SYSTEM FOR DISPLAYING INFORMATION IN ALPHANUMERIC FORM |
摘要 |
Information is displayed in alphanumeric form on a screen of a gas discharge tube having row and column electrodes with intersections. Gas in the tube is ionized in response to a predetermined ionizing voltage existing between the rows and columns at selected intersections to cause a visible signal to be derived at the intersections. Logic means applies ionizing voltages to column electrodes of the screen in a sequential scan. A video scan controller has one input responsive to signals representing coded characters to be displayed column by successive column. A character generator responsive to signals derived from the scan controller activates a controlled logic circuit so ionizing voltages are applied to predetermined row electrodes in the screen to activate the selected intersections to display the coded characters. |
