DRIVING IC AND OPTICAL PRINT HEAD

摘要

An optical print head comprising a light-emitting device (22) having n individual electrodes (28), p common electrodes (27) and a plurality of (nxp) light emitting parts (26) selected by these electrodes, and a driving IC (1) having individual electrodes and m group selecting terminals (CD1-CD40), characterized in that one driving IC is provided with a (q) of plurality light emitting elements (22), and the number q is determined by the number p of common electrodes (27), and the number m of the group-selecting terminals (CD).
