Abstract (en)

[origin: EP1215050A1] An optical print head has a light-emitting device 22 having n individual electrodes 28, p common electrodes 27, and a plurality of (n x p) light-emitting parts 26 selected by those individual and common electrodes and a driving IC 1 having individual electrodes and m group-selecting terminals CD1 to CD40. A plurality of (q) light-emitting devices 22 are provided for one driving IC 1, and the number (q) of light-emitting devices 22 is determined by the number (p) of common electrodes 27 provided on each light-emitting device 22 and the number (m) of the group-selecting terminals CD provided on the driving IC 1. <IMAGE>
