Patent

CA 2174962

Field emitter flat display, having an inner vacuum space wherein there are housed: a) a layer of excitable phosphors and a plurality of microcathodes (MT), which emit electrons driven by a high electric field; and b) a plu- rality of electric feedthroughs (P) and a vacuum stabilizer (G). Said vacuum stabilizer (g) is essentially formed of a porous supported layer of a non-evaporable getter material, 20 to 180 µm thick, housed in a zone essentially free from microcathodes, phosphors and feedthroughs.

Ecran plat à émission de champ possédant un vide interne renfermant (a) une couche de luminophores excitables et plusieurs microcathodes (MT) émettant des électrons entraînés par un champ électrique puissant; et (b) plusieurs traversées électriques (P) et un stabilisateur de vide (G). Ledit stabilisateur de vide (G) est essentiellement formé d'une couche poreuse sur support, composée d'une matière de dégazage non évaporable ayant une épaisseur de 20 à 180 mu m et placée dans une zone essentiellement exempte de microcathodes, de luminophores et de traversées.
