Quantum dot tech for LG UHD TVs

December 16, 2014

LG Electronics will unveil a new 4K Ultra HD TV with quantum dot technology as part of its expanded TV line-up at the 2015 International CES in Las Vegas.

LG’s 4K Ultra HD TVs with quantum dot technology will offer a wider colour palette and improved colour saturation than conventional LCD TVs and will be available in 2015 to complement LG’s other Ultra HD TV and OLED TV offerings.

LG’s quantum dot technology displays an extremely wide colour gamut, making it ideal for 4K content. The technology works by harnessing nano crystals that range in size from two to 10 nanometres. Each dot emits a different colour depending on its size. By adding a film of quantum dots in front of the LCD backlight, picture colour reproduction rate and overall brightness are significantly improved. Since the nano-sized dots emit extraordinarily vivid colours, quantum dot technology is able to enhance the already stunning capabilities of LG’s 4K Ultra HD In-Plane Switching (IPS) displays. The colour reproduction rate in LG’s IPS panels, which offers high colour accuracy and extra-wide viewing angles, is increased with the addition of the quantum dot film by more than 30 percent compared with conventional LCD/LED TVs.

“Quantum dot’s vibrant and vivid colour reproduction capabilities brings LG’s LCD TVs to the next level when it comes to picture quality,” said In-kyu Lee, senior vice president and head of the TV and monitor division at the LG Electronics Home Entertainment Company. “The addition of Ultra HD TV with quantum dot technology to our TV line-up positioned under our award-winning OLED TVs further establishes LG as a leading provider of the most diverse and innovative TV display technologies in the industry.”
