Ideal autostereoscopic display designs show a symmetrical light intensity distribution in the viewer's space. Real displays however always show some inhomogeneities. We investigated and simulated an autostereoscopic display with motion parallax barrier. Thereby our newly developed subpixel area model (SAM) served as a basis for barrier and intensity dependent viewing zone calculations. We introduce the implementation of our SAM approach for the simulation of the luminance and the content distribution in viewing distance. Furthermore, a special misalignment of the optical image splitter has been simulated and metrologically compared with the effect of a similar error in an assembled autostereoscopic display. In detail, the truncated shape of the luminous subpixel area under the image splitter, the misalignment and its result have been mathematically described.
