Driving circuit and method for an inkjet printhead

A driving circuit for an inkjet printhead comprising a plurality of driving groups, each driving group comprising a plurality of control switches and actuators, the plurality of control switches and actuators being arranged to a plurality of control switch columns and control switch rows, the driving circuit comprising:

• a group of group-driving lines, for choosing the plurality of corresponding driving groups to be driven;
• when a driving group is driven by a corresponding group-driving line, only the control switches of the aforementioned driving group being driven, the other control switches not of the aforementioned driving group are not conducted;
• a group of column-driving lines, for choosing the plurality of corresponding control switch columns to be driven;
• a group of row-driving lines, for choosing the plurality of corresponding control switch rows to be driven;
• when a control switch is chosen together by a corresponding group-driving line, a corresponding column-driving line, and a corresponding row-driving line, the control switch is conducted to drive a corresponding actuator.
