One of the biggest TV developments at CES 2025 was a new fourth-generation 'four-stack' OLED panel developed by LG Display, an independent wing of LG that provides the raw display panels for LG Electronics and other TV makers.

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.

Also featuring in Panasonic’s impressive upcoming Z95B, the new panel achieves a peak brightness of 4000 nits – marking a 33 per cent increase over its predecessor – through a redesigned four-layer structure, dubbed the Primary RGB Tandem structure.

LG Display has unveiled its 4th generation OLED TV panel with a major brightness boost along with some interesting claims and bragging rights.

LG has unveiled the next generation of its OLED technology, which it says is brighter and more energy efficient than ever.

LG Display's new 4th-generation OLED panels are 33 percent brighter than previous generations, while also being more power-efficient.

LG Display Co. on Thursday unveiled its new fourth-generation organic light-emitting diode (OLED) panel designed for artificial intelligence (AI) TVs as part of its push to lead the premium screen market.

LG Display has officially announced the fourth generation of its OLED display technology, and it will be available in LG's M5 and G5 OLED TVs in 2025.
