Abstract
Official abstract text for this publication.
A discharging element substrate, comprising a discharging element configured to discharge liquid, a MOS transistor including a drain terminal electrically connected to a first node to which a first voltage is supplied, a gate terminal electrically connected to a second node to which a second voltage is supplied, and a source terminal and a back gate terminal electrically connected to the discharging element, a switch unit arranged in a current path between the discharging element and a ground node, and a unit configured to make a potential difference between the source terminal and the gate terminal lower than the second voltage in a case where the second voltage is not supplied to the second node.
First claim
Opening claim text (preview).
What is claimed is: 1. A discharging element substrate comprising: a discharging element configured to discharge liquid; a MOS transistor including a drain terminal, a gate terminal, a source terminal and a back gate terminal, the drain terminal being electrically connected to a first node to which a first voltage is supplied, the gate terminal being electrically connected to a second node to which a second voltage is supplied, and the source terminal and the back gate terminal…
