Today, LG Display is introducing 4th generation OLED TV displays that are not only brighter than those introduced in 2024, but also more energy efficient and less glare. The LG OLED evo M5 was one of Engadget’s favorite announcements at CES 2025, in part because of the LG Display panels it uses.
LG Display’s new 4th generation OLED 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 maximum brightness is not the same as uniform brightness on the same panel, but it’s still a marked improvement when OLED displays can struggle with brightness. Especially when these benefits are combined with better energy efficiency, which LG Display says is “about 20 percent higher” in the 65-inch 4th generation panel.
The changes in the energy efficiency of the new OLED panels are due to improvements in the panel’s “structure and power supply system,” while the brightness improvements are due to LG’s smart approach to the arrangement of LEDs in the panel. The 4th generation OLED utilizes a “Primary RGB Tandem Structure” which consists of 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 is also aiding color reproduction (and presumably purity) with a new film coating that reduces the amount of light reflected off the panel surface, as well as light absorbed and reflected within the panel. The company claims that all of these developments are aimed at creating better “artificial intelligence TVs,” but if that doesn’t convince you, it looks like TVs with the new panels should look better.
The 4th generation OLED panels will appear in “top mass-market” TVs this year, and LG Display says that the “primary RGB Tandem structure” will be gradually introduced in gaming OLED monitors in the future.
