Abstract (en)

A plurality of light emitting diodes (60) each diode including an anode (64) and a cathode (63), and divide into rows and columns. Rows and columns of conductors (62, 65) positioned to correspond, one each, with the rows and columns of diodes, and alternate columns of anodes and cathodes being reversed. Each row conductor has alternate cathodes and anodes connected thereto, and each column conductor with anodes connected thereto is connected to a column conductor with cathodes connected thereto so as to reduce the number of inputs by one half. A specific column of each pair is addressed by applying a positive or negative signal (b0) to each input. <IMAGE>
