초록

In Display such as LCD, LED, and AMOLED or semiconductor related industries are required to have static ionizer inorder to produce reliable goods since the ionizer can create balanced ion that is delivered to producing goods to minimize electricaldamages when manufacturing. However, the most general type of ionization is called, “Corona Discharge” that has a slight chances togenerate unequal and unstable amount of each +/- ion to the target object. Then, the ionization performance will drastically decreaseand end up with quality deterioration problem. In this research, our objective to resolve the current issue via applying “CouplingCondenser” on each counter electrodes of Corona discharging type ionizer. The result is that the ion balance was maintained thesatisfied range that is within +/-100V when we changed the duty ratio of the High Voltage of Pulse AC about 40 ∼ 70%. In addition,when levelling the High Voltage of Pulse AC, the ion balance holds the range within +20 ∼ 0V. Even though we have tested the sameexperiment for a year, we have seen the range changes roughly ± 50V.
