LG Display is introducing its fourth generation of OLED TV panels today, which are not only brighter than what it offered in 2024, but are also more energy efficient and less reflective. The LG OLED evo M5 was one of Engadget’s favorite ads from CES 2025, thanks in part to the LG Display panels it uses.
LG Display’s new fourth-generation OLED TV panel can reach 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 the maximum brightness isn’t the same as the uniform brightness across the display panel itself, but it’s still a noticeable improvement when faced with brighter OLED displays. Especially when these gains are coupled with better power efficiency, which LG Display says is “about 20 percent greater” on the 65-inch 4G display.
The new OLED’s efficiency changes are due to improvements to the panel’s “power and energy supply system structure,” while the brightness improvements have to do with a clever tweak to how LG arranges the panel’s LEDs. The fourth generation of OLED uses a “basic RGB Tandem Architecture” that combines independent layers of red and green light elements with two blue layers. Each layer produces more light which helps improve brightness and ‘purity of color’.
The LG display also helps with color reproduction (and supposed purity) with a new coating that reduces the amount of light reflected from the panel’s surface and light absorbed and reflected within the panel. The company says all of these advances are in the service of making better “AI TVs,” but if that doesn’t sway you, it looks like TVs with these new panels should look better, too.
The fourth-generation OLED panel will appear in “fantastic, mass-produced” TVs this year, and LG Display says the “RGB Tandem infrastructure” will be gradually introduced into Gaming OLED displays in the future as well. .
