LG Unveils OLED EX, the Next Generation of Its OLED TV Tech

LG is having a busy CES 2022 and the show hasn't even started. The company already revealed two bizarre OLED concepts and a pair of odd TVs, but today it made its most significant announcement yet by debuting OLED EX, the next generation of its OLED display technology. From a report: OLED EX (the EX stands for Evolution and eXperience, unfortunately) promises to boost maximum brightness, enhance picture quality, and allow for smaller display bezels. The underlying technology -- millions of individual self-lit pixels -- hasn't changed, but the use of an isotope called deuterium combined with algorithmic image processing can increase brightness by up to 30% over conventional OLED displays, LG claims. As boring as that may sound, the science behind it is actually pretty fascinating. LG found a way to extract deuterium, a rather scarce isotope (there is one deuterium atom in 6,000 hydrogen atoms) that's twice as heavy as hydrogen from water, then applied it to its TV's OLED elements. LG says stabilized deuterium compounds let the display emit brighter light while improving efficiency over time. Moving to the second change, LG is using a "personalized" machine learning algorithm that predicts the usage of each light-emitting diode (on up to 8K TVs) based on your viewing habits, then "precisely controls the display's energy input to more accurately express the details and colors of the video content being played."
