LG Display didn’t have its usual exhibit of flashy, breakthrough new screens at this year’s CES. This resulted in an odd situation where it was actually Panasonic that shared the most details about LG Display’s latest and greatest OLED panel. Even before any official announcement, it was already the centerpiece of 2025 flagships like Panasonic’s Z95B and the LG G5 from LG Electronics (not to be confused with the display division).
But now the company is ready to spill the full details on its new four-layer tandem OLED design. “33 percent brighter than the previous generation and optimized for the AI TV era, it is the industry’s first-ever OLED display to achieve a maximum brightness as high as 4,000 nits,” LG Display wrote in a press release that went out tonight. The AI mention made me roll my eyes a bit, but there’s no doubting that this is a very impressive panel.
Here’s the rundown on what’s so innovative, according to LG Display:
The new panel’s innovation centers on a Primary RGB Tandem structure, which is LG Display’s proprietary technology that uses independent stacks of RGB elements to produce light. It had previously used a three-stack light source, with two layers of blue elements emitting relatively short energy wavelengths alongside red, green, and yellow elements in a single layer.
The Primary RGB Tandem structure applied to the fourth-generation OLED TV panel organizes the light source into four stacks by adding two layers of blue elements and independent layers of red and green elements. It improves maximum brightness by increasing the amount of light produced by each layer compared to the previous structure.

The latest-gen OLED display uses a four-layer structure to maximize brightness — this time without any micro-lens array technology.
Of course, seeing as we’re squarely in the OLED brightness wars, Samsung Display has its own brighter-than-ever QD-OLED screen that’s going into Samsung’s S95F, which was also announced in Las Vegas. But whereas Samsung is going all in on its glare-free display finish, LG is sticking with a more traditional glossy finish — though it uses “ultra-low reflective technology” to lessen any potential distractions.
Energy efficiency has improved again with the fourth-gen LG Display OLED, and the company says that color brightness can reach 2,100 nits, which is a 40 percent improvement compared to the prior version. These peak brightness numbers are what the panel is technically capable of, but that doesn’t necessarily mean that TV makers like Panasonic will necessarily push it that hard in consumer sets.
Either way, OLED keeps getting brighter and more vibrant while still retaining all of its trademark strengths like perfect blacks, fantastic viewing angles, and fast response times for gaming. The best ones don’t come cheap, but they’re worth saving up for. If you’re after more info on the new panel, I recommend these great videos from Caleb Denison at Digital Trends and Vincent Teoh at HDTVTest.
LG Display’s rival, Samsung Display, did have a CES showcase that my colleague Sean Hollister caught during the show, so be sure to give that a watch as well.
