In order to minimize moiré patterns in autostereoscopic parallax displays, the optical component, which is used for forming viewing zones, analyzed with varying period and slant angle. First, horizontal-parallax displays (HPAD) can be approximated as superposition of three corresponding binary gratings. Referring unification indicial equation method Fourier analysis, a singular state two stable moiré-free states are obtained according equivalent grating LCD special radial grating. Two valid HPAD. For full-parallax (FPAD), grid introduced simulate 2D component progressively Similarly, FPAD eliminating patterns.
