Claims
- 1. A method for fabricating an anode plate for a field emission display (FED) having phosphor and gettering material thereon, comprising the steps of:
- providing an optically transparent insulating plate;
- depositing an electrically conducting layer being optically transparent on a principle surface of said insulating plate;
- patterning by masking and etching said conducting layer forming an array of parallel conducting stripes on said insulating plate;
- selectively coating a mixture composed of a first phosphor and a gettering material on every third a conducting strip in said array of conducting stripes, and thereby forming a first array of pixels composed of said mixture on said electrically conducting stripes;
- selectively coating a mixture composed of a second phosphor and said gettering material on an array of conducting stripes adjacent to said first array of pixels, and thereby forming a second array of pixels;
- selectively coating a mixture composed of a third phosphor and said gettering material on the remaining array of conducting stripes, and thereby forming a third array of pixels;
- baking said insulating plate having said array of pixels formed from alternating stripes of said first, second and third phosphors containing said gettering material, and thereby completing said anode plate.
- 2. The method of claim 1, wherein said electrically conducting layer is composed of indium tin oxide (ITO).
- 3. The method of claim 1, wherein said selective coating is performed by electrophoresis in a bath containing a slurry composed of said phosphors and gettering material.
- 4. The method of claim 1, wherein said gettering material is a composition of zirconium, vanadium and iron (Zr-V-Fe).
- 5. The method of claim 1, wherein said first, second and third phosphors are a red, green and blue phosphor.
