METHOD FOR DRIVING LIQUID DISCHARGE HEAD, LIQUID DISCHARGE HEAD, AND LIQUID DISCHARGE APPARATUS |
摘要 |
<p>A liquid discharge apparatus includes: a liquid discharge head which includes; a discharge port to discharge a liquid; and a substrate including: an energy generating element for generating thermal energy to discharge the liquid from the liquid discharge port; a pair of electrodes connected to the energy generating element for driving thereof; an insulating layer of an insulating material provided to cover the energy generating element; and a metal layer of a metal material provided corresponding to the energy generating element to cover the insulating layer; and a driver unit which sets a first potential of one of the pair of electrodes substantially equal to the potential of the liquid and a second potential of the other one of the pair of electrodes lower than the first potential to drive the energy generating element.</p> |
