LG Display today introduces its 4th generation OLED TV screens, which not only manage to be brighter than what they presented in 2024, but also more energy efficient and less reflective. The LG OLED evo M5 was one of Engadget’s favorite announcements at CES 2025, thanks in part to the LG Display panels it uses.
LG Display’s new 4th generation OLED TV panel can achieve peak brightness “up to 4,000 nits,” according to the company, which is 33% brighter than the previous generation panel. It’s worth noting that peak brightness isn’t the same as uniform brightness on the same display panel, but it’s still a notable improvement when OLEDs can struggle with brightness. Especially when these gains are coupled with better power efficiency, which LG Display says is “around 20% better” on a 65-inch 4th generation panel.
Changes to the efficiency of the new OLED are due to improvements to the panel’s “structure and power system”, while improvements in brightness are linked to a clever change in the way 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, which helps improve brightness and “color purity.”
LG Display also improves color reproduction (and likely purity) with a new film coating that reduces the amount of light reflected from the panel surface and the light absorbed and reflected inside the panel. The company says all of these developments are aimed at creating better “AI TVs,” but if that doesn’t sway you, it looks like TVs with these new panels should look better, too.
The 4th generation OLED panel will appear on “mass-produced high-end” TVs this year, and LG Display says the “primary RGB tandem structure” will also be gradually introduced into gaming OLED monitors in the future. .
