  • Ink jet printhead with polarity-changing driver for thermal resistors
    Patent number: 9016836
    Abstract: An ink jet printhead device includes a substrate and a plurality of thermal resistors on the substrate. Each thermal resistor includes first and second electrodes and a resistive layer extending therebetween. A polarity-changing driver is coupled to the plurality of thermal resistors and configured to change a driving polarity between the first and second electrodes of each of the plurality of thermal resistors.
    Type: Grant
