Abstract
An inkjet printing apparatus according to an aspect of the present disclosure may include a first stage, a second stage which is disposed on the first stage and includes a heater, and on which a substrate including a print area is disposed, the print area overlapping the heater when viewed on a plane, a head unit disposed above the substrate, and including a plurality of printheads and an ink supply unit provided to supply, to the printheads, an ink including a material which emits excitation light in response to an electromagnetic wave, and a camera unit which is disposed on a side surface of the head unit and irradiates the ink with the electromagnetic wave and measures the excitation light generated in the ink.
Claims17
An inkjet printing apparatus comprising:
- a first stage;
- a second stage disposed on the first stage, the second stage comprising a heater, a substrate disposed on the second stage, the substrate comprising a print area, the print area overlapping the heater;
- a head unit disposed above the substrate, and comprising a plurality of printheads and an ink supply unit configured to supply the printheads with an ink comprising a material which emits excitation light in response to an electromagnetic wave;
- and
- a camera unit disposed on a side surface of the head unit and configured to irradiate the ink with the electromagnetic wave and measure the excitation light generated by the ink.
A method for manufacturing a display panel, the method comprising:
- providing a first stage;
- disposing a second stage on the first stage, the second stage comprising a heater;
- arranging, on the second stage, a substrate comprising a print area so that the print area overlaps the heater;
- arranging, above the substrate, a head unit comprising a plurality of printheads, an ink supply unit configured to supply the printheads with an ink comprising a material that emits excitation light in response to an electromagnetic wave, and a plurality of nozzles, each disposed on a respective bottom surface of one of the printheads;
- arranging, on a side surface of the head unit, a camera unit;
- discharging the ink to the print area of the substrate through the nozzles to form a first ink pattern;
- using the camera unit to irradiate the first ink pattern with an electromagnetic wave;
- using the camera unit to measure an excitation light of the first ink pattern;
- discharging the ink to an area on the substrate spaced apart from the print area of the substrate to form a second ink pattern;
- and
- curing the second ink pattern to form an emission layer of the display panel.
An electronic device comprising:
- a display device configured to display an image;
- and
- a processor configured to process an image signal and provide the image signal the display device,
- wherein the display device comprises a display panel manufactured by:
- providing a first stage;
- disposing a second stage on the first stage, the second stage comprising a heater;
- arranging, on the second stage, a substrate comprising a print area so that the print area overlaps the heater;
- arranging, above the substrate, a head unit comprising a plurality of printheads, an ink supply unit configured to supply the printheads an ink comprising a material that emits excitation light in response to an electromagnetic wave, and a plurality of nozzles, each disposed on a respective bottom surface of one of the printheads;
- arranging, on a side surface of the head unit, a camera unit;
- discharging the ink to the print area of the substrate through the nozzles to form a first ink pattern;
- using the camera unit to irradiate the first ink pattern with an electromagnetic wave;
- using the camera unit to measure an excitation light of the first ink pattern;
- discharging the ink to an area on the substrate spaced apart from the print area of the substrate to form a second ink pattern;
- and
- curing the second ink pattern to form an emission layer of the display panel.
