A display panel driver has two driver circuits that drive separate halves of a display panel. Each driver circuit occupies a separate integrated circuit chip. The driver has a screen saving mode in which each driver circuit displays an independent screen saving image that moves in synchronization with a timing signal. The timing signal is generated in one driver circuit and transmitted by a chip-to-chip interface to the other driver circuit. The two screen saving images are thereby coordinated to create what appears to be a single screen saving display.
