Abstract

The European Union draft Waste Electrical and Electronic Equipment (WEEE) directive calls for the removal and separate treatment of liquid crystal displays (LCD). This aspect of the legislation will potentially have an important impact upon the future 'End of Life' (EoL) processing of much WEEE. Active Disassembly using Smart Materials (ADSM) has been proven to have applicability in self-dismantling, nondestructive and rapid disassembly of small electronic products. This paper investigates the technical feasibility of removing LCD screens from IT communication products using ASDM technology. In this paper an option is suggested to cleanly separate LCD screens from printed circuit boards, utilizing an LCD bracket made from 'shape memory polymer'. The case study products employed are Nokia Japanese J-Phones. Demonstration experiments with initial results are presented, and future developments discussed. SMB glass transformation temperatures (Tg) and time efficiency in disassembly are considered.

使用主动拆卸技术隔离寿命结束的lcd:可行性研究

欧盟废弃电气和电子设备(WEEE)指令草案要求拆除和单独处理液晶显示器(LCD)。这方面的立法可能会对未来报废电子电气设备的处理产生重要影响。基于智能材料的主动拆卸在小型电子产品的自拆解、无损和快速拆卸中具有广泛的应用前景。本文探讨了利用ASDM技术从IT通信产品中去除LCD屏幕的技术可行性。在本文中，建议使用由“形状记忆聚合物”制成的LCD支架，将LCD屏幕与印刷电路板彻底分离。使用的案例研究产品是诺基亚日本j - phone。给出了初步结果的示范实验，并讨论了未来的发展方向。考虑了SMB玻璃的转变温度(Tg)和拆卸时的时间效率。
