ABSTRACT:
An AC-powered display system includes a gas discharge display panel, an integrated circuit, and a limiting network. The integrated circuit is provided as the display pattern controller. The limiting network, in response to an excessive voltage across the controller, reduces the current through the system. The reduction in system current causes the voltage across the integrated circuit to be regulated.
