Abstract
Multiple independent images are presented on multiple display devices by driving the display devices with a common set of control signals and a multiplexed set of data signals that convey information representing interleaved components of each independent image. In a preferred embodiment, a unique clock signal is provided to each respective display device that is aligned with the interleaved components of the image to be presented by that respective display. The control, data and clock signals may be obtained by multiplexing control and data signals received from display pipeline circuits, or by generating the, signals using a composite circuit that implements the features of two or more multiplexed display pipeline circuits.
