A circuit arrangement rapidly triggering a light-emitting and control bistable circuit into stable ON and OFF states while operating potential is continuously applied to the selective circuit to provide light emitting and de-energized states. A light-emitting element or an element added in series therewith acts as a capacitor. The light-emitting and capacitive elements are connected in series with a threshold switching device having inherent time delay characteristics, and connected at the circuit juncture between the light-emitting and capacitive elements and the threshold switching device is a start and stop circuit preferably with isolation means for selectively applying start and stop pulses to charge the capacitor while bypassing the threshold switching device to initiate operation of the circuit during one instance, and to discharge the energy stored in the capacitive element to terminate operation of the circuit during another instance. A display array of rows and columns of such bistable circuits is formed with means for energizing selectively desired start and stop circuits associated with selective bistable circuits independently of the threshold switching devices used in the circuits and for providing means, independent of the operating potential lines, for addressing selected ones of the electroluminescent circuits within an array.
