A planar color lamp powered by field emission nanotube emitters and a method for fabricating such lamp are provided. The planar color lamp is constructed with a lamp chamber having at least three spaced-apart, serpentine-shaped emitter stacks formed on a base plate, and at least three spaced-apart, serpentine-shaped fluorescent coating strips formed on a cover plate wherein each of the fluorescent coating strips emits a primary color of red, green or blue when activated by electrons emitted from the nanotube emitter stacks. The nanotube emitter stacks can be advantageously formed by a low cost, thick film printing technique with a material of a mixture of a polymeric binder and nanometer dimensioned hollow fibers such as carbon, diamond or diamond-like carbon material. The present invention planar field emission color lamp provides the advantages of a backlight and color filters into a single compact package that can be fabricated at low cost. |
