Abstract
A single substrate, vacuum fluorescent display including a first layer of electrically conductive material positioned on a supporting substrate and a light emitting layer including phosphor positioned on the first layer. A second layer of electrically conductive material is supported on the substrate and electrically insulated from the first layer. An electron emitting layer of low work function material is positioned on the second layer and further positioned so that emitted electrons strike the light emitting layer. Since both the electron emitting and the light emitting layers are supported on the substrate, an encapsulating window is simple and easy to construct. Integrated drivers are optionally formed in the supporting substrate.
