Abstract
According to one embodiment, a droplet ejecting apparatus includes a solution holding container having a solution inlet for receiving a solution on a first side and a plurality of solution outlets on a second side, a plurality of droplet ejecting arrays, each droplet ejecting array being respectively connected to one solution outlet in the plurality of solution outlets, and a first nozzle group in each droplet ejecting array fluidly connected to the respective one solution outlet via a pressure chamber structure.
Claims19
A droplet ejecting apparatus, comprising:
- a solution holding container having a solution inlet for receiving a solution on a first side and a plurality of solution outlets on a second side;
- a plurality of droplet ejecting arrays, each droplet ejecting array being respectively connected to one solution outlet in the plurality of solution outlets;
- a pressure chamber structure on the second side has a plurality of pressure chambers each configured to supply a solution to a corresponding nozzle of the first nozzle group;
- a first nozzle group including a plurality of nozzles in each droplet ejecting array fluidly connected to the respective one solution outlet via the pressure chamber structure;
- and
- a plurality of actuators in each droplet ejecting array each configured to cause a pressure change in a corresponding pressure chamber in the plurality of pressure chambers to control an ejection of a droplet of the solution from the corresponding nozzle.
