Abstract:
1. A fluid ejector, comprising: a fluid ejection module comprising a substrate having a plurality of fluid paths, a plurality of actuators, and a plurality of conductive traces, each actuator configured to cause a fluid to be ejected from a nozzle of an associated fluid path; an integrated circuit element, wherein the integrated circuit element is mounted on the substrate and is electrically connected with the conductive traces of the fluid ejection module such that an electrical connection of the fluid ejection module enables a signal sent to the fluid ejection module to be transmitted to the integrated circuit element, processed on the integrated circuit element, and output to the fluid ejection module to drive each of the actuators; and a flexible element in electrical connection with the fluid ejection module such that the signal sent to the fluid ejection module is transmitted from the flexible element, wherein: the fluid ejection module comprises a plurality of input traces and a plurality of first input pads, wherein the input traces are electrically connected to the flexible element, and wherein the first input pads are electrically connected respectively to the actuators; the integrated circuit element comprises a plurality of integrated switching elements, a plurality of second input pads connected respectively to the input traces of the fluid ejection module, and a plurality of output pads connected respectively to the first input pads of the fluid ejection module, wherein the integrated switching elements are connected respectively to the second input pads and the output pads; and the number of input traces is smaller than the number of output pads.
