LG Display today announces its 4th generation OLED TV display. Not only is it brighter than the one we announced in 2024, it’s also more power efficient and less reflective. The LG OLED evo M5 was one of Engadget’s favorite announcements at CES 2025, thanks to the LG display panel used.
LG Display’s new fourth-generation OLED TV panels have a maximum brightness of “up to 4,000 nits,” which the company says is 33 percent brighter than previous generation panels. Note that maximum brightness is not the same as uniform brightness across the same display panel, but it’s still a notable improvement if OLEDs struggle with brightness. Notably, these improvements are combined with increased energy efficiency, with LG Display saying the 65-inch 4th generation panel is “approximately 20% more energy efficient.”

The new OLED’s efficiency changes are due to enhancements to the panel’s “structure and power system,” while the brightness improvements are related to clever tweaks to how LG places the LEDs within the panel. The 4th generation OLED adopts a “primary RGB tandem structure”, which stacks independent layers of red and green light elements and two blue layers. Each layer produces more light, helping to increase brightness and “color purity”.
LG displays also improve color reproduction (and possibly purity) with a new film coating that reduces the amount of light reflected from the panel’s surface and absorbed and reflected inside the panel. The company says all of these developments are being done to make better “AI TVs,” but if you’re not upset by that, TVs with these new panels will look even better. I think it should be.
Fourth-generation OLED panels are scheduled to be adopted in “top-of-the-line mass-produced” TVs this year, and LG Display says the “primary RGB tandem structure” will be gradually introduced to gaming OLED monitors in the future. states. .
