Abstract: A method for fabricating a carbon-nanotube cold cathode is described. A conductive layer is formed on a substrate, and then a metal film is selectively formed on predetermined emitter regions of the conductive layer. An anodization treatment is done to the metal film to form numerous nanopores through the metal film. Thereafter, carbon nanotubes are deposited into the nanopores through electrodeposition, wherein one end of each carbon nanotube is exposed outside a corresponding nanopore of the metal film.

Abstract: A flat gas discharge lamp includes a first or lower substrate, a plurality of metal electrodes, a dielectric layer, a second or supper substrate, a grid-mesh-shaped spacer, discharge gas and phosphor. The second substrate is parallel with and at an appropriate distance from the first substrate. The grid-mesh-shaped spacer is provided between the first and second substrates. The grid-mesh-shaped spacer defines many discharge cells. The metal electrodes are provided on the first and second substrates, separately or simultaneously. The dielectric layer is provided on the metal electrodes. The discharge gas is put in the discharge cells.
