CES 2015 has not started yet but LG has just pre-announced a new Ultra HD TV with quantum dot technology. The quantum dots are used to offer a “wider color palette and improved saturation”.

The rumors were true. LG is planning to release a new Ultra HD TV with quantum dots in next year’s line-up, confirms LG in a press release. The TV is based on an IPS LCD panel.

- “Quantum dot’s vibrant and vivid color reproduction capabilities brings LG’s LCD TVs to the next level when it comes to picture quality,” said In-kyu Lee, head of the TV at LG.

Today’s Ultra HD TVs are not capable of reproducing the full color palette of the Ultra HD standard, namely Rec.2020. Instead, the TV and content industry is still relying on the older Rec.709, originally imagined for HD content.

LG says that its quantum dot technology “works by harnessing nano crystals that range in size from 2 to 10 nanometers”. Each dot can emit a different color, improving the color range of the LCD display. LG says that the current model can increase colors by more than 30 percent compared to conventional LCD displays, which suggests that it is not full Rec.2020.

LG further explains that their quantum dot technology contains no cadmium or any other toxic heavy metals. This has been an issue with previous quantum dot implementations.

More details will be released at CES 2015, which starts on January 5, 2015. FlatpanelsHD is in Las Vegas.
