Research on the characteristic of the autostereoscopic LED display (ALEDD) using DOEs sheet is of prime importance to the widely application of the (ALEDD). In this paper, the effects caused by the assembling errors between the LED display and DOEs sheet are theoretically and experimentally analyzed. The results show that, the tolerance assembling errors are |Δ z|≤ 1mm, and, Δθ Δθ ≤ 1°, respectively. This conclusion will benefit a lot in instructing the installation of the autostereoscopic three-dimensional LED display system to reduce the crosstalk and improve the quality of 3D perception.
