Patent ID: 7123232

Claim:
An active matrix array device, comprising: a substrate; an army of individually addressable matrix cements carried on said substrate; a set of address conductors connected to said array of matrix elements and carried on group including successive address conductors; and an addressing circuit including a multiplexing circuit integrated on said substrate and connected to said set of address conductors, said multiplexing circuit including a plurality of signal bus lines, said multiplexing circuit being arranged to couple sequentially each group of said set of address conductors to said plurality of signal bus lines with each address conductor in a group being coupled to a respective one of said signal bus lines, and a plurality of signal processing circuits integrated on said substrate, each signal processing circuit being connected to a respective bus line, wherein a first signal processing circuit associated with a first address conductor of a first group of address conductors and a second signal processing circuit associated with a last address conductor of a second group of address conductors are adjacent on said substrate.
