ABSTRACT:
In the gas discharge image display of this invention, the peak value of a write pulse supplied to one of two electrodes of each of fluorescent lamps aligned in a matrix form is substantially equal to the peak value of a sustain pulse supplied to that electrode. Therefore, when a row line drive circuit or a column line drive circuit supplies, in a sustain period of a fluorescent lamp to be discharged, a write pulse to another fluorescent lamp aligned in the same row or column of the matrix form, a voltage at the fluorescent lamp to be discharged can be made constant in the sustain period.
