LCDs have replaced CRTs as the main display devices recently. Tosatisfy the increasing demands, billions of LCDs are manufactured annually. However, as more LCDs are produced and used, the amount of LCD waste is increasing at an alarming rate. LCD waste can be simply disassembled into a numerous parts, most of which are commonly recycled, but the LCD panels typically are not. Waste LCD panels are generally disposed of in a landfill or by incineration. An increasing number of countries are prohibiting such treatments, because waste LCD panels are potentially hazardous and detrimentally affect health. It is important to create a viable LCD disposal solution. In order to avert a growing environmental problem which was caused by discarding LCD panels, a method that offers an efficient way to separate liquid crystal from waste LCD panel was developed. However, the recyclability of the liquid crystal needed further confirmation. In this study, the liquid crystal which is collected from waste LCD panel, after it had undergone extraction, purification and blending, was utilized to produce 100 pieces of LCD panel. The product yield, and the display performance and reliability of the panels were used to evaluate the feasibility of the method.
