  • Patent number: 4247854
    Abstract: A driving circuit arrangement for a gas-discharge display device operated asynchronously by a blanking signal generated in a processor applies a voltage level to each of the cells of the display device which is below the voltage level required to fire the cells upon the generation of the blanking signal. This arrangement enables the selected cells to fire upon the subsequent removal of the blanking signal. Switching members are operated by the generation of the blanking signal to precharge each of the cells in the display device during the blanking interval in which data transmitted from the processor selects the character to be displayed.
