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.
Claims6
Plasma display panel comprising a front plate and a rear plate, leaving between them a two-dimensional matrix of regions filled with a discharge gas, and address means for selectively activating the preselected discharge regions by depositing the electrical charges thereon, wherein it includes a microwave electromagnetic radiation generator for applying, through the said rear plate to all of the said discharge regions, microwave radiation of sufficient intensity to generate plasma discharges only in the activated discharge regions.
