X=Y addresser for transducer arrays using diagonal diode pairs - connects electrode of each transducer so that row and column conductor is grounded when transducer operates

摘要

The transducer group is laid out in a rectangular grid format with m rows and n columns for convenience in electric addressing. Each transducer has a common electrode and a second electrode which is connected to one row and one column. Upper and lower flexible films carry the m electrode strips for the rows and the n electrode strips for the column. The second electrode of each transducer is connected between two series diodes which are connected between a row and a column. Each row and column is alternately supplied by positive or negative potential at one end and the activation of a transducer brings a row and column to ground potential. The activation is detected at the end of the row or column conductor and the operated transducer defined by row and column position.
