Abstract
The invention concerns a display panel comprising a front faceplate and a rear faceplate providing between them a two-dimensional matrix of zones filled with discharge gas, addressing means for selectively activating pre-selected discharge zones by depositing therein electric charges, and a device for generating microwave electromagnetic radiation adapted to apply through the rear faceplate to the assembly of the display panel discharge zones, a microwave radiation of sufficient intensity to generate plasma discharges solely in the activated discharge zones. Thus, an easy-to-monitor panel with high luminous efficacy is obtained wherein the addressing and maintenance functions are separate.
