US Classification:

252500, 2525181, 25251933, 428432

Abstract:

The present invention provides a method for forming a black electrode by performing sintering at a temperature in the range of 500-600 C. after applying a lead-free black conductive composition to a substrate. The aforementioned black electrode comprises a binder comprising a crystallized glass component. The aforementioned black conductive composition comprises conductive particles of black RuO, lead-free black ruthenium-based polyoxide, and mixtures thereof in an amount of 4-30 wt %, based on the total weight of the composition, a lead-free non-conductive black oxide in an amount of 0-30 wt %, based on the total weight of the composition, and a lead-free bismuth-based glass binder in an amount of 10-50 wt %, based on the total weight of the composition.

Abstract:

The invention is directed to black conductive composition(s), black electrodes made from such compositions and methods of forming such electrodes. In particular, the invention is directed to flat panel display applications, including alternating-current display panel applications. Still further, the invention is directed to composition(s) utilizing conductive metal oxides selected from an oxide of two or more elements selected from Ba, Ru, Ca, Cu, Sr, Bi, Pb, and the rare earth metals and photocrosslinkable polymers. These compositions are particularly useful in making photoimageable black electrodes for flat panel display applications.

International Classification:

G03C 1/00

US Classification:

4302811, 4302701, 4302881

Abstract:

The invention is directed to a process and more particularly, to utilizing polymer solutions to make thick film compositions. In one embodiment the process is directed to the formation of photoimageable thick film compositions for use in photo-patterning methods to make photoimageable electrodes in flat panel display applications, including plasma display panels (PDP). Polymer solutions are obtained by directly polymerizing desired monomers in a desired solvent to form a desired polymer, rather than by dissolving a pre-made polymer in a desired solvent. Other ingredients are added to the polymer solution to directly form thick film pastes, including photoimageable thick film pastes.
