FIELD EMISSION DISPLAY AND METHOD OF MANUFACTURING THE SAME

摘要

A field emission device (200) comprises a substrate on which an emitter material (270), such as printed CNT paste, is provided. During manufacturing, the emitter material (270) is activated by bringing a patterned mould or stamp (280) comprising an adhesive material into adhesive contact with the emitter material (270). The adhesive contact is such that it provides sufficient adhesive force when the stamp (280) is separated from the material (270), or vice versa, so that at least a portion off the emitter material is removed or rearranged to form a new emission surface on the emitter layer (270). The pattern of the mould or stamp (280) should match that of the emitter structure of the field emission device (200). Preferably, the adhesive material is provided as an adhesive layer on contact surfaces of protrusions of the stamp (280), which is suitable for activating emitter material inside the gate holes (235) of a triode structure for a field emission display.
