Parallax barrier based autostereoscopic display is usually impaired by moire fringe and crosstalk. By using slanted parallax barrier, the moire fringes could be obviously eliminated, but often at the expense of serious image crosstalk. This paper presents a kind of zigzag staggered barrier which can reduce the moire fringe with little impact on the stereo viewing zones. The slits are divided into sections and the adjacent two jagged-edged sections are separated horizontally at a certain distance. This method can reduce the proportion of the perceived black matrix seen through the same slit, which increasing the brightness of the dark part of the moire fringe. In this way widen and weakened moire fringes are acquired. The simulated results show that the minimum perceived moire fringes’ brightness decreases by 108.1% and the viewing zones decreases by 32.8% compared with the vertical parallax barrier. And it has higher practical value for autostereoscopic display.
