Abstract

Bei einem Flachbildschirm, bei dem Elektronen in ei­ nem hinteren Raum (6) erzeugt, durch selektiv geöffnete Löcher einer Elektronenmatrix in einen vorderen Raum (5) geschleust und dort auf einen Phosphorpunkt gelenkt wer­ den, ist das Ablenksystem folgendermaßen gestaltet: Die zeilen- und spaltenparallelen Lochreihen der Elektroden­ matrix werden jeweils von zwei langgestreckten Ablenk­ elektroden (Vertikalablenkelektroden 16, 29 bzw. Horizon­ talablenkelektroden 17, 28) eingefaßt, wobei sich zwischen benachbarten Lochreihen jeweils nur eine einzige Elek­ trode befindet. Ein Dreifarbenbildschirm ist vorzugsweise folgendermaßen ausgeführt: die Zeilenleiter (11) werden nacheinander getastet und bleiben dabei jeweils zwei Bild­ zeilenperioden lang angesteuert; die Spaltenleiter (12) er­ halten während jeder Bildzeilenperiode die zugehörigen Informationssignale, und zwar farbenweise nacheinander; die Vertikalablenkpotentiale werden im Takt der Zeilen­ leiterfortschaltung, jedoch um eine Bildzeilenperiode ver­ schoben, geschaltet; die Horizontalablenkelektrode (17, 28) werden mit der dreifachen Bildzeilenwechselfrequenz an­ gesteuert. Das vorgeschlagene Ablenksystem läßt sich rela­ tiv bequem fertigen, ist überschlagssicher und verlangt kei­ nen besonderen Kontaktier- und Schaltungsaufwand. Hauptanwendungsgebiet: Höchstinformative Displays, ins­ besondere Farbfernsehschirme. With a flat screen, with electrons in an egg nem rear room (6) generated by selectively opened Holes of an electron matrix in a front space (5) smuggled and directed there to a phosphorus point the deflection system is designed as follows: The row and column parallel hole rows of the electrodes matrix are each deflected by two elongated electrodes (vertical deflection electrodes 16, 29 or Horizon talablenkelelektroden 17, 28) bordered, with between adjacent rows of holes each only a single elec trode is located. A three color screen is preferred executed as follows: the row conductors (11) sequentially keyed and remain two images each controlled for long periods; the column conductor (12) hold the associated during each picture line period Information signals, one after the other in color; the vertical deflection potentials are in time with the lines ladder advancement, however, by one picture line period ver pushed, switched; the horizontal deflection electrode (17, 28) are displayed at three times the frame rate controlled. The proposed deflection system can be rela It is easy to manufacture, is rollover-proof and requires no kei special contacting and switching effort. Main area of application: Highly informative displays, ins special color television screens.
