Flat panel display devices are mainly used as information display devices in the 21st century. The worldwidewaste flat panel displays are expected at 2-3 million units but most of them are land-filled for want of a properrecycling technology More specifically, rare earth metals of La and Eu are used as fluorescent materials of Cold CathodeFlourscent Lamp(CCFL)s in the waste flat panel displays and they are critically vulnerable and irreplaceable strategicmineral resources. At present, most of the waste CCFLs are disposed of by land-filling and incineration and properrecovery of 80-plus tons per annum of the rare earth fluorescent materials will significantly contribute to steady supplyof them. A dearth of Korean domestic research results on recovery and recycling of rare earth elements in the CCFLsprompts to initiate this status report on overseas research trends and noteworthy research results in related fields.
