摘要： An inkjet head including a plurality of restrictors to reduce crosstalk. The inkjet head includes a channel plate in which an ink channel is formed, an actuator formed on the channel plate, and an ink-supply bezel including a manifold. The ink channel includes an ink inlet to receive ink from the manifold, reservoirs to store ink received through the ink inlet, chambers filled with ink supplied from the reservoirs, nozzles to eject ink filled in the chambers, first restrictors connecting the reservoirs to the chambers, and second restrictors connecting the reservoirs to the ink inlet. Each of the reservoirs includes a first reservoir and a second reservoir that are separated by a central separation wall, and the separation wall includes a third restrictor connecting the first and second reservoirs. Therefore, crosstalk caused by a back flow of ink and transmission of a pressure wave can be prevented during ejection of ink.

摘要： A method of driving a hybrid type inkjet printing apparatus according to example embodiments may use both a piezoelectric method and an electrostatic method. The method of driving may include a plurality of driving modes that are determined by adjusting the order, amplitude, and duration of a piezoelectric driving voltage to a piezoelectric actuator and an electrostatic driving voltage to an electrostatic force applying unit. As a result, ink droplets may be ejected in various sizes and shapes. In a first driving mode, a dome-shaped ink meniscus may be formed at an end portion of a nozzle and ink droplets having a smaller size than the nozzle may be ejected from a surface of the dome-shaped ink meniscus. In a second driving mode, a cone-shaped ink meniscus may be formed at an end of the nozzle, and ink droplets having a smaller size than those of the first driving mode may be ejected from a sharp end portion of the cone-shaped ink meniscus. In a third driving mode, a syringe/cone-shaped ink meniscus may be formed at an end portion of the nozzle and ink in the form of an ink stream may be ejected from a sharp end portion of the syringe/cone-shaped ink meniscus.

摘要： A piezoelectric inkjet head and a method of manufacturing the piezoelectric inkjet head. The piezoelectric inkjet head includes three single crystal silicon substrates bonded to each other. An upper substrate includes an ink inlet, a plurality of pressure chambers, and a plurality of piezoelectric actuators, a middle substrate includes a manifold, a plurality of restrictors, and a plurality of first dampers, and a lower substrate includes a plurality of nozzles. The middle substrate also includes a membrane that is formed under the manifold to mitigate a rapid pressure change in the manifold and if formed of a material different from the material used for forming the middle substrate. A cavity located under the membrane and at least one venting channel that connects the cavity to the outside are formed in the middle substrate or the lower substrate. Due to the above configuration, the membrane having flexibility mitigates a rapid pressure change in the manifold caused by backflow of ink, and thus, cross-talk between adjacent pressure chambers during ink ejection can be effectively prevented.

摘要： An inkjet printing apparatus according to example embodiments may include a flow channel plate including an ink inlet for introducing ink, a pressure chamber containing the introduced ink, and a nozzle connected to the pressure chamber and configured to eject ink. A piezoelectric voltage applier may apply a piezoelectric driving voltage to the piezoelectric actuator in such a way that the volume of the pressure chamber is reduced so as to eject an ink droplet. An electrohydrodynamic voltage applier may apply a first electrohydrodynamic driving voltage and a second electrohydrodynamic driving voltage to the electrohydrodynamic actuator. The first electrohydrodynamic driving voltage may generate a jet from the ink droplet such that the jet is ejected towards a printing medium, and the second electrohydrodynamic driving voltage (which has an opposite polarity to that of the first electrohydrodynamic driving voltage) may restore the ink droplet to the nozzle.
