Abstract: This present invention is to provide a driving circuit and method for an inkjet printhead. The driving circuit includes a group of group-driving lines, a group of column-driving lines and a group of row-driving lines. The printhead includes a plurality of driving groups which are driven by driving signals inputted in sequence via the corresponding group-driving lines. Each driving group includes a plurality of actuator and control switches which are driven by driving signals inputted via the corresponding column-driving line and row-driving line. Each control switch is just driven when the corresponding group-driving line, column-driving line and row-driving line input driving signals at the same time. Then, the driven control switch conducts the electric current to the corresponding actuator so as to jet out the ink in the ink chamber.
