ABSTRACT:
In a light emitting diode print head of the dynamic drive method type including an upper substrate having a transversely elongated opening, a plurality of common electrodes arranged on the first side region of the opening of the upper substrate in parallel therewith, a plurality of light emitting diode array chips each mounted on one of the common electrodes, a plurality of drive circuits arranged on the second side region of the opening of the upper substrate, a plurality of drive ICs mounted on the upper substrate between the opening and the drive circuits, the number of the drive ICs being the same as that of the array chips, a lower substrate divided into a plurality of wiring regions and having the same size as that of the upper substrate, the number of the wiring regions being the same as that of the drive ICs, and a plurality of individual electrode wirings of undulated form arranged on the wiring regions along the length of the lower substrate and corresponding to the electrode pads of the light emitting diode array chips, wherein the upper substrate is mounted on the lower substrate.
