<p>A driving circuit for an FED capable of re-using charge accumulated in gate lines, cathode lines or anode lines, so that the swing width of the drive voltage for the FED resulting from a supply voltage is reduced, thereby achieving a reduction in power consumption while improving the reliability of high-voltage devices. The driving circuit includes output circuits (28, 30) connected to lines, which are gate, anode, or cathode lines, and adapted to charge the lines in a sequential method based on successive line selection control signals, respectively, switching devices each coupled between adjacent ones of the lines and adapted to conduct a switching operation based on a switching control signal, logic operating devices each adapted to receive an associated one of the line selection control signals while receiving a charge recycling signal, thereby controlling a charge migration from a currently activated one of the lines to the line adapted to be activated following the currently activated line, and switching controllers each coupled to an associated logic operating device while being coupled to controller serving to control the switching operation of the associated switching device based on an output signal from the associated logic operating device.</p> |
