随着液晶显示设备的广泛应用，液晶显示器（LCD）的废弃量逐年增多，为准确掌握当前及未来废弃 LCD 的产生量及其动态变化规律，对台式电脑 LCD、笔记本电脑和液晶电视三大类主要 LCD 产品2014—2020年的销售量及废弃量进行了预测，分别采用灰色模型 GM（1，1）和 Carnegie Mellon 模型进行分析。结果显示，2014—2020年我国台式电脑 LCD、笔记本电脑、液晶电视三大类 LCD 电子产品的淘汰数量巨大，累计将达108915．3万台，其中再使用和循环利用的废旧产品将达70794．9万和16922．1万台，被用户储存的废旧产品为30051．3万台，最终废弃待处理量为51589．1万台。围绕废弃 LCD 的回收处理问题，进一步分析提出，需从回收管理体系建设与产业化技术研发两方面加以应对。

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.
