摘要： The present invention includes a low voltage, high current density, large area cathode for scrubbing of cathodoluminescent layers. The cathodoluminescent layers are formed on a transparent conductive layer formed on a transparent insulating viewing screen to provide a faceplate. An electrical coupling is formed to the transparent conductive layer to provide a return path for electrons. The faceplate and the cathodoluminescent layers are placed on a conveyer in a vacuum. The cathodoluminescent layers are irradiated with an electron beam having a density of greater than one hundred microamperes/cm2. The electron beam may be provided by a cathode including an insulating base, a first post secured to the insulating base near a first edge of the insulating base and a second post including a spring-loaded tip secured to the insulating base near a second edge of the insulating base. The cathode also includes a first wire cathode having a first end coupled to the first post and a second end coupled to the spring-loaded tip of the second post. The first wire cathode is maintained in a tensioned state by the spring-loaded tip. The electron irradiation scrubs oxygen-bearing, species from the cathodoluminescent layer. Significantly, this results in improved emitter life when the faceplate is incorporated in a field emission display. The display including the scrubbed faceplate has significantly enhanced performance and increased useful life compared to displays including faceplates that have not been scrubbed.

摘要： A method for evacuating and sealing a field emission display package and an improved field emission display package are provided. The field emission display package includes a face plate, a back plate and a peripheral seal formed between the face plate and back plate of a low melting point seal material such as indium or an alloy of indium. Within the sealed package components of a field emission display are mounted. These include a display screen formed on the face plate and a base plate flip chip mounted to the face plate. The peripheral seal is formed during a sealing and evacuating process performed in a reaction chamber at a reduced pressure. During the sealing and evacuating process the seal material is compressed. In addition, the sealing and evacuating process can be performed at approximately room temperature or alternately at temperature near the softening point of the seal material.
