Abstract
A nozzle plate and printhead allowing for control of a deflection direction of ejected droplets using electro-wetting, and methods of operating and manufacturing the same. The nozzle plate has at least one nozzle for ejecting fluid and includes electrode segments disposed along a circumference of the nozzle, an insulating layer disposed on a surface of each electrode segment so as to contact fluid in the nozzle, the insulating layer divided into at least two insulating layer segments corresponding to the electrode segments, and a wire pattern electrically coupled to the electrode segments.
