While LG Display’s production of new so-called EX OLED panels in 2022 undoubtedly had a transformative effect on the picture quality of many of the year’s premium OLED TVs, the roll out of this brightness and colour-enhancing technology wasn’t without its issues. Early limitations with producing small EX OLED screen sizes meant that some early production runs of premium 2022 OLED TV series had to make do with older OLED panels in their smallest screen sizes. Also, cheap OLED ranges typically had to be built around non-EX OLED tech, denying them the potential 30% brightness enhancement, extra colour volume/naturalism and slimmer designs EX panels are capable of delivering.

Happily, though, it looks like we can look forward to a much wider and more consistent EX presence in the OLED world going forward thanks to LG successfully converting two of its most important OLED production facilities to 100% EX panel production. This means in effect that every OLED panel LG Display makes from now on will use EX technology.

According to LG Display (as initially reported by Flatpanels HD), its massive plants in Paju, South Korea and Guangzhou, China have been producing exclusively EX panels since the end of the second quarter of 2022 – early enough to fit in with the design and production schedules of all the main TV brands’ 2023 TV ranges.


This doesn’t necessarily mean that EVERY OLED TV in 2023 will benefit from an EX panel; potentially large stockpiles of older panel designs could still find their way into ‘budget’ OLED ranges.

EX panels introduce deuterium to the manufacturing process – a material that’s more resistant to electrical stimulation and heat than traditional OLED manufacturing materials, enabling the panels to run more brightly without risk of the organic elements being ‘worn out’ faster. The EX manufacturing process also enables OLED panels to be be 4mm slimmer than their regular OLED counterparts, leading to a new generation of thinner and also much lighter OLED TV designs.

LG Display has also been talking more about another claimed benefit of EX technology whereby all EX panels that come off the production line are checked over by an AI-backed monitoring system to assess their specific capabilities and optimise the way their pixels work accordingly. A process which results, says LG, in “the truest, most natural colours on screen.”

There’s also a chance, of course, that LG Display being able to ramp up EX panel production so significantly over the course of 2022 might create economies of scale that could lead to cheaper high quality OLED TVs next year. Though the spiralling costs of energy, production and shipping impacting global markets at the moment may mean we have to wait a little longer before any really significant pricing benefits show through.
