Abstract
The present disclosure relates to an ink jetting apparatus and a printing system including the same, the ink jetting apparatus including a liquid droplet generating unit configured to generate liquid droplets and jet the generated liquid droplets, a guide channel unit having a channel to guide the jetted liquid droplets and control evaporation of the liquid droplets, and being configured to protect the liquid droplets from thermal and physical disturbance; and a nozzle unit configured to discharge the liquid droplets that passed through the guide channel unit towards a substrate.
Claims16
An ink jetting apparatus comprising:
- a liquid droplet generating unit configured to generate liquid droplets and jet the generated liquid droplets;
- a guide channel unit having a channel extending from the liquid droplet generating unit towards a nozzle unit in a direction that the liquid droplets are jetted to guide the jetted liquid droplets, said channel having a length long enough to allow evaporation of a solvent from the liquid droplets during a flow of the liquid droplets in the channel to form micro-fine liquid droplets, and being configured to protect the liquid droplets from thermal and physical disturbance;
- and
- the nozzle unit configured to discharge the micro-fine liquid droplets that passed through the guide channel unit towards a substrate,
- wherein the liquid droplet generating unit is formed as an inkjet head configured to discharge the liquid droplets in drop-on-demand method.
