LG Display has announced its next-gen OLED display technology called OLED EX. The "EX" in the name stands for "Evolution" and "eXperience" as it is an improved version of OLEDs we have seen so far. It is hoping to resolve some of the limitations of traditional OLEDs and make it a better min-LED tech competitor.
The unique thing about OLED displays is that each of the millions of pixels can be turned on or off at an individual level. This allows the display to deliver perfect blacks, rich colors, and accurate color reproduction. However, these panels are not known to be as bright as other competing options. Their brightness level is around 500-600 nits which are way lower than 2000 nits or higher for mini-LED panels. LG claims that OLED EX displays will be about 30% brighter than traditional OLEDs.
LG says it makes use of Deuterium, one of the two stable isotopes of Hydrogen. Its occurrence in nature is not so common as only 1 Deuterium atom is found in about 6,000 ordinary Hydrogen atoms. The company's R&D team has found a way to extract it from water and apply it to LED devices. It says that the stabilized compound of Deuterium makes it possible for the display to be brighter while maintaining high efficiency.
OLED EX technology has allowed the company to reduce bezel thickness by up to 30%. It says thickness has been reduced from 6mm to 4mm for a 65-inch OLED display. LG is yet to share details about when we can expect to see OLED EX TVs in stores but there should be some time before that happens.
