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 second stage at the stage slider and configured to receive a test substrate or a main substrate thereon; 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 to enable modification of the patterns of the discharged organic drops, and configured to discharge the modified patterns onto the main substrate.

2 . The display panel manufacturing device of claim 1 , wherein the second stage comprises a test substrate placing unit configured to place the test substrate on the second stage.

3 . The display panel manufacturing device of claim 2 , wherein the test substrate placing unit comprises a test substrate heating unit configured to heat the test substrate to harden the organic drops.

4 . The display panel manufacturing device of claim 1 , further comprising test substrate raising and lowering units located at the second stage and configured to separate the test substrate from the second stage.

5 . The display panel manufacturing device of claim 1 , further comprising a substrate providing unit configured to move in a longitudinal direction of the stage slider and configured to load the test substrate onto the second stage or to unload the test substrate from the second stage.

6 . 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 the organic drops discharged onto the test substrate.

7 . The display panel manufacturing device of claim 6 , further comprising a third stage facing the drying unit and configured to receive the test substrate thereon.

8 . 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.

9 . The display panel manufacturing device of claim 8 , wherein the patterning unit 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.

10 . The display panel manufacturing device of claim 8 , 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 the patterns of the organic drops discharged onto the test substrate.

11 . The display panel manufacturing device of claim 10 , further comprising a fourth stage located at a lower surface of the pattern analyzer and configured to receive the test substrate, on which the patterns of the organic drop are formed, thereon.

12 . The display panel manufacturing device of claim 1 , further comprising aligned marks at the second stage.
