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

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

The present invention relates to: a method for manufacturing a transparent light emitting device, which can minimize the manufacturing time of a large-area high-resolution transparent light emitting device and maximize the productivity thereof by forming an integrated metal mesh circuit pattern through a UV imprinting technology; and a transparent light emitting device manufactured thereby.
