A triangular waveform generator for applying a scanning waveform to the scan electrodes of a modular display device includes a constant current source and a coupling transformer. A charge storage capacitor is coupled to the secondary of the coupling transformer. A squarewave generator actuates a switch to alternately charge the capacitor in opposite directions resulting in the generation of the triangular waveform. Discharge means is provided to protect the switch from high voltages which could be developed when the generator is turned off.
