Abstract

A tuned sealing material and a method for attaching a first surface to a second surface using the tuned sealing material are disclosed. In one embodiment, the present invention applies a tuned sealing material between a first surface and a second surface. In this embodiment, the tuned sealing material is comprised of a combination of a filler material and a glass material. Furthermore, in this embodiment, the filler material is tuned to absorb electromagnetic radiation of a selected frequency. Next, in the present embodiment, the tuned sealing material is subjected to the electromagnetic radiation of the selected frequency. As a result of tuning the filler material, the tuned sealing material absorbs the electromagnetic radiation of the selected frequency. After absorbing the electromagnetic radiation of the desired frequency, the tuned sealing material is used to attach the first surface and the second surface.

Claims

1. A tuned sealing material for attaching a first flat panel display surface to a second flat panel display surface, said tuned sealing material comprising:

a filler material; and

a glass material mixed with said filler material, wherein said tuned sealing material is tuned to absorb electromagnetic radiation of a selected frequency with said tuned sealing material disposed between said first flat panel display surface and said second flat panel display surface;

wherein said tuned sealing material is tuned by staining said filler material with an electromagnetic radiation absorbing material selected from the group consisting of copper oxides, ferrous oxides, chrome oxides, and ferrous chromates.

2. The tuned sealing material of claim 1 wherein said glass material is also tuned to absorb said electromagnetic radiation of said selected frequency.

3. The tuned sealing material of claim 1 wherein said tuned sealing material is also tuned by staining said glass material with an electromagnetic radiation absorbing material selected from the group consisting of copper oxides, ferrous oxides, chrome oxides, and ferrous chromates.

4. The tuned sealing material of claim 1 wherein said electromagnetic radiation to be absorbed by said tuning material is selected from the group consisting of visible light, laser light, microwave radiation, ultraviolet light, and infrared radiation.

5. The tuned sealing material of claim 1 wherein said first surface is a backplate of a field emission display device.

6. The tuned sealing material of claim 1 wherein said second surface is a faceplate of a field emission display device.

7. The tuned sealing material of claim 1 wherein said tuned sealing material further includes a plurality of filler materials.

8. The tuned sealing material of claim 7 wherein at least one of said filler materials is tuned to absorb said electromagnetic radiation of said selected frequency.

9. The tuned sealing material of claim 7 wherein more than one of said filler materials are tuned to absorb a plurality of frequencies of electromagnetic radiation.

10. The tuned sealing material of claim 1 wherein said tuned sealing material further includes a plurality of glass materials.

11. The tuned sealing material of claim 10 wherein at least one of said glass materials is tuned to absorb said electromagnetic radiation of said selected frequency.

12. The tuned sealing material of claim 10 wherein more than one of said glass materials are tuned to absorb a plurality of frequencies of electromagnetic radiation.
