LG Display has revealed some significant improvements to its OLED screen technologies in the run-up to CES 2022. Its latest OLED screen technology is dubbed OLED EX, and it will feature in all new OLED TVs starting in Q2. Key attractions of OLED EX are its "extremely fast" response times and delivery of imagery that is up to 30% brighter in panels with 30% thinner bezels (based on a 65-inch reference model).

With the worthy advances outlined by LG, and the confidence it is showing by adapting its full OLED TV roster, we hope it will proliferate the new OLED EX technology throughout its product stack. That would include monitors, laptop and tablet screens, smartphones and wearable displays. LG's initial PR salvo doesn't quantify the headlining "extremely fast" response times, but it must stir some feelings of desire among PC and VR gaming aficionados.

LG has provided some interesting background on the development of OLED EX, a marketing abbreviation of OLED Evolution eXperience. One of the significant changes under the screen surface is the implementation of deuterium compounds. The company refined the process of efficiently extracting deuterium from water, stabilizing it, and applying it to organic light-emitting devices. Naturally, hydrogen isotope deuterium is rare, so LG's extraction process is important to product affordability. The value of deuterium in the OLED display-making process is that it provides the big max brightness boost noted in the intro, and is said to also be more power-efficient.
