ABSTRACT:
A flat-panel display contains an emissive cathode structure and a generally flat encapsulating body that surrounds the cathode structure to form a sealed enclosure. The cathode structure contains electronegative atoms (22), which consist of oxygen and/or fluorine, chemically bonded to a carbon-containing cathode (10). Atoms (24R) of electropositive metal are chemically bonded to the electronegative atoms.
