In order to study the relationship between tilted angles of parallax barriers and crosstalk quantitatively and seek for the best tilted angle, a simulation model for crosstalk and tilted angles was established based on the optical path equation. Meanwhile crosstalk in front of the screen was simulated in vertical and horizontal directions respectively. The results show that the viewing zone in horizontal direction decreases linearly, however the viewing zone in vertical direction is not in the same case but decreases step by step. Theoretical explanation of the phenomenon was put forward and the quantitative relationship between tilted angle of parallax barrier and crosstalk was obtained. The study would provide a significant guidance for auto-stereoscpoic display based on slanted parallax barrier.
