Single substrate, vacuum fluorescent display

A single substrate, vacuum fluorescent display comprising:

• a supporting substrate;
• a first layer of electrically conductive material positioned on the substrate:
• a light emitting layer including phosphor positioned on the first layer;
• a substantially centrally located opening defined through the light emitting layer with portions of the light emitting layer substantially surrounding the centrally located opening;
• a layer of dielectric material positioned in the centrally located opening of the light emitting layer;
• a second layer of electrically conductive material positioned on the dielectric layer, the second layer of electrically conductive material being electrically insulated from the first layer of electrically conductive material;
• and
• an electron emitting layer of low work function material positioned on the second layer of electrically conductive material and further positioned so that emitted electrons strike the portions of the light emitting layer extending outwardly from the dielectric layer.

A single substrate, vacuum fluorescent display comprising:

• a supporting substrate;
• rows of metal positioned on the substrate;
• light emitting material including phosphor positioned on the rows of metal so as to define a plurality of pixels;
• a layer of dielectric material positioned on a centrally located portion of each of the pixels with portions of light emitting material at each pixel extending outwardly therefrom;
• columns of metal positioned on the dielectric layers so as to define junctures with the rows of metal at each pixel;
• and
• an electron emitting layer of low work function material positioned on the columns of metal at each pixel and further positioned so that electrons emitted by the emitting layer at each pixel strike the outwardly extending portions of light emitting material adjacent thereto.
