Abstract: The present invention uses temporary storage of data sub-frames to obviate the need for a multiplicity of driver circuit packages and eliminate the traditional one-to-one association of driver circuit channels with selected data electrodes in the addressing of a flat panel display matrix. Display data signals are serially induced along a controlled velocity signal propagation transmission line to create signal profiles representative of data sub-frames, a data frame being the amount of data required to address a single display row. Individual informational "bits" of the data sub-frame are captured, in timed sequence or in parallel, from the signal profile by the multiplexer assemblies tapped into the transmission line at particular sites along its length. When the assemblies are enabled, the signal profile along the transmission line is exposed to a charge storage capability. The informational bits of the signal profile representing the sub-frame are, consequently, captured.
