In a plasma display panel 10, orthogonal conducting lines 12 and 14 are provided to generate a matrix of gas discharge cells 16. By sequentially stepping switch 11 and selectively operating drivers 18, the panel can be operated in the raster-scan manner well known to cathode ray tubes. In order to select a gas discharge cell 16 for light-emitting excitation, a voltage, for example, of approximately 180 volts, is applied across the gas discharge gap by turning on driver 18 so as to provide a zero-volt output. If the gas discharge cell is to remain in a dark unexcited state, voltage across the gas discharge gap is limited to 155 volts by providing a +25 volt output level from driver circuit 18.
