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.
