Samsung Electronics announced that the quantum dot (QD) sheets used in its QD TVs received certification for compliance with the Restriction of Hazardous Substances (RoHS) directive and has been verified to contain no cadmium by the global certification institute, Société Générale de Surveillance (SGS).

Samsung says that it has actively developed QD materials and technologies, and has secured around 150 patents for the technology.

According to reports from Korea, Samsung Electronics has decided to accelerate the development of its QD-EL display technology. Working together with its affiliate companies, Samsung aims to commercialize QD-EL displays within the next few year.

The reports suggests that Samsung Electronics is working closely with SAIT (Samsung's advanced research institute) and Samsung Display. QD-EL displays are similar to OLED displays, but they use quantum dots as the emitter material. This is the first display technology that uses the QD's electroluminescence, rather than the photoluminescence, used in color conversion for QD-LCDs, QD-powered microLEDs, and QD-OLEDs.
