Inkjet printing apparatus and method of driving inkjet printing apparatus |
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.
