Abstract
An inkjet printing apparatus includes: an airflow stage extending in a first direction; a print head unit disposed above the airflow stage; and an electric field generating unit that moves in the first direction and generates electric field above the airflow stage.
Claims22
An inkjet printing apparatus comprising:
- an airflow stage extending in a first direction;
- a print head unit disposed above the airflow stage;
- an electric field generating unit that moves in the first direction and generates an electric field on the airflow stage;
- and
- a substrate transferring unit that transfers a target substrate in the first direction over the airflow stage, wherein
- the electric field generating unit is configured to generate an electric field on the target substrate in case that the target substrate moves along with the substrate transferring unit,
- the electric field generating unit to apply an electric field to ink after it leaves the print head unit and both before and after the ink lands on the target substrate.

An inkjet printing apparatus comprising:
- an airflow stage extending in a first direction, the airflow stage including:
- a loading part sequentially arranged in the first direction, the loading part in which a target substrate is aligned, and
- a printing part upon which ink is sprayed onto the target substrate;
- a print head unit disposed above the printing part, the print head unit sprays the ink;
- an electric field generating unit disposed on a side of the airflow stage, the electric field generating unit generates an electric field on the target substrate in case that the target substrate moves in the first direction;
- a substrate transferring unit that transfers the target substrate in the first direction over the airflow stage, wherein
- the electric field generating unit is configured to generate an electric field on the target substrate in case that the target substrate moves along with the substrate transferring unit,
- the electric field generating unit to apply an electric field to the ink after it leaves the print head and both before and after the ink lands on the target substrate.
