Abstract
An autostereoscopic screen for the simultaneous reproduction of more than two different pictures, including a pixel matrix with a multitude of pixels, an optical element arranged on front of or behind the pixel matrix, and a control unit for activating the pixel matrix and the optical element. The optical element forms an optical grid with a family of strip-like structures which run next to one another, wherein a period length of the optical grid is changeable by way of activating the optical element. Thereby, for a change of a viewing distance (Ln, L; L′) the control unit is configured to increase or reduce the period length and to simultaneously change a distribution of picture information onto the pixel matrix. The disclosure further relates to a corresponding method for the simultaneous reproduction of more than two different pictures.
