Claims
- 1. A field emission display having a baseplate and an opposing face plate, with brightness enhancements, comprising:
- a glass plate, acting as a base for said faceplate;
- a patterned layer of transparent conductive material, which acts as an anode for said display;
- a plurality of phosphorescent elements formed over said anode;
- openings extending between said phosphorescent elements and through said anode;
- said baseplate, formed on a substrate, which is mounted opposite and parallel to said faceplate;
- a reflective, conductive layer over said substrate;
- a plurality of electron-emitting tips formed on said baseplate, extending through openings in said reflective, conductive layer, and formed directly opposite to said phosphorescent elements, and which are divided into smaller groups, or pixels; and
- black matrix material formed over said anode around the periphery of each of said pixels.
- 2. The field emission display of claim 1 further comprising an anti-reflective layer over the interior surface of said glass plate.
- 3. The field emission display of claim 2 wherein said anti-reflective layer is formed only in said openings.
- 4. The field emission display of claim 3 wherein said anti-reflective layer is selected from the group consisting of MgF.sub.12 (magnesium fluoride) and CaF.sub.12 (calcium fluoride).
- 5. The field emission display of claim 4 wherein said anti-reflective layer has a thickness of between about 3000 and 10,000 Angstroms.
- 6. The field emission display of claim 1 wherein said black matrix material is sprayed carbon having a thickness of between about 5 and 20 micrometers.
- 7. The field emission display of claim 1 further comprising spacers with a reflective surface mounted between said faceplate and said baseplate, surrounding each of said pixels, whereby said spacers provide additional reflectivity.
- 8. A field emission display having a baseplate and an opposing face plate, with brightness enhancements, comprising:
- a glass plate, acting as a base for said faceplate;
- a patterned layer of transparent conductive material, which acts as an anode for said display;
- a plurality of phosphorescent elements formed over said anode;
- openings extending between said phosphorescent elements and through said anode;
- anti-reflective material in said openings;
- said baseplate, formed on a substrate, which is mounted opposite and parallel to said faceplate;
- a reflective, conductive layer over said substrate;
- a plurality of electron-emitting tips formed on said baseplate, extending through openings in said reflective, conductive layer, and formed directly opposite to said phosphorescent elements, and which are divided into smaller groups, or pixels; and
- black matrix material formed over said anode around the periphery of each of said pixels.
- 9. The field emission display of claim 8 further comprising anti-reflective material under said anode.
- 10. The field emission display of claim 8 wherein said anti-reflective layer is selected from the group consisting of MgF.sub.12 (magnesium fluoride) and CaF.sub.12 (calcium fluoride).
- 11. The field emission display of claim 8 wherein said anti-reflective layer has a thickness of between about 3000 and 10,000 Angstroms.
