The present invention relates to a method of displaying first content and second content on an autostereoscopic display device, wherein the method comprises an improved procedure for determining precise positions of sub-pixels in a pixel arrangement of an autostereoscopic display. For the most common display panel in which adjacent red, green and blue sub-pixels are uniformly distributed in the row direction at an interval of 1 / 3 of the pixel size, the conventional implementation method has a very good effect. However, many novel display panels appearing in the market have a poorly regular arrangement of sub-pixels, which complicates the programming of autostereoscopic display devices. The method of the invention solves this problem by defining a set of pixels forming a repeating unit (imprint) in a sub-pixel arrangement and translating sub-pixel locations in the repeating unit into all sub-pixel locations in the entire pixel arrangement. In this way, the invention also provides a universal method for determining the positions of sub-pixels in a pixel arrangement, which is applicable regardless of the arrangement of the (sub-) pixels. In this way, software of the autostereoscopic display device can easily accommodate panels with different pixel arrangements. This makes it easier to construct a workable autostereoscopic display device using different panels.
