Abstract

A dispenser system for a liquid crystal display panel includes a table, a rotatable plate on the table, a substrate disposed on the plate, the substrate having a plurality of first image display parts and a plurality of second image display parts, and at least one syringe supplying a sealant material onto the substrate to sequentially form a plurality of first seal patterns and a plurality of second seal patterns, wherein each of the plurality of first seal patterns are formed along outer edge portions of the first image display parts and each of the plurality of second seal patterns are formed along outer edge portions of the second image display parts.

Claims (18)

1. A dispensing method for a liquid crystal display panel, comprising:

loading a substrate onto a plate on a table, the substrate having a plurality of first image display parts and a plurality of second image display parts;

supplying a sealant material onto the substrate to form a plurality of first seal patterns along each outer edge portion of the plurality of first image display parts;

rotating the plate on the table to rotate the substrate on the table; and

supplying the sealant material onto the substrate to form a plurality of second seal patterns along each outer edge portion of the plurality of second image display parts.

2. The method according to claim 1 , wherein each of the plurality of first image display parts have a first area size and each of the plurality of second image display parts have a second area size different from the first area size.

3. The method according to claim 1 , wherein the forming of a plurality of first seal patterns comprises:

forming short side portions of the plurality of first seal patterns by supplying the sealant material onto the substrate using a plurality of syringes having a first alignment while the table is driven along a direction parallel to a shorter side of the substrate; and

forming long side portions of the plurality of first seal patterns by supplying the sealant material onto the substrate using the plurality of syringes having a second alignment while the table is driven along a direction parallel to a longer side of the substrate.

4. The method according to claim 3 , wherein the forming short side portions of the plurality of first seal patterns and the forming long side portions of the plurality of first seal patterns are alternately performed.

5. The method according to claim 3 , further comprising changing the first alignment of the plurality of syringes to the second alignment after rotating the substrate.

6. The method according to claim 5 , wherein the substrate is rotated by about 90°.

7. The method according to claim 3 , further comprising changing the first alignment of the plurality of syringes to the second alignment during rotating the substrate.

8. The method according to claim 7 , wherein the substrate is rotated by about 90°.

9. The method according to claim 1 , wherein the forming of a plurality of second seal patterns comprises:

forming short side portions of the plurality of second seal patterns by supplying the sealant material onto the substrate using at least one syringe while the table is driven along a direction parallel to a shorter side of the substrate; and

forming long side portions of the plurality of second seal patterns by supplying the sealant material onto the substrate using the at least one syringe while the table is driven along a direction parallel to a longer side of the substrate.

10. The method according to claim 9 , wherein the forming short side portions of the plurality of second seal patterns and the forming long side portions of the plurality of second seal patterns are alternately performed.
