Abstract:
A method for forming ribs in a plasma display panel (PDP), comprising:providing a glass substrate; forming a plurality of address electrodes on the glass substrate; forming a dielectric layer on the address electrodes and the glass substrate; forming and patterning a plurality of sandblasting stoppers above the dielectric layer, the sandblasting stoppers substantially corresponding to the address electrodes, and the width of each sandblasting stopper being not smaller than the width of each address electrode; forming a rib material layer over the dielectric layer and the sandblasting stoppers; forming and patterning a plurality of sand-resists on the rib material layer; sandblasting the rib material layer to form a plurality of ribs and to expose the sandblasting stoppers; removing the sand-resists and the sandblasting stoppers; and performing a sinter process to the dielectric layer and the ribs.
