Abstract
Device and method for fabricating a display panel having ink-jet printing applied thereto, the device including a stage for supporting a substrate, a base having one or more than one rail for transporting the stage, and one or more than one ink-jet head rotatable by an angel for spraying a pattern forming solution to the substrate, thereby reducing a fabrication cost and simplifying a fabrication process.
Claims26
A device for fabricating a display panel having ink-jet printing applied thereto comprising:
- a stage for supporting a substrate;
- a base having one or more than one rail for transporting the stage;
- and
- one or more than one ink-jet head rotatable by an angel for spraying a pattern forming solution to the substrate.
A device for fabricating a display panel having ink-jet printing applied thereto comprising:
- a stage for supporting a substrate;
- a base having one or more than one rail for transporting the stage;
- and
- ink-jet heads each having a plurality of nozzles for spraying a pattern forming solution to the substrate;
- head controlling means for turning the ink-jet heads by a preset angle according to intervals of patterns intended to form;
- cleaning means for cleaning the ink-jet heads;
- and
- one or more than one camera for monitoring the substrate and the nozzles.
A method for fabricating a display panel having an ink-jet printing applied thereto, comprising the steps of:
- setting ink-jet heads with the ink-jet heads turned by a preset angle with reference to a direction perpendicular to a length direction of the patterns according to intervals of patterns intended to form;
- monitoring positions of the nozzles of the ink-jet heads;
- aligning a substrate on a stage;
- and
- spraying a pattern forming solution onto the substrate through nozzles in the ink-jet heads while moving the substrate.
