In order to eliminate the Moiré fringe and crosstalk existed in parallax barrier based autostereoscopic display, a new design of slanted zigzag staggered parallax barrier was presented for autostereoscopic display. The slits were divided into sections at half the height of a pixel and the adjacent two sections were symmetrical triangles based on slanted barrier. This method can decrease the probability of the perceived adjoining sub-pixel seen through the same slit when compared with the slanted barrier, thererfore, crosstalk can be reduced and the field of viewing zone can be extended. The simulated and measured results show that the proposed method can increase the viewing zone by 25% more than that of slanted barriers with a decrease of only 4.5% of the Moiré fringe. And it has higher practical value for autostereoscopic display.
