Abstract

Zur Kompensation von Geometrieverzeichnungen einer Farbbildröhre, insbesondere eines NS- oder OW-Innenkissens, wird erfindungsgemäß eine Farbbildröhre angegeben, die mit Kompensationsspulen zur dynamischen Korrektur versehen ist. Diese Kompensationsspulen werden vom Ablenkstrom durchflossen, so dass ihr Kompensationsfeld mit zunehmender Ablenkung stärker wird. Im Zusammenspiel mit den statischen Feldern von Korrekturmagneten lässt sich so die verbleibende Innenkissenverzeichnung in NS- und/oder OW-Richtung minimieren oder sogar ganz beseitigen.
