摘要:
A method for driving a liquid droplet ejecting head having plural liquid droplet ejectors that eject liquid droplets from nozzles according to respective voltage changes applied to plural piezoelectric elements electrically connected in a matrix, wherein a switching element being provided with respect to each piezoelectric element and capable of grounding one of a pair of terminals of the piezoelectric element, the method including: inputting, per unit of one column of the piezoelectric elements, a column controlling signal for switching on/off the switching element; inputting, per unit of one row of the piezoelectric elements, a row signal for switching the other of the pair of terminals of the piezoelectric element to a predetermined voltage applied state, a grounded state or an opened state; and ejecting the liquid droplet from the liquid droplet ejector by forming a voltage change between the pair of terminals of the piezoelectric element, is provided.
