Abstract
A reuse fabrication module that uses micro electroremoving as a precision machining process with a new design of the cam-form tool to remove defective indium-tin-oxide (ITO) thin film from the optical PET surfaces of a digital paper display is presented. A small diameter of the cathode of the cam-form tool corresponds to a higher removal rate for the ITO nanostructure. A small edge radius of the anode and a small gap width between the cathode and the ITO surface takes less time for the same amount of ITO removal. A higher feed rate of the optical PET diaphragm combines with enough electric power to drive fast micro-electroremoving. The high rotational speed of the cam-form tool can improve the effect of dreg discharge and is advantageous to associate with the fast feed rate of the optical PET diaphragm.
