Abstract: With wide use of liquid crystal displays (LCDs), the amount of waste LCDs is increasing each year. To accurately grasp the amount of waste LCDs and its trend in the following years, the sales and discarded amount of desktop LCDs, notebooks and LCD TVs were respectively predicted by Gray Model (1, 1) and Carnegie Mellon model. The results show that the accumulated obsoleted amount of desktop LCDs, notebooks and LCD TVs in 2014-2020 will be 1 089.15 million units, and the amount for reuse and recycling will be 707.95 and 169.22 million units, respectively. The amount for storage will be 300.51 million units and the final discarded amount will be 515.89 million units. To solve the problems of waste LCDs recovery and treatment, it is imperative to establish more efficient recovery management system and future develop industrialization technologies.
