Display panel manufacturing system and method of manufacturing a display panel using the same
A display panel manufacturing system includes a substrate providing module configured to provide a substrate including an active region on which thin-film transistors are disposed, and a peripheral region adjacent to the active region, a test substrate providing module configured to provide a test substrate, an organic film forming module configured to form an ink pattern on each of the substrate and the test substrate, the organic film forming module including a plurality of heads, each of which is configured to drop an ink, an offset inspection module configured to inspect the ink pattern on the substrate, a pattern inspection module configured to inspect the ink pattern on the test substrate, and a droplet inspection module configured to inspect an ink, which is dropped from a head selected from the heads.
1. A method of manufacturing a display panel, comprising:
providing a substrate;
forming at least one ink pattern on the substrate to form an organic pattern; and
inspecting the at least one ink pattern, wherein the inspecting of the at least one ink pattern comprises a pattern inspection step of inspecting an alignment accuracy of the at least one ink pattern, an offset inspection step of inspecting an alignment accuracy between the at least one ink pattern and the substrate, and a droplet inspection step of inspecting an ink, the ink is dropped on the substrate to form the at least one ink pattern,
wherein the inspecting of the ink pattern is performed during the step of forming the organic pattern.
2. The method of claim 1 , wherein:
the at least one ink pattern is formed by dropping an ink from a head to the substrate; and
the inspecting of the at least one ink pattern is performed to adjust a position of the head.
3. The method of claim 2 , wherein:
the pattern inspection step is performed to change a position of the head through a translational motion and a rotational motion on a plan view; and
the offset inspection step is performed to change the position of the head through a translational motion on a plan view.
4. The method of claim 3 , wherein the head comprises a plurality of heads, each of the plurality of heads is independently controlled.
5. The method of claim 2 , wherein:
the head comprises a plurality of heads;
the droplet inspection step is performed to inspect an ink dropped from a single head; and
the single head is selected from the plurality of heads.
6. The method of claim 5 , wherein:
the droplet inspection step is performed to adjust an amount of ink dropped from the selected single head; and
the selected single head is selected in at least one of the pattern inspection step and the offset inspection step.
7. The method of claim 5 , wherein the droplet inspection step is performed to replace the selected single head with a new head.
8. The method of claim 5 , wherein the droplet inspection step is performed using a laser beam.
9. The method of claim 8 , wherein the droplet inspection step is performed using an electronic balance device.
