Abstract
(EN)
A pair of display electrodes of a gas discharge panel forms narrowest gaps between inner projections provided on a first bus line and an opposite bus line or between the inner projections provided on the first bus line and inner projections provided on the other bus line. Since a discharge is started by the charge concentrated in the narrowest gaps, the firing potential becomes lower than the conventional. The discharge expands gradually to outer projections such that a sustained discharge (surface discharge) can be secured over a wide area. Therefore, a desired scale of discharge improving is achieved while increasing the luminous efficiency.
(FR)
Deux électrodes d'affichage d'un panneau de décharge dans du gaz définissent des espaces très étroits entre les saillants intérieurs présents sur une première ligne de bus et une ligne de bus opposée ou bien entre les saillants intérieurs présents sur la première ligne de bus et les saillants intérieurs présents sur l'autre ligne. Dans la mesure où la décharge est déclenchée par la charge concentrée dans ces espaces très étroits, le potentiel d'ionisation est inférieur à celui que l'on rencontre habituellement. La décharge s'étend graduellement vers les saillants extérieurs de sorte qu'une décharge soutenue (décharge en surface) peut se maintenir dans un grand secteur. On obtient ainsi une échelle désirée d'amélioration de décharge tout en augmentant le rendement lumineux.
