Abstract
A device and method for fabricating a display panel having ink-jet printing applied thereto is disclosed, in which it is possible to simplify fabricating process steps and to reduce production cost, and to prevent pattern failure. The device includes a stag having a hole and supporting a substrate; one or more ink-jet heads having nozzles spraying pattern forming solution onto the substrate; and one or more cameras positioned below the stage so as to monitor the nozzles through the holes.
Claims16
A device for fabricating a display panel having ink-jet printing applied thereto comprising:
- a stage including a hole and supporting a substrate;
- one or more ink-jet heads having nozzles spraying pattern forming solution onto the substrate;
- and
- one or more cameras positioned below the stage so as to monitor the nozzles through the holes.
A device for fabricating a display panel having ink-jet printing applied thereto comprising:
- a stage supporting a substrate having align marks, and having holes for being corresponding to the align marks;
- a plurality of rotary ink-jet heads having nozzles spraying pattern forming solution onto the substrate;
- cameras being fitted below each hole of the stage for monitoring the nozzles through the holes;
- and
- monitors being connected with the cameras so as to monitor the nozzles with grids having a predetermined interval according to an interval between the patterns intended to form.
A method for fabricating a display panel having ink-jet printing applied thereto comprising the steps of:
- (a) setting ink-jet heads;
- (b) monitoring positions of the nozzles of the ink-jet heads by monitoring grids having the predetermined interval according to the interval of the patterns;
- (c) arranging the substrate on the stage;
- and
- (d) spraying pattern forming solution onto the substrate through the nozzles of the ink-jet heads in a state of moving the substrate.
