Abstract
A display panel manufacturing system includes a stage supporting a display panel. A head unit includes nozzles dispensing primary ink onto each of pixels of the display panel. A sensor unit obtains height information of the primary ink dispensed onto each of the pixels. A control unit calculates the amount of ink to be compensated for each of the pixels after the dispensing of the primary ink based on the height information of the primary ink and to control opening and closing of the nozzles. The nozzles additionally dispense the compensating ink onto each of the pixels before the dispensed primary ink undergoes curing.
Claims20
A display panel manufacturing system, comprising:
- a stage supporting a display panel;
- a head unit comprising nozzles dispensing primary ink onto each of pixels of the display panel;
- a sensor unit obtaining height information of the primary ink dispensed onto each of the pixels;
- and
- a control unit calculating an amount of compensating ink to be dispensed onto each of the pixels after the dispensing of the primary ink based on the height information of the primary ink and control an opening and closing of the nozzles,
- wherein the nozzles additionally dispense the compensating ink onto each of the pixels before the dispensed primary ink undergoes curing.
A method of manufacturing a display panel including a plurality of pixels, the method comprising:
- dispensing primary ink onto a display panel using a head unit comprising nozzles;
- obtaining, using a sensor unit, height information of the primary ink dispensed onto each of the plurality of pixels in an area where the primary ink is dispensed by the head unit;
- calculating, using a control unit, an amount of compensating ink to be dispensed based on the height information of the dispensed primary ink;
- determining opening and closing of the nozzles for dispensing the compensating ink;
- and
- dispensing, using the nozzles, the compensating ink additionally onto each of the plurality of pixels before the dispensed primary ink undergoes curing.
