high-resolution autostereoscopic display system with a wide viewing angle using an LCOS projector array

This study develops an autostereoscopic display based on a multiple miniature projector array to provide a scalable solution for a high-resolution 3-D display with large viewing freedom. To minimize distortion and dispersion, and to maximize the modulation transfer function (MTF) of the projection image to optimize 3-D image quality, a dedicated projection lens and an accurate six-axis adjusting platform for the miniature projector were designed and fabricated. Image-blending technology based on a lookup table was adopted to combine images from 30 miniature projectors into a seamless single image. The result was a 35-in. autostereoscopic display with 60 views at a 30 degrees viewing angle, 90 degrees FOV, and large range of viewing distance. The proposed system exhibits very smooth motion parallax when viewers move around in front of it.
