Abstract

Die Erfindung betrifft einen Plasmabildschirm mit einer Frontplatte (1), einer Rückplatte (2) und einer Anzahl von dazwischen angeordneten, durch Trennwände (9) getrennte, Gas enthaltende Plasmazellen (15), in denen sich in einem Plasmabereich (16) ein Plasma zwischen zwei Entladungselektroden (6,7) bilden kann. Bei solchen Plasmabildschirmen wird mittels einer Gasentladung vorzugsweise Strahlung im UV-Bereich erzeugt, die von in den Plasmazellen enthaltenen Phosphorschichten in sichtbares Licht konvertiert werden. Ziel derzeitiger Entwicklungen ist, Plasmabildschirme mit verbesserter Entladungseffizienz und höhrerem Wirkungsgrad zu schaffen. Es wurde erkannt, daß dazu in einem Bereich zwischen den Entladungselektroden, in dem eine hohe elektrische Feldstärke vorherrscht, eine große Anzahl von Elektronen zur Verfügung gestellt werden muß. Erfindungsgemäß sind dazu im Plasmabereich (16) zwischen den Entladungselektroden (6,7) Mittel (20,21,23,27,32) zur lokalen Verengung des Plasmabereichs (16) und/oder zur Verlängerung des zwischen den Entladungselektroden (6,7) liegenden Entladungsweges verglichen mit einem Plasmabildschirm ohne diese Mittel vorgesehen. Dadurch finden sich in einem Bereich hoher Elektronendichte auch gleichzeitig hohe mittlere Elektronenenergien, so daß dort effizient elektrische Energie in Anregungs- und damit in Strahlungsenergie umgewandelt wird.

The invention relates to a plasma screen with a front plate (1), a rear plate (2) and a number of gas-containing plasma cells (15) arranged between them and separated by partitions (9), in which a plasma is located in a plasma area (16) can form two discharge electrodes (6,7). In such plasma screens, radiation in the UV range is preferably generated by means of a gas discharge, which radiation is converted into visible light by phosphor layers contained in the plasma cells. The aim of current developments is to create plasma screens with improved discharge efficiency and higher efficiency. It has been recognized that a large number of electrons must be made available in a region between the discharge electrodes in which a high electric field strength prevails. According to the invention, means (20, 21, 23, 27, 32) are located in the plasma area (16) between the discharge electrodes (6,7) for locally narrowing the plasma area (16) and / or for extending the area between the discharge electrodes (6, 7). discharge path compared to a plasma screen without these means. As a result, high mean electron energies are simultaneously found in a region of high electron density, so that electrical energy is efficiently converted into excitation and thus into radiation energy.
