Osram announces new conversion technology for backlighting LEDs

Quantum Colors targets latest Ultra-HD TV standards

The new Quantum Colors conversion technology from Osram Opto Semiconductors will set new standards in LED backlighting for TV displays, according to the company.

For many years leading manufacturers of televisions have been demanding an ever broader colour space. The TV standard is once again moving to a larger colour triangle with Ultra HD. Quantum Colors was developed for precisely this standard. Initial customer projects are in progress, and the Osram technology is scheduled for backlighting LEDs for the mass market by the end of 2016.

Quantum Colors is based on a green quantum converter which is combined with red phosphor on a blue chip. The technology was developed in part in the SSL4EU and Hi-Q-LED projects funded by the EU and the German Ministry of Education and Research (BMBF) and does not require any cadmium. 

Osram says that the development results in numerous advantages over quantum dot sheets which have been used up to now for high-quality colour rendering in TV backlighting. Quantum Colors offers superior coverage of the colour space due to a narrow green peak with a full width at half maximum (FWHM) of only 30 nm. Colour space standards such as DCI can be covered 100 percent and REC2020 more than 80 percent. Also Osram says that the technology does not require the system or any other components to be adapted. This simplifies the production processes and the entire system.

Compared with quantum dot sheet solutions, which are based on semiconductor particles measuring only a few nanometers, costs can be halved. "I can give you an example of how much customers can save", said Peter Lenz, product marketing LED at Osram Opto Semiconductors. "For a 55-inch Ultra HD TV with 100 percent DCI coverage the complete cost of the light source can be as low as 55 euros based on our Quantum Colors technology. The cost of just the quantum dot sheets in existing solutions is twice as high."

Osram says another advantage is the constant colour throughout the life of the LED. Quantum dot sheets take on a bluish tinge over time. As far as lifetime is concerned, Quantum Colors LEDs should last at least 30,000 hours; initial tests have produced positive results.
