Abstract

The present invention is directed to a drive system adaptable to a matrix scanning device. A number of first drive circuits are disposed on a first periphery along a first direction of a substrate with each said first drive circuit being coupled to at least one column wire of the matrix scanning device. A number of second drive circuits are disposed on a second periphery along a second direction of the substrate with each said second drive circuit being coupled to at least one row wire of the matrix scanning device. A master controller controls the first drive circuits and the second drive circuits. A bus is electrically coupled to the master controller, the first drive circuits and the second drive circuits.
