ABSTRACT:
A printhead, particularly a light emitting diode (LED) printhead, which has improved apparatus for distributing signals to individual printing elements, i.e. LEDs, that are used in the printhead. Specifically, this printhead contains a number of print element arrays, typically arrays of light emitting diodes, and a corresponding number of drive circuits all of which are mounted to a common member, this member illustratively being a metallic stiffener plate. Each of the drive circuits is connected to a corresponding one of the print element arrays. All the print element arrays are typically situated in a co-linear orientation transversely along the member with the drive circuits co-linearly arranged along a side of the arrays. In addition, both drive circuits in every pair of adjacent drive circuits are interconnected, through for example spreader boards mounted to said member along the same side of the print element arrays and outward of the drive circuits with wire bonds extending between adjacent spreader boards, such that all the drive circuits in the printhead are interconnected in a daisy-chained fashion.
