An embodiment of the present invention provides an inkjet head including: a head body having a storage chamber capable of storing ink; a first inlet pipe and a second inlet pipe connected to the head body and which extend in first different directions and inject the ink in the first different directions; a first outlet pipe and a second outlet pipe connected to the head body and which extend in second different directions and eject the ink in the second different directions; and a nozzle plate positioned under the head body and which includes a plurality of nozzles.

Inkjet head

A method for inkjet printing includes setting a target volume and a target concentration of ink discharged to a pixel, measuring a volume and a concentration of a liquid drop for each of nozzles, selecting first nozzle groups for achieving the target volume, from a volume pool of the liquid drop for each of the nozzles, selecting second nozzle groups for achieving the target concentration, from the first nozzle groups, selecting recipes by combining brightness trend lines, from the second nozzle groups, performing a printing simulation for each of the recipes to select a final recipe, and performing inkjet printing by using the final recipe.

Method for inkjet printing and method for manufacturing display device using the same

An inkjet printing apparatus, method of printing ink using the same and method of fabricating display device are provided. The method of printing ink includes: ejecting ink in which a plurality of particles is dispersed from an inkjet head; irradiating the ejected ink with a first light and a second light having different wavelengths to acquire data on a first exit light and a second exit light emitted from the ink; calculating a concentration of the particles in the ink from the data on the first exit light and the second exit light; and checking whether the concentration is out of an error range from a reference value, where the first light has a wavelength of about 500 nm or less, and the second light has a wavelength of about 1000 nm or more.

Inkjet printing apparatus, method of printing ink using the same and method of fabricating display device

A display device may include a display panel, and first member, and a second member. The display panel has a first section and a second section. The first member includes an electromagnet, extends parallel to the first section and has a first side and a second side. The first side is oriented a first obtuse angle with respect to the second side. The second member directly contacts the first member, extends parallel to the second section, and has a third side and a fourth side. The third side is oriented a second obtuse angle with respect to the fourth side. The first member is connected through the second member to the second section. The second member is connected through the first member to the first section.

Display device and controlling method thereof

A slot die coater planarizing an upper surface of an encapsulation layer and a coating method using the same. The slot die coater includes a slit nozzle configured to supply a coating solution. The slit nozzle includes a hole vertically penetrating a center portion thereof, a first bottom surface disposed at a movement direction side of the slit nozzle with reference to the hole, and a second bottom surface disposed at an opposite direction side of the movement direction of the slit nozzle with reference to the hole. A width of the first bottom surface is different from the width of the second bottom surface.
