Abstract
Official abstract text for this publication.
A vacuum fluorescent display apparatus comprising a filament cathode ( 10 ) and an anode ( 7 ); the filament cathode being arranged in a vacuum container, and used for releasing low-energy electrons; the anode having a phosphor ( 8 ) adhering thereto, and being struck by the low-energy electrons and thereby caused to emit light; wherein a structural body ( 9 ) is provided to a region in which the low-energy electrons released by the cathode can be controlled; the structural body having an electrically conductive or semi-conductive metal oxide formed at a portion that is bombarded by low-energy electrons.
First claim
