LG Display has announced fourth-generation OLED panels designed for TVs that are 33% brighter than the previous generation of screens. These panels are “optimized for the AI TV era” and are the industry’s first OLED displays to reach a maximum brightness of 4000 cd/m².”

For some unknown reason, LG Display didn’t talk about the next-generation displays at CES 2025, even though they are the basis for 2025 flagship TVs, including the Panasonic Z95B and LG G5. The main feature of the new panels is the Primary RGB Tandem structure – LG Display’s proprietary technology that uses independent arrays of RGB elements to generate light. Previously, this technology involved a three-layer light source with two layers of blue elements emitting at short wavelengths, as well as red, green and yellow elements on one layer.
In fourth-generation OLED TV panels, the Primary RGB Tandem structure organizes the light source into four layers, adding two layers of blue elements and independent layers of red and green elements. “This allows for higher maximum brightness by increasing the amount of light produced by each layer compared to the previous structure,” LG Display said in a press release.
Samsung, for its part, presented the S95F TV at CES 2025, which used the brightest QD-OLED panel of its own design. At the same time, Samsung continues to rely on a glare-free screen coating, and LG is improving the glossy one, although it uses “ultra-low reflection technology” in its production.
The color brightness of the new LG Display OLED panel is up to 2100 cd/m², which is 40% more than the previous generation screens. But this is again a peak figure, and it is not a fact that manufacturers using these panels will show these figures in practice in products addressed to consumers.
