Although the generation of waste flat panel displays in Korea is expected to exceed one million sets in 2016, a comprehensive recycling technology has not yet been developed for effective recovery of valuable materials from the wastes, rendering to outshine the national prestige as a global leader in display industries. The overall aim of this study was to analyze the statistical data of various valuable materials and their ratio after dismantling 40-inch and 42-inch sized waste LCDs. The analysis results showed that plastic portion of the wastes was about 22% and the portion of PCB (Print Circuit Board) part was about 9% by weight whereas panel part was about 34% and leftovers including metals totalled about 35% by weight. Based on the analytical results, a higher value recycling process could be proposed with advanced material separation techniques.
