Characterising components of liquid crystal displays to facilitate disassembly

Liquid Crystal Display (LCD) technology has evolved and developed over the past decades to replace Cathode Ray Tube (CRT) display technology as the market leader. This is evident, with global market figures for liquid crystal displays surpassing $75 Billion in 2008.Current End-of-Life (EoL) disposal for LCD screens is typically landfill or incineration, this form of disposal restricts the ability to recover potentially reusable materials from waste LCD screens e.g. steel, aluminium, copper etc. Thus to conserve raw materials and to protect the environment it is essential to replace the traditional flow of products from manufacturer to landfill with a recycle and recover approach.While the recycling methods for CRTs are well established, however those of LCDs are as yet in their infancy. However to reduce consumption of natural resources and reduce quantities of waste going to landfill, recycling process must be encouraged and developed.This paper aims to address the challenges facing EoL treatment of LCD units by analysing LCD build types, structures and component material to establish traits which may make EoL treatment less of a challenge. Analysing this data will lay the foundation to developing a balanced recovery system meeting the needs of economic viability and environmental conservation in future work.
