Abstract

L'invention concerne un panneau avant d'écran au plasma améliorant l'efficacité de transmission de la lumière et réduisant remarquablement une tension de commande. Le panneau comprend un substrat transparent, une électrode de soutien, une électrode de bus, une couche diélectrique et un film de protection. On établit un groupe d'extrémités ayant une ou plusieurs nano-extrémités sur une couche diélectrique supérieure en position adjacente qui correspond à l'électrode de soutien, dépassant au moins partiellement du film de protection. Ce groupe est espacé par rapport aux groupes d'extrémités établis sur les électrodes d'entretien adjacentes. Les nano-extrémités d'un groupe sont espacées selon une distance induisant une augmentation de champ. La réduction de la tension de commande réduit l'énergie des ions et des électrons qui entrent en collision avec le film de protection, allongeant la durée de vie du film et des matériaux fluorescents. La réduction de la tension de décharge réduit la tension d'exploitation des différents composants électroniques utilisés dans l'écran au plasma, ce qui réduit les coûts de fabrication.
