Abstract

Flache Bildröhre mit Drahtelektrodenebenen zur Führung und Steuerung von Elektronen (Drahtbildröhre) ist eine Vakuumbildröhre bestehend aus einem Glaskolben, einer linienformigen thermischen Kathode mit Gitter und Anode, vier Drahtelektrodenebenen und einer Leuchtstoffschicht. Mit der linienförmigen Kathode, dem Gitter und der Anode werden langsame Elektronene zwischen die Drahtelektrodenebenen in den elektrostatischen Elektronenpfad injiziert, vom Steuergitter zeilenweise abgelenkt und zu einzeinen Strahlen unterteilt und anschließend mit Hochpannung zur Leuchtstoffschicht beschleunigt. Die Bildrohre ist besonders für Fernsehempfänger geeignet. Die Bildschirmgroße reicht vom Kleinformat bis zur Große der derzeit ublichen Braunschen-Fernsenbildrohren. Flat picture tube with wire electrode levels for guidance and Control of electrons (wire picture tube) is a vacuum picture tube consisting of a glass bulb, a linear thermal Cathode with grid and anode, four wire electrode levels and one Phosphor layer. With the linear cathode, the grid and the anode will be slow electrons between the Wire electrode levels in the electrostatic electron path injected, deflected line by line from the control grille and isolated Beams divided and then with high voltage Fluorescent layer accelerates. The picture tubes is especially for Suitable for television receivers. The screen size ranges from Small format up to the size of the currently common Braunschen television tubes.
