Abstract
The disclosed mold includes recessed parts which have a shape corresponding to embossed portions of the barrier rib to be fabricated, and protruding parts which have a shape corresponding to depressed portions of the barrier rib to be fabricated, protrude adjacent to the recessed parts, and are tapered. The protruding parts and the recessed parts are arranged at regular intervals. It is possible to simply fabricate the two-layered barrier rib for inkjet application through a single embossing process at low cost using the mold for fabricating the barrier rib of the present invention.
Claims12
A method of fabricating a two-layered barrier rib, comprising:
- (i) applying ink-philic material on a transparent substrate to form a lower ink-philic layer;
- (ii) applying ink-phobic material on the ink-philic layer to form an upper ink-phobic layer;
- (iii) positioning a mold for fabricating the barrier rib on the ink-phobic layer and applying a predetermined pressure thereto to deform material of the ink-phobic layer;
- (iv) radiating UV or applying heat onto a backside of the transparent substrate to conduct curing;
- and
- (v) removing the mold;
- wherein the mold comprises:
- a plurality of protruding parts;
- and
- a plurality of recessed parts,
- wherein, the protruding parts and the recessed parts are arranged at regular intervals, the recessed parts have a shape corresponding to embossed portions of the barrier rib to be fabricated, and the protruding parts have a shape corresponding to depressed portions of the barrier rib to be fabricated, protrude adjacent to the recessed parts, and are tapered, and
- wherein the lower ink-philic layer is arranged between the upper ink-phobic layer and the substrate;
- and said applying the predetermined pressure to deform the material of the ink-phobic layer includes deforming the lower ink-philic layer and the upper ink-phobic layer such that the two-layered barrier rib includes recessed portions that are ink-philic, and tapered projecting portions having tops that are ink-phobic.
