Abstract
A display driver system having a plurality of series-coupled display drivers which are synchronized by using the same conductor between adjacent display drivers for communicating display data and synchronization control signals. The display driver serially receives display information at a predetermined clock rate. One of the display drivers becomes a master over the remaining display drivers and provides synchronization data for the system. Each display driver selectively outputs either display information or control information at a single output terminal.
