Observer tracking is provided in an autostereoscopic 3D display, for instance of the type including an LCD panel 2 behind a parallax barrier. An infrared sensor such as a position sensitive detector is provided on the LCD panel. The parallax barrier extends over the detector so as to form an image of the observer or of a reflective target worn by the observer on the detector. The parallax barrier is moved so as to keep the image at a constant position on the detector. The viewing zone thus track the observer.
