It was a big year for television at the 2015 CES, with buzzwords such as 4K, HDR, OLED, contrast, color space and curved screens filling the air in Las Vegas. Another hot topic was quantum dots — tiny crystals designed to enhance color and efficiency. Manufacturers including Samsung, LG and TCL are following Sony’s lead in introducing the technology.“Quantum dots promise to solve a very fundamental problem with modern LCD TVs, which is that the range of colors on LED-backlit sets are simply not as good as the ones on plasma and OLED TVs,” reports The Verge. “The allure of quantum dots is that they can be added as a layer on top of an LCD TV’s LED backlight to fine tune the light that makes it through. That can dramatically improve the color gamut, and do it at about a third of the cost of producing OLED displays.”
