Abstract (en)
[origin: WO2009039800A1] The invention relates to a method for orienting a parallax barrier screen on a display screen with picture elements x(i,,j) in a grid comprising rows i and columns j for the purpose of producing a display screen for three-dimensional representation. This involves the following steps being performed: temporary application of a positioning marker (6a), observation of the positioning marker (6a) by means of a camera (3), relative orientation of the display screen (1), removal of the positioning marker (6a), positioning of the parallax barrier screen (2) in front of the picture area of the display screen (1), display of a test picture, which comprises various views A(k), where k = 1,...,n and n = 6 or n = 7, on the picture elements x(i,,j) with rows i and columns j, observation of the displayed test picture through the parallax barrier screen (2) by means of the camera (3), orientation of the parallax barrier screen (2) in front of the display screen (1). The method according to the invention can be carried out quickly and is therefore suitable for industrial use for the manufacture of display screens for three-dimensional representation.
