LG Electronics (LG) is set to unveil a new 4K Ultra HD TV with quantum dot technology as part of its expanded TV line-up at the 2015 International CES, held from January 6 to 9 in Las Vegas.
LG says that its UHD 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 UHD TV and OLED TV offerings.
The quantum dot 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, LG claims.
The manufacturer adds that the colour reproduction rate in its IPS panels is increased with the addition of the quantum dot film by more than 30% compared with conventional LCD/LED TVs.
UHD TVs with quantum dot technology contain no cadmium or any other toxic heavy metals so are less harmful to the environment, LG adds.
LG Electronics Home Entertainment Company senior vice president and head of the TV and monitor division In-kyu Lee said: “Quantum dot’s vibrant and vivid colour reproduction capabilities brings LG’s LCD TVs to the next level when it comes to picture quality. 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.”
