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.
