OLED TVs with brightness up to 4,000 nits.

LG's fourth-generation panel, capable of reaching 4,000 nits of brightness, has already appeared in some of the most anticipated TV models of 2025, including the LG G5 and Panasonic Z95B.

LG didn't have a spectacular presentation like in previous years at CES 2024. This led to a rather strange situation where it was Panasonic that revealed the most information about LG Display's new and most advanced OLED panel.

It wasn't until January 16th that the South Korean brand revealed full details about its fourth-generation OLED panel. "33% brighter than the previous generation and optimized for the AI ​​TV era, this is the industry's first OLED display to achieve a maximum brightness of up to 4,000 nits," LG stated in a press release.

According to LG Display, the breakthrough of this panel lies in its Primary RGB Tandem structure, a proprietary technology that uses independent RGB layers to create light. Previously, LG Display used a 3-layer structure with two blue layers emitting shorter wavelengths along with red, green, and yellow layers combined in a single layer.

Meanwhile, with the Primary RGB Tandem structure in 4th generation OLED TV panels, the light source is organized into four layers by adding two blue layers and separate red and green layers. This enhances maximum brightness by creating more light in each layer compared to the old structure.

In addition to brightness, the energy efficiency of the 4th generation OLED panel has also been improved. LG Display says the color brightness reaches 2,100 nits, 40% higher than the previous version.

Although these figures represent the maximum potential of the panel, it's not certain that TV manufacturers like Panasonic will fully utilize it in their commercial products.

In the race for OLED TV panels, Samsung Display is also not to be outdone, announcing the brightest QD-OLED panel ever, featured in the Samsung S95F TV model recently launched in Las Vegas.

Accordingly, Samsung focuses on optimal anti-glare screen technology, while LG retains the traditional glossy coating but uses ultra-low reflectivity technology to minimize image noise.
