Abstract

Die Erfindung betrifft eine richtungsgesteuerte Beleuchtungseinheit, die Licht von aktivierten Beleuchtungselementen durch ein transmissives Bildwiedergabemittel in Sichtbarkeitsbereiche ablenkt. Die Sichtbarkeitsbereiche werden mit einer Nachführeinrichtungs- und Bildsteuerung den Augen verschiedener Betrachter zu anderen Positionen vor dem Display nachgeführt. Um eine strenge Zuordnung eines Bildpunktes der Bildwiedergabemittel (6) mit einem Ablenkelement (Elektro-Benetzungszelle) eines Ablenkmittels zu vermeiden, enthält die richtungsgesteuerte Beleuchtungseinheit vor dem Bildwiedergabemittel im Lichtweg seriell angeordnete fiächenhafte Beleuchtungsmittel (1), die für die Bildwiedergabemittel homogenes Licht bereitstellen, und Ablenkmittel (3), die mindestens ein Feld mit einer Anordnung von Elektro-Benetzungszellen enthalten, die von der Nachführeinrichtungs- und Bildsteuerung (10) mindestens in Gruppen diskret adressierbar und im Brechungsverhalten einstellbar sind und eine steuerbare Prismenfunktion realisieren, um die Strahlenbündel sequentiell und synchron zu den alternierend modulierten Strahlenbündeln auf die dem aktuell modulierten stereoskopischen Bild zugeordnete Augenposition auszurichten, und zusätzlich eine steuerbare Linsenfunktion realisieren, um die Sichtbarkeitsbereiche abhängig von der Entfernung der Betrachteraugen von den Bildwiedergabemitteln anzupassen.
