Abstract
A luminescent display is provided that comprises: a plurality of individual phosphor elements (13) formed over a glass anode plate (11), and conductive segments (21) formed on each of the individual phosphor elements, wherein each of the conductive segments are electrically isolated from one another and have an anode potential (15) applied thereto.
Claims8
A luminescent display, comprising:
- conductive segments positioned on all individual phosphor elements in the display, the phosphor elements being on an anode plate, and
- a source of anode potential applied to all of the conductive segments through one resistive busbar assembly, the one resistive busbar assembly comprising a conductive bus and one resistive material film;
- wherein all of the conductive segments are connected through the one resistive material film and all of the conductive segments are connected to the conductive bus through the one resistive material film.
An anode comprising:
- an insulating layer on a substrate, said insulating layer having openings that contain luminescent materials, all of the openings containing luminescent material on the substrate being covered with conductive segments;
- and
- a resistive busbar assembly, the resistive busbar assembly comprising a conductive bus and one resistive material film;
- wherein all of the conductive segments are connected through the one resistive material film and all of the conductive segments are connected to the conductive bus through the one resistive material film.
