中文摘要	液晶顯示器是目前最主要的顯示元件，隨著使用量持續攀升使廢棄物的產出量亦是逐年以倍數成長。廢液晶顯示器的結構雖然複雜，其中除了液晶面板外大部分材料皆可回收再利用。針對過去僅能掩埋或焚化處理的液晶面板，行政院環境保護署已與工研院合作開發將液晶面板中的液晶、銦和玻璃分離再利用。鑒於國內在電子廢棄物的資源循環方面成效頗佳，且具備完整的液晶顯示器產業鏈，可串聯國內廢電子電器暨廢資訊物品處理業者、塑膠再生料處理業者和液晶顯示器相關業者，針對市售廢棄液晶顯示器創新開發高值外循環再利用管道。首先取得約7,107公斤市售廢棄面板，串聯廢電子電器暨廢資訊物品處理業者進行拆解處理，萃取出混合液晶6.5公斤，結合液晶分群、調配改質及純化方式將取出液晶調配純化成1.5公斤超高畫質顯示器面板之原料。並透過面板廠將純化調配後液晶製成200片65吋超高畫質液晶面板，完成市售廢棄面板循環再製成高階顯示器用面板之驗證。剩餘的玻璃製成200片高效吸水杯墊。如此不但減少廢料的產生，使資源高值再利用，將液晶等面板材料的循環利用效益最大化，更創造市售廢液晶顯示器之新循環商機。

液晶顯示器是目前最主要的顯示元件，隨著使用量持續攀升使廢棄物的產出量亦是逐年以倍數成長。廢液晶顯示器的結構雖然複雜，其中除了液晶面板外大部分材料皆可回收再利用。針對過去僅能掩埋或焚化處理的液晶面板，行政院環境保護署已與工研院合作開發將液晶面板中的液晶、銦和玻璃分離再利用。鑒於國內在電子廢棄物的資源循環方面成效頗佳，且具備完整的液晶顯示器產業鏈，可串聯國內廢電子電器暨廢資訊物品處理業者、塑膠再生料處理業者和液晶顯示器相關業者，針對市售廢棄液晶顯示器創新開發高值外循環再利用管道。首先取得約7,107公斤市售廢棄面板，串聯廢電子電器暨廢資訊物品處理業者進行拆解處理，萃取出混合液晶6.5公斤，結合液晶分群、調配改質及純化方式將取出液晶調配純化成1.5公斤超高畫質顯示器面板之原料。並透過面板廠將純化調配後液晶製成200片65吋超高畫質液晶面板，完成市售廢棄面板循環再製成高階顯示器用面板之驗證。剩餘的玻璃製成200片高效吸水杯墊。如此不但減少廢料的產生，使資源高值再利用，將液晶等面板材料的循環利用效益最大化，更創造市售廢液晶顯示器之新循環商機。

摘要	The amount of waste LCDs dramatically increases along with their annually increasing usage amount. In LCDs complicated structure, they lack of recycling approaches in the display panel part while other components can be reused. In lieu of landfill and incineration, Environmental Protection Association have collaborated with ITRI on the development of LCDs panel recycling technologies. We have successfully not only separated but also reused the liquid crystal, indium, and glass from waste LCDs. With the distinguished technology and advantages of a completed industry chain in Taiwan, this project aims to create the valorized external recycling system of waste LCDs in association with e waste recycling companies, plastics material regenerators, panel manufacturers and module assemblers. The system can recycle currently commercial display devices, and also maximize their reuse profits. In this project, we recycled the liquid crystal from waste LCDs for 65-inch new high-level LCDs, and furthermore used the waste glass to fabricate highly efficient water-absorbing coasters. We collected 7.1 tons waste LCDs and disassembled them by the e-waste recycling company. The 6.5 kg liquid crystal mixtures were thereafter extracted from those display panels through our developed liquid crystal extraction technology. Combining with group separation, modification, and purification processes enable to produce 1.5 kg source materials for high-level LCDs. As collaborated with the LCD factory, we have successfully produced 200 pieces 65-inch new high-level LCDs from waste materials. On the other part of glass, we also employed our unique nanoporosification technology to generate 200 pieces highly efficient water absorbing coasters. This strategy can provide the recycling routes with economic benefits from waste LCDs to valorized products, not only increasing the profits but aslo decreasing the pollution.
