  • Barrier rib formation
    Patent number: 6358560
    Abstract: In a method of manufacturing a display device, a substrate is provided with a pattern of barrier ribs of frit material by moving a squeegee across a substrate. The barrier ribs extend in a longitudinal direction and have a predefined profile in cross-section which is perpendicular to the longitudinal direction. A contact portion of the squeegee has grooves which correspond in cross-section to the predefined cross-sectional profile of the barrier ribs.

  • Method of providing a pattern of apertures and/or cavities in a plate or layer of non-metallic material
    Patent number: 5804009
    Abstract: After a plate or layer of non-metallic, particularly hard and brittle material has been provided with a (metal) mask having a plurality of apertures arranged in a pattern, it is exposed to at least one jet of abrasive powder particles, which jet is moved relative to the plate. The mask has its surface facing the surface on which the jet impinges secured to the plate or layer of non-metallic material by means of a layer of adhesive material having a thickness which is smaller than the size of the abrasive powder particles.
