Method for orienting a parallax barrier screen on a display screen

A method for orientating a parallax barrier screen on a display screen with pixels in a grid of rows i and columns j to produce a display screen for three-dimensional representation, the method comprising:

• temporarily applying a positioning marker approximately on an image area of the display screen;
• observing the positioning marker via a camera, the positioning marker being imaged via at least one deflection mirror, the image taken by the camera being shown on a monitor that also contains a positioning marker approximately in a middle of an image area of the monitor;
• relatively orientating the display screen such that in the image on the monitor both positioning markers are aligned and also limiting edges of the image area of the display screen in the image on the monitor appear parallel to the limiting edges of the image area of the monitor;
• removing the positioning marker from the image area of the display screen;
• positioning the parallax barrier screen in front of the image area of the display screen;
• displaying a test image via the pixels with rows i and columns j, which have different views A(k) with k=1, n and n=6 or n=7;
• observing the displayed test image through the parallax barrier screen from a defined distance by the camera, the image taken by the camera being shown on the monitor;
• and
• orientating the parallax barrier screen in front of the display screen via the image displayed on the monitor.
