LG Display today introduces fourth-generation OLED displays that are not only brighter than they were before. showed itself in 2024but also more energy efficient and less reflective. LG OLED evo M5 was one of Engadget's favorite ads from CES 2025thanks in part to the LG display panels used.
According to the company, LG Display's new fourth-generation OLED panel can reach a maximum brightness of “up to 4,000 nits,” which is 33 percent brighter than the previous generation panel. It's worth noting that maximum brightness is not the same as uniform brightness across the same display panel, but it's still a noticeable improvement where OLED displays have brightness issues. Especially when these benefits are combined with higher energy efficiency, which LG Display says is “about 20 percent higher” on the 4th generation 65-inch panel.
Changes in the efficiency of the new OLED display are due to improvements to the panel's “structure and power system”, while the brightness improvement is due to a smart tweak to how LG places the LEDs on the panel. 4th generation OLED uses a “primary tandem RGB structure” in which independent layers of red and green light elements are combined with two blue layers. Each layer emits more light, which helps improve brightness and “color purity.”
LG Display also improves color reproduction (and presumably clarity) with a new film coating that reduces the amount of light reflected from the surface of the panel, as well as the light absorbed and reflected within the panel. The company says all of these developments are aimed at creating better “AI TVs,” but if you don't care about that, it looks like TVs with these new panels should look better too.
The fourth-generation OLED panel will appear in the “best” mainstream TVs this year, and LG Display says that “RGB primary tandem structure” will gradually make its way into OLED gaming monitors in the future. .
