LG to Unveil Quantum Dot-Powered Ultra HD TV at CES 2015

By Chris Boylan

Today I'm here to talk to you about quantum dots and nano technology. No, I'm not referring to a new "Star Trek" series or Elon Musk's latest brainchild. I'm talking about televisions. Just when you thought LED/LCD TV was a mature technology, along comes something to challenge that belief. LG Electronics announced today that it will show a 4K Ultra HD LCD TV at CES 2015 powered by quantum dot technology.

Quantum dots replace the traditional RGB filter layer in an LED/LCD TV allowing these TVs to be brighter, with a wider color gamut for richer, more vivid colors. Quantum dots used in the LG TV vary in shape and size from about 2 nanometers to 10 nanometers in diameter. Depending on the size and shape of the dot, each one acts as a different color filter. These dots are arranged in a precise array to filter a pure blue LED light source in order to reproduce a wide spectrum of colors.

LCD TVs powered by quantum dot technology will be part of LG's Ultra HD TV lineup for 2015. The quantum dot TV's will use LG's IPS (In Plane Switching) panel for improved off-axis viewing compared to traditional LCD panels. These new TVs will also include an improved Smart TV Interface powered by WebOS, which the company acquired from HP in 2013.

In a briefing earlier this month, LG's Tim Alessi told Big Picture Big Sound that the more dynamic image and wider color spectrum make the quantum dot technology a perfect fit for the higher resolution and greater detail of 4K Ultra HD TV. "It's one of the ways we're working on improving the performance of LCD TV in 2015 and beyond, but it's not the only way..."

Quantum dot Ultra HD TV will join other LED/LCD TV technologies as well as OLED TVs in LG's 2015 television line-up.

More announcements will follow as CES approaches so stay tuned.
