EU extends the validity of exemption provisions of RoHS 2 directive
On October 31, 2017, the European Union promulgated a new law in the Official Journal to amend Directive 2011/65/EU, commonly known as the RoHS 2 Directive. The RoHS 2 Directive restricts businesses from using certain hazardous substances, including cadmium, in electrical and electronic equipment. The newly promulgated "European Commission Authorization Directive No. 2017/1975" amends Annex III of the "RoHS 2 Directive". The annex lists various exemptions for banned hazardous substances. This revision involves the exemptions available for the use of cadmium in color-changing light-emitting diodes (LEDs) of current display devices. The directive pointed out that item 39 of Annex III of the RoHS 2 Directive stipulates that the use of cadmium in color-changing LEDs in light-emitting and display equipment is exempted until July 1, 2014. The European Commission received an application to extend the exemption period before January 1, 2013. According to Article 5 of the RoHS 2 Directive, the European Commission may add or extend exemptions in certain circumstances, including when there are doubts about the reliability of alternatives to restricted substances, or when the alternatives have environmental, human health and safety concerns. The benefits cannot make up for the overall adverse effects in these three areas. The directive points out that color-changing LEDs using quantum dots have proven to be superior to previous technologies in terms of energy saving and color performance. Compared with other existing alternative technologies, using cadmium-containing quantum dots in display devices consumes less energy, so the overall benefits outweigh the disadvantages. At the same time, if the display device using quantum dots is changed to
