Laser Phosphor Display

Laser Phosphor Display

Ein Laser Phosphor Display (LPD) ist ein Bildschirm, der aus einer Matrix von Laserdioden besteht, die jeweils auf ihren Bereich des Bildschirms mit Hilfe von beweglichen Spiegeln einen Bildausschnitt zeichnen.[1]

Inhaltsverzeichnis

Aufbau und Funktionsweise

Der Bildschirm besteht aus einem Kunststoff-Glas-Hybrid-Material, das mit farbigen Phosphorstreifen beschichtet ist. Der Laser zeichnet den Bildausschnitt (analog zu einem Elektronenstrahl in einer Kathodenstrahlröhre) Zeile für Zeile von oben nach unten. Durch das ultraviolette Laserlicht werden die unterschiedlichen Phosphorschichten angeregt und dadurch Photonen emittiert.
