Field emission lamp and backlight module using same

Abstract

A field emission lamp includes a substrate, conductive cathode, insulating layer, plurality of emitters, transparent anode, and fluorescent layer. The conductive cathode is formed on the substrate. Each emitter includes a base section and tip section, the tip section being disposed on the corresponding base section. The base sections of the emitters and the insulating layer are integrally created on the conductive cathode. The emitters are perpendicular to the insulating layer. The transparent anode is spaced apart from the emitters. The fluorescent layer is deposited on a surface of the transparent anode and faces to the emitters. Advantageously, the base sections and the insulating layer are made of diamond-like carbon, and the tip section is made of niobium. The field emission lamp has a long life expectancy and an excellent luminescence. This field emission lamp can be used in a backlight module.
