ABSTRACT:
The present invention provides a unique method of making a barrier rib structure for a plasma display panel. Instead of employing the traditional screen printing method of making barrier ribs, the present invention employs a section of low temperature cofired ceramic dielectric. The unique method includes the steps of providing a fusible dielectric composition in an organic binder, applying the composition on a glass sheet, applying a photoresist composition, placing a mask over the coated plate to provide a pattern of openings in the photoresist corresponding to the pattern of the picture subcells, using a laser to remove the portions of the coating not covered by the photoresist to form the color subcells and heating the resulting assembly to a sintering temperature to fuse the dielectric composition to form the barrier rib structure and to fuse the barrier rib structure to the glass plate.
