LG Displays OLED EX promises lighter TVs with even thinner frames

LG Display is once again upgrading the OLED technology used in their TVs with the latest breakthrough that helps close the brightness gap between OLED and LCD screens.

The next generation of LG Display’s technology is called OLED EX, and it looks set to be a successor to the company’s latest OLED Evo, which itself has had a brightness upgrade over previous OLED TV models.

In a press release, LG Display explains that “the next generation of OLED EX display implements LG Display’s deuterium and personalized algorithm-based ‘EX Technology’, which helps boost the overall image quality of the innovative display by increasing the brightness by up to 30 percent compared to with conventional OLED screens. “

In addition to these enhancements, the OLED EX retains the key features we expect from the OLED, including “perfect black, rich and accurate color expression as well as an extremely fast response time”, which can be found on LG’s current lineup of OLED TVs.


The most important physical upgrade in these new OLED EX monitors is the use of the deuterium compound instead of hydrogen elements in organic light-emitting elements “to make high-efficiency organic light-emitting diodes that emit stronger light.” That said, LG’s OLED Evo panels also use deuterium, according to MakeUseOf, to achieve a 20% increase in brightness, allowing the LG G1 screen to achieve 728 nits.

LG Display pairs the physical upgrade with thinner frames and a new algorithm that will use machine learning to assess users’ individual display patterns and manage energy input to “accurately express the details and colors of the video content being played.”

Since OLED EX only improves the brightness by 30% compared to “conventional OLED screens”, it is a sure bet that it will be a more marginal increase compared to existing OLED Evo screens. When this is the case, the LG Display is likely to continue to highlight the other eye-catching features of OLED displays, as these OLED EX panels are likely to still lag behind competing LCD TVs, which boast a maximum brightness of over 1,000 nits.

LG Display’s OLED EX technology is possibly more prevalent than OLED Evo, which only appeared in LG’s more premium OLED TV. LG explains that it will use OLED EX technology in all of its OLED TVs manufactured at their Paju and Guangzhou production facilities starting in Q2 2022.
