Abstract

We report on a multiview autostereoscopic display with double-sided reflecting scanning micromirrors. There is a trade-off between the resolution and the number of images in existing multiview stereoscopic displays. In order to solve this problem, we propose the way of projecting time-series pixel data into the discrete directions by using scanning micromirrors. As the number of the view angles depends on the number of pixel data projected in one cycle of the scan, the resolution and the number of the view angles can be independently increased. Double-sided reflecting micromirrors actuated by both external magnetic force and Lorentz force were designed and fabricated based on the MEMS (Micro Electro Mechanical Systems) technology. Fabricated micromirrors are 450 um x 520 um in size, and characteristics of a micromirror, for example the range of the movement and the resonance frequency, were measured. Then the fabricated micromirrors were integrated with a microlens array, pinhole arrays and an LED matrix to construct a prototype of the multiview autostereoscopic display, and the relationship between the view angle and the light intensity was measured. The validity of our proposed method was proved from the light intensity distribution of this prototype.
