Abstract:
A method of manufacturing a display device having a substrate with barrier ribs, comprising:providing a substrate having a substrate surface; providing frit material; providing a squeegee having a contact portion comprising a front surface, a rear surface opposite the front surface, a contact surface, and a groove structure including grooves opening onto at least the front surface and the rear surface; positing the substrate and the squeegee such that the contact surface of the squeegee is positioned against the substrate surface, the groove structure at the front surface has a cross-sectional front groove profile in a plane perpendicular to a longitudinal direction parallel to the substrate surface, the groove structure at the rear surface has a cross-section a rear groove profile in another plane perpendicular to the longitudinal direction, and the front groove profile has greater cross-sectional area than the rear groove profile; and moving at least one of the squeegee and the substrate in the longitudinal direction relative to the other of the squeegee and the substrate while the contact portion of the squeegee is in contact with the substrate surface, resulting in a pattern of barrier ribs of the fit material on the substrate surface, the barrier ribs extending in the longitudinal direction and having a cross-sectional rib profile perpendicular to the longitudinal direction corresponding with the rear groove profile.
