US 6,650,052 B1 · Dielectric color filter for AC driven plasma display panel, method for fabricating the same and PDP panel using the same

Abstract

Dielectric color filter for plasma display panel, method for fabricating the same and PDP panel using the same are disclosed. A dielectric color filter for a PDP for which neodymium oxide (Nd2O3), rare earth oxide, is added to an oxide dielectric solid powder having lead glass as a primary ingredient, a resulted material of which is melted and sintered to obtain a dielectric paste, and then the dielectric paste is coated and sintered by screen printing. By applying the dielectric color filter of the present invention to a PDP, the color purity of a fluorescent material can be optimized, and at the same time, the orange color light radiated from the neon discharge gas can be blocked, so that the color purity and the contrast are remarkably improved.

Dependent claims

A plasma display panel, comprising:

an upper panel;
a lower panel spaced apart from and parallel to the upper panel;
sustain electrodes on the upper panel;
a color filtering dielectric layer on the sustain electrodes;
and
barrier ribs on the lower panels, wherein the barrier ribs form discharge cells between the upper and lower panels, and wherein the discharge cells are filled with gas, wherein the color filtering dielectric layer comprises about 5%-10% weight ratio of color filtering oxide, wherein the remainder of the color filtering dielectric comprises about 60 wt % PbO, about 18 wt % Sio2, about 20 wt % B2 O3 and about 2 wt % Al2 O3.
