Abstract: A bluge rotational tool has been developed as an effective precision electrochemical removal for the thin film nanostructures from LCD panels. This ultra-precise process effectively removes defective Indium-Tin-Oxide layers allowing LCD panels to be returned to the production line and significantly reduces costs. In the current experiment a 7th Generation TFT-LCD panel was used. A high rotational speed of the cheek rotational tool elevates discharge mobility and improves the removal effect. A negative electrode of large diameter with a small end radius provides higher current density and also improves the removal affect. Pulsed direct current can improve the effect of dregs discharge and is advantageous when combined with a higher electric power. A fast feed combined with a high current flow results in very effective removal of the color filter layer. This novel design using electrochemical removal as a precision recycling process for removing ITO layers from LCD panels is clean, effective and very fast.
