Abstract
As the popularity of liquid crystal display (LCD), the number of end-of-life (EOL) LCD panel is increasing sharply. In this case, how to recycle the resources that it contains and reduce the negative impact on the environment that it will produce has been a great challenge. This research, which was based on analysis of the structure features and material properties of LCD panel, divided the recycling process for EOL LCD panel into four parts, including the separation of two glass substrates, the extraction of liquid crystal, the separation of multi-layers film and polarizing film from glass substrate. Experiments were carried out based on the theoretical analysis so as to find out a desirable resolution to each part. Finally, the optimal and practical synthetic recycling process had been obtained so as to make sure that liquid crystal, indium resources, glass substrates and polarizer could be separated and sorted for recycling more effectively and help to promote the industrialization of recycling of EOL liquid crystal display panel.
