Abstract
An alphanumeric display system which may be implemented on one or more semiconductor chips for controlling display devices arrayed in N groups, each group of which comprises an A by B matrix of devices and which is capable of displaying a single alphanumeric character. The display devices in each group are sequentially addressed with display commands being communicated therewith in a predetermined manner to cause the display devices to visually display a predetermined alphanumeric character. Use of the alphanumeric display system herein disclosed, permits a total of A by B by N display devices to be controlled by the display system using as few as A + B + N connecting conductors to control the display devices and associated display driver devices.
