Abstract
A dispenser for a liquid crystal display panel includes a table for loading a substrate having at least one image display unit and being horizontally driven in a driving direction of a long side or a short side of the substrate, at least one support member to be horizontally driven in a driving direction perpendicular to the driving direction of the table, and at least one syringe aligned on the support member to supply a dispensing material to the substrate.
Claims5
A dispensing method for a liquid crystal display panel, comprising:
- aligning syringes on first and second support members, respectively;
- loading a substrate on a table, the substrate having image display units;
- supplying a dispensing material to the substrate via the syringes with horizontally driving the table in a driving direction of a short side of the substrate to form first long sides of seal patterns at peripheral regions of the image display units;
- supplying the dispensing material to the substrate via the syringes with horizontally driving the first and second support members in a driving direction of a long side of the substrate to form first short sides of the seal patterns at peripheral regions of the image display units, wherein the substrate is fixed;
- supplying a dispensing material to the substrate via the syringes with horizontally driving the table to an original position to form second long sides of the seal patterns at peripheral regions of the image display units;
- and
- supplying the dispensing material to the substrate via the syringes with horizontally driving the first and second support members to an original position to form second short sides of the seal patterns at peripheral regions of the image display units, wherein the substrate is fixed.

- supplying a dispensing material to the substrate via the syringes of the first support members with horizontally driving the table to an original position to form second long side regions of the odd numbered seal patterns at peripheral regions of the odd numbered image display units;
- supplying the dispensing material to the substrate via the syringes of the first support members with horizontally driving the first support members to an original position to form second short side regions of the odd numbered seal patterns at peripheral regions of the odd numbered image display units, wherein the substrate is fixed;
- supplying the dispensing material to the substrate via a second group of syringes of the second support members with horizontally driving the table in a short side direction of the substrate to form first long side regions of even numbered seal patterns at peripheral regions of the even numbered image display units;
- supplying the dispensing material to the substrate via the second group of syringes of the second support members with horizontally driving the second support members in a long side direction of the substrate to form first short regions of the even numbered seal patterns at the peripheral regions of the even numbered image display units, wherein the substrate is fixed;
- supplying a dispensing material to the substrate via the syringes of the second support members with horizontally driving the table to an original position to form second long side regions of the even numbered seal patterns at peripheral regions of the even numbered image display units;
- and
- supplying the dispensing material to the substrate via the syringes of the second support members with horizontally driving the first support members to an original position to form second short side regions of the even numbered seal patterns at peripheral regions of the even numbered image display units, wherein the substrate is fixed.
