RoHS and Quantum Dots – The Saga Continues a Decade Later

For over a decade there has been an exemption in place under the Restrictions of Hazardous Substances Directive (RoHS) for cadmium in displays to allow for the use of Cd-containing quantum dots to enhance the viewing experience. There have been many changes over that time, and with new wording recently adopted in 2024, the exemption will continue, in part, through 2027. This presentation will summarize the history of the RoHS Cadmium exemption and explain how new wording will impact current and future display technologies such as QDEF films, QD-OLED, microLED and EL-QLED.
