As can be expected from TV manufacturers across the board, LG has announced that it will unveil a new 4K UHD TV at CES 2015 in January. What makes this (as yet nameless) model interesting is the fact that it will make use of quantum dot technology. In short, that means brighter, more colorful viewing.
Quantum dots are semiconducting crystals that range in size from 2 to 10 nanometers. The color of light emitted by a quantum dot when it is excited is determined by its size. LG says it is adding a film of quantum dots in front of the LCD backlight in its 4K TV, with the aim of improving picture color reproduction rate and overall brightness.

"Quantum dots provide an amazing super high technology performance enhancement for LCDs through a unique application of quantum physics," explains Dr. Raymond M. Soneira of display calibration firm DisplayMate (not affiliated with LG) in an article on his company's website. "By incorporating them within the backlight, the LCDs then produce highly saturated primary colors that are similar to those produced by OLED displays, plus they also improve the brightness and power efficiency at the same time."
LG says the technology will be used to enhance the capabilities of its In-Plane Switching (IPS) displays. The firm says that that the color reproduction rate (that is, the extent to which natural colors can be accurately reproduced on-screen) in its IPS screens will be increased by more than 30 percent compared with conventional LCD/LED TVs.
LG's 4K UHD TVs will be on display at CES 2015 in Las Vegas from January 6-9.
