The new OLEDs from LG Display are even brighter and more energy efficient

LG Display today introduces its 4th generation OLED TV displays, which aren’t just brighter than them appeared in 2024but also more energy efficient and less reflective. The LG OLED evo M5 was one of Engadget’s favorite announcements CES 2025partly thanks to the LG display panels used.

LG Display’s new 4th generation OLED TV panel can achieve a maximum brightness of “up to 4,000 nits,” according to the company, which is 33 percent brighter than the previous generation panel. It’s worth noting that maximum brightness isn’t the same as uniform brightness on the same display, but it’s still a notable improvement when OLEDs struggle with brightness. Especially when those gains come with better energy efficiency, which LG Display says is “around 20 percent higher” for a 4th-generation 65-inch panel.

The changes to the new OLED’s efficiency are due to improvements to the panel’s “structure and power system,” while the brightness improvements are due to a clever change in how LG arranges the LEDs in the panel. The 4th generation OLED uses a “Primary RGB Tandem Structure” that stacks independent layers of red and green light elements with two blue layers. Each layer produces more light, helping to improve brightness and “color purity.”

LG Display also boosts color reproduction (and presumably clarity) with a new film coating that reduces the amount of light reflected from the panel’s surface and the light absorbed and reflected inside the panel. The company says all of these developments are designed to create better “AI TVs,” but if that doesn’t put you off, then it sounds like TVs with these new panels just need to look better, too.

The 4th generation OLED panel will appear in “mass-produced” top-end TVs this year, and LG Display says the “primary RGB tandem structure” will also be gradually introduced in gaming OLED monitors in the future.
