摘要:
Provided is an apparatus for driving an inkjet printhead in which a current is applied to a heater to heat ink filled in an ink chamber and expand bubbles so that the ink is ejected from the ink chamber due to the expansive force of the bubbles. The apparatus alternately applies the current to the heater.

An apparatus for fabricating a color filter. This apparatus includes an inkjet head movably installed over a substrate on which a plurality of pixels are formed, discharging ink of predetermined colors into the pixels, and a porous member movably installed over the pixels filled with the ink discharged from the inkjet head, forming a solvent ambient around the ink filled within the pixels due to evaporation of a solvent filled in the porous member, whereby the drying speed of the ink is reduced.

An ink-jet printhead is provided. The ink-jet printhead comprises an ink chamber (102) filled with ink to be ejected, a manifold, which supplies ink to the ink chamber, an ink channel, which connects the ink chamber and the manifold, a nozzle (106) through which ink is ejected from the ink chamber, first and second heaters (108a,108b), which heat ink in the ink chamber and generate bubbles, and a conductor, which is electrically connected to the first and second heaters and applies a current to the first and second heaters. The first and second heaters are disposed to be symmetrical with each other centering on the nozzle, and one of the first and second heaters is disposed toward the ink channel.
