DISPOSITIVO PER LA VISUALIZZAZIONE DI IMMAGINI DOTATO DI UN PANNELLO DI VISUALIZZAZIONE A SCARICA IN ATMOSFERA GASSOSA E PANNELLO DI VISUALIZZAZIONE A SCARICA,IN ATMOSFERA GASSOSA,PER TALE DISPOSITIVO

A display device having a gas discharge display panel which comprises a plurality of sets of discharge cells (C). Each set (G) comprises N discharge cells (C) arranged according to a matrix of n rows and N/n columns where n>/=2. Each set (G) furthermore comprises first and second electrode means for selectively energizing the N discharge cells (C). The first electrode means comprises N column conductors (A) with n column conductors (A) for each column of discharge cells (C). The column conductors (A) each have a discrete discharge surface element (a) such that in each column of cells (C) each cell (c) has associated therewith for selectively energizing the cell (c) a respective one of the discrete surface elements (a) and a surface element (O) of the second electrode means. Per set (G) the surface elements (O) of the second electrode means are electrically interconnected. The sets (G) are driven successively and in a driven set (G) all discharge cells (C) in accordance with the display information for that set. By simultaneously energizing all discharge cells (C) is a set (G) the duration of operation per cell is increased and an increased brightness is obtained.
