Abstract
A flat panel display and a method for forming a flat panel display. In one embodiment, the flat panel display includes a sealed interior region. The seal material is placed between a faceplate and a backplate. The seal material is heated using microwave energy. The microwave energy melts the seal material, forming a sealed interior region. The flat panel display is evacuated using an evacuation device that is then sealed off. This results in a flat panel display that is hermetically sealed.
Claims30
A method for sealing a faceplate including an active area to a backplate having an active area comprising:
- disposing seal material between said backplate and said faceplate such that said seal material is placed around said active area of said backplate and around said active area of said faceplate;
- and
- applying microwave energy to said seal material such that said seal material melts, bonding said faceplate to said backplate.
A flat panel display having a backplate including an active area and a faceplate including an active area comprising:
- a seal disposed between said backplate and said faceplate and peripherally surrounding said active area said faceplate and peripherally surrounding said active area of said backplate so as to attach said backplate to said faceplate, said seal formed by the application of microwave energy to seal material.
A method for forming a flat panel display having an evacuated enclosure comprising:
- a.) forming a faceplate including an active area having luminescent generating material disposed thereon;
- b.) forming a backplate including an active area which includes electron emitting structures;
- c.) placing seal material on said backplate such that said seal material is placed around said active area of said backplate;
- d.) orienting said faceplate and said backplate such that said active area of said faceplate is aligned with said active area of said backplate;
- e.) applying microwave energy to said seal material so as to melt said seal material and form an enclosure;
- f.) evacuating said enclosure using an evacuation device;
- and
- g.) sealing said evacuation device so as to form a sealed enclosure.
A method for sealing a faceplate having an active area to a backplate having an active area using seal material, said seal material placed between said faceplate and said backplate such that said seal material is placed around said active area of said backplate and around said active area of said faceplate, said method comprising:
- applying microwave energy to said seal material, said microwave energy melting said seal material so as to bond said faceplate to said backplate.
A microwave sealed flat panel display comprising:
- a backplate including an active area;
- a faceplate including an active area;
- an evacuation device;
- and
- a seal disposed between said backplate and said faceplate and peripherally surrounding said active area of said faceplate and peripherally surrounding said active area of said backplate so as to attach said backplate to said faceplate, said seal formed by the application of microwave energy to seal material.
