A nozzle control method and a nozzle control device are provided. The nozzle control method includes: discriminating between the nozzle to eject the ink droplets from the nozzle not to eject the ink droplets; and generating a pressure wave with a predetermined amplitude in the nozzle not to eject the ink droplets when the ink droplets are ejected from the nozzle to eject the ink droplets. Accordingly, it is possible to produce a color filter with a uniform thickness regardless of the print pattern. The ink droplets with a constant size can be ejected when the nozzle pitch of the print head is not the same width as the print pattern width. Therefore, the print quality is improved by a uniformizing ink thickness in which the print job is performed to the print medium regardless of the number of nozzles ejecting the ink droplets concurrently.

Provides are a method of manufacturing a color filter. This method includes the operations of forming a black matrix (120) on a substrate (110), the black matrix defining a plurality of pixels, forming liquid ink layers (131) within the pixels and drying the liquid ink layers, penetrating solvent vapor (170) into the surfaces of the dried liquid ink layers so that the dried ink layers have mobile surfaces i.e. become a fluid, and drying the ink layers (132) having the mobile surfaces.

There is provided a nozzle plate unit (100), inkjet printhead with the same and method of manufacturing the same. In the nozzle plate unit, at least one penetration nozzle (150) is provided, and a heater (140) is disposed around the nozzle to partially change a surface tension of fluid in the nozzle by partially heating the fluid to spit the fluid in a deflected direction. The heater is divided into at least two segments (141,142,143,144) that are disposed around the nozzle with a predetermined distance from the nozzle, each of the two segments being connected with an electrode for an independent operation.

A thermally-driven ink-jet printhead is provided. The thermally-driven ink-jet printhead comprises a substrate (110) on which an ink chamber (106) to be filled with ink to be ejected, a manifold (102) for supplying ink to the ink chamber (106), and an ink channel (104) for connecting the ink chamber (106) and the manifold (102) are formed; first sidewalls (111) and second sidewalls (112), which are formed to a predetermined depth from the surface of the substrate (110) and surround the ink chamber (106) to have a rectangular shape, the first sidewalls (111) being disposed in a widthwise direction of the ink chamber and the second sidewalls (112) being disposed in a lengthwise direction of the ink chamber (106); a nozzle plate (120), which is formed of a plurality of material layers stacked on the substrate and through which a nozzle (108) connected to the ink chamber (106) is formed; a heater (122), which is disposed between the nozzle (108) and each of the first sidewalls (111) inside the nozzle plate (120) to be positioned above the ink chamber; and a conductor (124), which is disposed inside the nozzle plate and electrically connected to the heater (122). Inner surfaces of each of the first sidewalls are uneven, or a pocket is formed in each of the first sidewalls.

A droplet ejector and an ink-jet printhead using the same are provided. The droplet ejector comprises a fluid path through which a fluid (114) moves, a nozzle (110) being formed on one end of the fluid path, a volumetric structure (120), which is formed in the fluid path, is sensitive to an external stimulus, and expands to eject droplets through the nozzle, and a stimulus generator, which applies a stimulus to the volumetric structure. The volumetric structure is formed of stimulus sensitive hydrogel.

An ink-jet printhead and an ink expelling method are provided. The ink-jet printhead includes an ink chamber and an ink channel formed in a passageway plate, an ink ejection hole formed in a cover plate (120) provided on the passageway plate (210), a condenser lens (232) provided at a position corresponding to the ink chamber in the bottom surface of the passageway plate, and laser beam irradiating means for irradiating a laser beam onto ink contained in the ink chamber through the condenser lens; wherein a surface of the ink is vibrated by a pressurized wave generated by the laser beam, and the vibration causes an ink droplet to be expelled from the surface of the ink through the ink ejection hole. The ink expelling method includes filling an ink chamber with ink, irradiating a laser beam onto the ink contained in the ink chamber to generate a pressurized wave in the ink and vibrating a surface of the ink using the pressurized wave, and expelling an ink droplet from the surface of the ink by the vibration.
