Abstract

A display panel manufacturing device including a stage slider, a first stage configured to slide on the stage slider and to receive a test substrate, a second stage on the stage slider and configured to receive a main substrate, and a patterning unit located at a distance from the stage slider and configured to discharge organic drops onto the test substrate, configured to analyze patterns of the organic drops, configured to modify the patterns of the discharged organic drops according to an analysis of the patterns of the organic drops, and configured to discharge the organic drops onto the main substrate.

First claim

What is claimed is:

1. A display panel manufacturing device comprising:
a stage slider;
a first stage configured to slide linearly on the stage slider and configured to receive a test substrate;
a second stage configured to slide linearly on the stage slider independently of the first stage and configured to receive a main substrate; and
a patterning unit located at a distance from the stage slider and configured to discharge organic drops onto the test substrate, configured to analyze patterns of the organic drops, configured to modify the patterns of the discharged organic drops according to an analysis of the patterns of the organic drops, and configured to discharge the organic drops onto the main substrate.

2. The display panel manufacturing device of claim 1 , further comprising test substrate raising and lowering units at the first stage that are configured to separate the test substrate from the first stage.

3. The display panel manufacturing device of claim 1 , further comprising a substrate providing unit configured to load the test substrate onto the first stage, configured to unload the test substrate from the first stage, configured to load the main substrate onto the second stage, or configured to unload the main substrate from the second stage.

4. The display panel manufacturing device of claim 1 , further comprising a drying unit located at a distance from the stage slider and configured to dry organic drops discharged onto the test substrate.

5. The display panel manufacturing device of claim 4 , further comprising a third stage facing the drying unit and configured to receive the test substrate thereon.

6. The display panel manufacturing device of claim 1 , wherein the patterning unit comprises:
a main frame located at a distance from the stage slider and configured to move in a longitudinal direction of the stage slider and in a direction perpendicular to the longitudinal direction; and
one or more drop dischargers located at the main frame and configured to discharge the organic drops onto the test substrate or the main substrate.

7. The display panel manufacturing device of claim 6 , wherein the patterning unit further comprises a pattern analyzer located at the main frame and configured to analyze patterns of the organic drops discharged from the drop dischargers onto the test substrate.

8. The display panel manufacturing device of claim 6 , wherein the patterning unit further comprises a pattern analyzer located at a distance from the main frame and the stage slider and configured to analyze patterns of the organic drops discharged onto the test substrate.

9. The display panel manufacturing device of claim 8 , further comprising a fourth stage located at a lower surface of the pattern analyzer and configured to receive the test substrate thereon after the patterns of the organic drops are formed on the test substrate.

10. The display panel manufacturing device of claim 1 , wherein the first stage comprises aligned marks thereon.

11. The display panel manufacturing device of claim 1 , further comprising a test substrate heating unit inside the first stage to control a surface temperature of the first stage.

12. The display panel manufacturing device of claim 1 , wherein the first and second stages are separated from each other.
