Latest Patents

Kwon’s listed patents address printhead construction and ink ejection. “Method of Manufacturing a Bubble-Jet Type Ink-Jet Printhead” describes forming resistive heater elements on a substrate, then adding electrode and insulating layers, barrier walls, and a nozzle plate. The barrier walls group heater elements in pairs and separate the pairs. The method also describes optional additional electrode and insulating layers.

“Bubble-Jet Type Ink-Jet Print Head and Manufacturing Method Thereof” presents a design that integrates an ink manifold and concave ink chamber into a substrate. It also describes a nozzle plate and a round-shaped heater surrounding the nozzle, assembled without a complex bonding process. The patent explains that the heater forms a doughnut-shaped bubble to eject ink, with the aim of reducing ink backflow and satellite droplets that can affect image resolution.
