Patent ID: 6873097

Claim:
A structure comprising: an electron-emitting device which comprises a backplate and an array of laterally separated electron-emissive regions situated over the backplate, each electron-emissive region comprising at least one electron-emissive element; a light-emitting device coupled to the electron-emitting device to form a hermetically sealed enclosure through which electrons emitted by the electron-emissive regions pass to strike the light-emitting device and cause it to emit light that produces an image; and inert gas located in open space of the sealed enclosure, the inert gas consisting of at least one of (a) helium at a partial pressure of at least 2×10 −5 torr and (b) at least one of neon, krypton, xenon, and radon at a partial pressure of at least 5×10 −7 torr.
