Samsung has developed QLED with a service life of 1 million hours

Samsung Electronics has developed a new method of manufacturing LEDs on quantum points (QLED), which increases their efficiency and extends a deadline for up to 1 million hours.

LEDs on quantum points are excellent for large-pasted displays due to their high efficiency, color purity, reliability and manufacturing efficiency. However, in previous QLED versions, a cadmium harmful to humans was used, and they were not stable enough.

The recently research unit of the South Korean giant improved the structure of quantum dots made from an environmentally friendly phosphide of India. The new version has a homogeneous kernel with an etched oxidative surface and is covered with a symmetric thick shell that prevents the leakage of energy.

According to the developers, it raised the quantum efficacy of QD LEDs by 21.4%, and their service life up to a million hours. Despite the fact that Samsung already has 170 patents on the elementary QLED structure, it will continue to work in this direction, since technology still has some problems.

The company does not call an approximate date of the framework of the serial production of QLED-displays, and in the coming years they should not be expected.
