Abstract
An inkjet head includes an ink chamber, a pressure chamber and a piezoelectric member. The ink chamber includes an ink storage area storing ink, a plurality of dampers filled with the ink to be discharged, and a plurality of nozzles connected to the dampers and discharging the ink. The pressure chamber is disposed on the ink chamber, overlapping at least two of the plurality of dampers, and includes a pressure transmitting medium. The piezoelectric member is disposed on the pressure chamber. The ink is discharged from the nozzles in substantially a same amount through control of a single piezoelectric member at one time.
Claims16
An inkjet head comprising:
- an ink chamber including:
- an ink storage area storing ink,
- a plurality of a damper filled with the ink which is discharged from the dampers, and
- a plurality of a nozzle fluidly connected to the dampers, and through which the ink is discharged from the inkjet head;
- a pressure chamber disposed on the ink chamber, overlapping at least two of the plurality of the damper, and including a pressure transmitting medium;
- and
- a piezoelectric member disposed on the pressure chamber,
- wherein the ink is discharged from the nozzles of the at least two of the dampers in substantially a same amount, when the piezoelectric member is actuated a single time.
A method of forming a thin film pattern of a liquid crystal display, the method comprising:
- applying a pressure in an inkjet head;
- discharging a substantially same amount of an ink from a plurality of a nozzle of the inkjet head;
- and
- depositing the ink in the thin film pattern of the liquid crystal display,
- wherein the inkjet head comprises:
- an ink chamber including:
- an ink storage area storing the ink to be deposited, and
- a plurality of a damper filled with the ink and fluidly connected to the nozzles;
- a pressure chamber disposed on the ink chamber, overlapping the plurality of the damper, and including a pressure transmitting medium;
- and
- a piezoelectric member disposed on the pressure chamber,
- wherein the ink is discharged from the nozzles of the inkjet head in the substantially same amount, by a single actuation of the piezoelectric member effecting the pressure to the ink chamber.
