Abstract

Apparatus addressing multi-position display devices directly from semiconductor integrated circuits and driving the display electrodes via passive coupling without exceeding the limitation on voltage excursions for the outputs of such circuits. The apparatus develops and applied to threshold-responsive display devices, including gas discharge display tubes or panels, only the amount of bias that is needed for operation of the device by the signal potentials that are available. Bias potential for the display electrodes is accumulated in steps until the device fires, and then is automatically adjusted each cycle in relation to the number of display electrodes that are being operated.
