Abstract
The plasma matrix display unit comprises a plurality of cathodes perpendicular to a scan anode and to at least one display anode in a gastight enclosure. All the cathodes are positioned on a rear plate. A front plate is transparent at least at the level of points aligned in parallel in the proximity of the display anode. In order to avoid fluctuations of distance between an anode and a cathode during heating operations, longitudinal insulating strips are disposed on the rear plate and form grooves therebetween. The grooves extend under the point lines of the front plate. Each anode is supported on an upper slot of an insulating strip and interacts electrically with the portion of the cathodes emerging from the adjacent groove. The cathodes, insulating strips and anodes are obtained by successive deposition and masking on the rear plate before any further heating. This display unit is designed particularly for the display of large-scale luminous patterns.
