Beschreibung
Zusammenfassung:	According to the invention, a flat panel device includes a faceplate, a backplate made of a co-fired ceramic substrate and attached to the faceplate to form a sealed enclosure, and structure for producing light. The faceplate includes an active region. The light producing structure is divided into a matrix of "display elements," or a plurality of "light producing elements." Driver circuitry is formed on or attached to a surface of the backplate. The driver circuitry is connected to the display elements or light producing elements by electrically conductive vias formed entirely or partially through or within the ceramic substrate, and electrically conductive traces formed within or on one or more surfaces of the ceramic substrate. Each of the display elements or light producing elements is controlled by the driver circuitry to cause light emission at a corresponding pixel or pixels of the faceplate active region.
