ABSTRACT:
A carriage5is provided with an injection head7to discharge an amount of liquid drops according to the supplied driving pulses and a liquid material sensor17to detect the ink amount hit at a filter substrate at each pixel region. A main controller31determines a waveform of the driving pulses capable of discharging the short amount of liquid drops according to a level of a detection signal from the liquid material sensor17and outputs the determined information on the waveform of the driving pulses to driving signal generator32. The driving signal generator32generates driving pulses according to the received information on the waveform and outputs it to the injection head7. The injection head7adjusts an ink amount at the corresponding pixel region to the target amount of liquid material by injecting the short amount of liquid drops to the corresponding pixel region.
