Abstract
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).
