ABSTRACT:
An inkjet printhead and a method of driving the inkjet printhead include a flow channel substrate having a pressure chamber, and a piezoelectric actuator formed on the flow channel substrate to apply a driving force to the pressure chamber to eject ink. The piezoelectric actuator includes a piezoelectric layer formed on the flow channel substrate to correspond to the pressure chamber, and a plurality of common electrodes and a plurality of driving electrodes alternately arranged in a length direction of the piezoelectric layer.
