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.

We were thoroughly impressed with the LG G5's predecessor, the LG G4, which earned five out of five stars in our LG G4 review thanks to its spectacular picture quality, full suite of gaming features and impressive built-in sound.

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.
