Abstract

Die flache Bildwiedergabevorrichtung besteht aus einem wannenförmig ausgebildeten Leuchtschirm 9 aus Glas auf der Vorderseite mit einer inneren Leuchtschicht, einem metallischen Kolben 1 als Rückseite und einer plattenförmigen Steuerstruktur 8 zwischen einer flächenhaften Kathode 7 und der Leuchtschicht. Um die Seitenwände 13 des Leuchtschirmes 9 ist ein Implosionsschutz 14 angeordnet. The flat image display device consists of one tub-shaped fluorescent screen 9 made of glass on the Front with an inner layer of light, a metallic bulb 1 as the back and a plate-shaped Control structure 8 between a flat cathode 7 and Luminous layer. Around the side walls 13 of the fluorescent screen 9 an implosion protection 14 is arranged.
