Abstract
A transparent emissive display is created using a transparent anode and a transparent cathode so that images can be viewed from both sides of the field emission display panel. When the phosphor material emits the image, it can pass through the field emission material, if such a material is effectively made transparent by the manner in which it is deposited. The cathode conducting layer and the cathode substrate are thus also made transparent. Alternatively, multiple displays can be stacked together.
Claims6
A field emission display comprising:
- a transparent cathode further comprising:
- a transparent substrate;
- a transparent conductor layer deposited on the transparent substrate;
- and
- a field emitter effectively transparent and deposited on the transparent conductor layer;
- and
- an anode further comprising:
- a phosphor for emitting light in response to bombardment by electrons emitted from the field emitter,
- wherein the light emitted from the phosphor passes through the transparent cathode.
