DISPLAY MANUFACTURING APPARATUS, AND DISPLAY MANUFACTURING METHOD

摘要

A carriage 5 is provided with an injection head 7 to discharge an amount of liquid drops according to the supplied driving pulses and a liquid material sensor 17 to detect the ink amount hit at a filter substrate at each pixel region. A main controller 31 determines 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 sensor 17 and outputs the determined information on the waveform of the driving pulses to driving signal generator 32 . The driving signal generator 32 generates driving pulses according to the received information on the waveform and outputs it to the injection head 7 . The injection head 7 adjusts 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.
