APPARATUS AND METHOD FOR EJECTING LIQUID DROPLET, HEAD DEVICE FOR EJECTING LIQUID DROPLET, METHOD FOR MANUFACTURING DEVICE, AND DEVICE CAPABLE OF REDUCING DATA RATE FROM PRINT CONTROLLER TO LIQUID DROPLET EJECTING HEAD

摘要

PURPOSE: An apparatus and a method for ejecting liquid droplet, a head device for ejecting liquid droplet, a method for manufacturing a device having a process ejecting liquid droplet, and the device are provided to reduce a data rate transmitted from a print controller to a liquid droplet ejecting head and to manufacture various devices without reducing a manufacturing efficiency. CONSTITUTION: An apparatus for ejecting liquid droplet includes a liquid droplet ejecting head device having a liquid droplet ejecting head(28) for ejecting a liquid droplet. A controlling device(11) transmits recording data for determining whether or not the liquid droplet is ejected and transmits a driving waveform for driving the liquid droplet ejecting head(28) to the liquid droplet ejecting head device. The liquid droplet ejecting head device includes a memory unit for memorizing a part or all the recording data. The liquid droplet ejecting head device controls the liquid droplet ejecting head, which ejects the liquid droplet on the base of the driving waveform transmitted from the controlling device and the recording data memorized at the memorizing unit.
