1. A display driving device for a display, comprising:

  • an optical wave guide plate which introduces light to said display;

    a drive section disposed opposite one face of said optical wave guide plate, said drive section including a plurality of actuators arranged corresponding to a plurality of pixels which in turn correspond to a plurality of dots, said drive section controlling a displacement of said plurality of actuators in contacting and separating directions with respect to said optical wave guide plate, said displacement corresponding to attributes of an input image signal, thereby causing an image to be displayed on said optical wave guide plate corresponding to said image signal by controlling a leakage light from specified parts of said optical wave guide plate;

    a first drive circuit which applies an offset potential to all of said actuators;

    a second drive circuit which outputs a data signal for each dot, said data signal being based on said image signal, said data signal comprising one of a light emitting signal and a light extinguishing signal; and

    a signal processing circuit which controls said first and second drive circuits wherein one dot is configured by one or more actuators and one pixel is configured by one or more dots, and wherein said second drive circuit controls gradation by at least a temporal modulation method.
