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.

LG plans to launch its brightest-ever OLED screen later this year. A new internal structure enables the fourth-gen panel to achieve a maximum brightness of 4,000

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 has officially released more details on its new fourth-generation OLED TV panel technology, which made headlines at CES 2025 with its four-layer design and will be landing in the likes of the LG G5 later this year.

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.
