Abstract: A field emission backlight for a display device includes upper and lower substrates. The upper substrate includes an upper transparent substrate, a transparent electrode, and a fluorescent part. The lower substrate includes a lower transparent substrate having a receiving groove, a first electrode part, a second electrode part, and an electron-emitting part. The first electrode part is formed on an upper surface of the lower transparent substrate and the second electrode part is formed on a bottom surface of the receiving groove, so that the gap between the first and second electrode parts can be reduced below that conventionally required. This, in turn, enables the level of a voltage applied between the first and the second electrode parts to be reduced, and a corresponding reduction in the manufacturing cost of a field emission backlight to be achieved.

Abstract: Field emission nanostructures assist operation of a microdischarge device. The field emission nanostructures are integrated into the microdischarge device(s) or are situated near an electrode of the microdischarge device(s). The field emission nanostructures reduce operating and ignition voltages compared to otherwise identical devices lacking the field emission nanostructures, while also increasing the radiative output of the microdischarge device(s).

Abstract: A method of generating light comprising the step of applying an electric field to an excimer-forming gas such as a gas mixture containing noble gases and hydrogen or halogen, and providing free electrons in the gas. The electric field is configured to accelerate electrons to at least the energy required to form excimers, but in at least one region of the electric field, the field does not substantially ionize the gas, so that the field does not induce arcing through the gas. For example, electrons can be injected from one or more field emission electrodes (18) such as one or more a metal needle tip conductors, whereas the electric field can be a field between the field emission electrodes and a counterelectrode (13).
