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.

After just two years, more than a fifth of PC gaming monitors use upgraded OLED panels, according to a pre-CES briefing.

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.
