The new panel’s innovation centers on a Primary RGB Tandem structure, which is LG Display’s proprietary technology that uses independent stacks of RGB elements to produce light. It had previously used a three-stack light source, with two layers of blue elements emitting relatively short energy wavelengths alongside red, green, and yellow elements in a single layer.
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.
