A field emission display ( ) includes an electron emitter structure ( ) designed to emit an emission current ( ), a phosphor ( ) disposed to receive at an electron-receiving surface ( ) emission current ( ), and a multi-layered barrier structure ( ) disposed on electron-receiving surface ( ) of phosphor ( ). Multi-layered barrier structure ( ) of the preferred embodiment includes an aluminum layer ( ) disposed on electron-receiving surface ( ) of phosphor ( ) and a carbon layer ( ) disposed on aluminum layer ( ).

A field emission device (100, 150) includes a cathode plate (102, 180) having electron emitters (116), an anode plate (104, 170) having a phosphor (107, 207, 307, 407) activated by electrons (119) emitted by electron emitters (116), and a vacuum bridge focusing structure (118, 158, 218, 318) for focusing electrons (119) emitted by electron emitters (116). Vacuum bridge focusing structure (118, 158, 218, 318) has landings (121, 122, 221, 322), which are attached to cathode plate (102, 180), and further has bridges (120, 220, 320), which extend above and beyond landings (121, 122, 221, 322, 421) to provide a self-supporting structure that is spaced apart from cathode plate (102, 180).

A field emission display (100, FIG. 1) having a stabilized phosphor (110, FIG. 1) includes a cathode plate (130, FIG. 1) having a plurality of field emitters (160, FIG. 1), an anode plate (120, FIG. 1) opposing the cathode plate (130, FIG. 1), and a stabilized sulfide phosphor disposed on the anode plate (120, FIG. 1) to receive electrons from the plurality of field emitters (160, FIG. 1). The stabilized sulfide phosphor includes a sulfide phosphor core containing vacuum-unstable sulfur and a stabilized surface made from a more thermodynamically stable material, which is more thermodynamically stable against outgassing than the vacuum-unstable sulfur of the sulfide phosphor core. The stabilized phosphor (110, FIG. 1) can alternatively include a stabilized oxide phosphor that has an oxide phosphor core containing vacuum-unstable oxygen and a stabilized surface made from a more thermodynamically stable material, which is more thermodynamically stable against outgassing than the vacuum-unstable oxygen of the oxide phosphor core.
