Abstract:
A driving circuit for an inkjet printhead, the driving circuit comprising a group of group-driving lines, a group of column-driving lines, and a group of row-driving lines to drive the printhead, and a plurality of driving groups to be driven by the group of group-driving lines; each driving group comprising a plurality of actuators and control switches to be driven by the corresponding column-driving lines and row-driving lines; when a control switch is driven, a corresponding actuator being accordingly driven; wherein the plurality of control switches in different driving groups are driven by the same group of column-driving lines and the same group of row-driving lines, and wherein when a driving group is driven by a corresponding group-driving line, only the control switches of the aforementioned driving group being driven by the corresponding column-driving lines and row-driving lines at the same time are conducted, the other control switches not of the aforementioned driving group are not conducted.
