LG Unveiled 4th Generation OLED Panels
LG Displays has introduced the fourth generation of OLED panels for TVs, the main feature of which is the use of Primary RGB Tandem technology. It provides a maximum brightness of up to 4000 nits.
In addition to increasing the maximum brightness, LG Display has improved the color brightness of the latest generation of OLED panels. Color purity is enhanced by separating the red, green, and blue elements – the three primary light colors – into separate layers, resulting in a color brightness of 2,100 nits, 40% better than the previous generation (1,500 nits).
Because the screen reflects ambient light in a bright room, blacks can appear gray, or overlapping displays of neighboring objects can interfere with viewing.
LG Display has developed a unique film to eliminate this inconvenience for customers. It compensates for light reflected from the screen surface and absorbed and reflected inside the panel.
The screen’s color gamut changes dramatically when the ambient light becomes brighter. However, this TV panel has virtually no color change and provides 100% color accuracy at 500 lux.
With this ultra-low-reflection technology, the fourth-generation OLED TV panel blocks 99% of internal and external light reflection, creating a perfect black color even in bright daylight.
LG’s new displays are designed primarily for TVs with artificial intelligence that can analyze images in real-time and enhance them to 8K resolution and HDR.
LG has replaced the small lens array layer on the panel surface (MLA) with a new Primary RGB Tandem structure. This structure includes four stacks to create the luminous element, two layers of blue elements, and separate layers of red and green elements.
This change represents a step up from the third-generation panel, which combined the red and green elements into a single yellow layer.
Maximum color brightness has been improved by 40%, and the panel can now reach 2100 nits. In full-screen mode (100% APL), the brightness is 400 nits, a noticeable increase from the third generation’s 250 nits.
At the same time, LG has achieved a 20% reduction in power consumption thanks to the 4-layer structure and improvements in diodes and power systems.
The developers explain that the new generation displays are 33% brighter than their predecessors and can produce a picture with a maximum brightness of 4000 nits. Such displays are optimized for the current “AI TV era.”
“The structure of the new generation panels allows the light source to be divided into blocks, adding two layers of blue elements and independent layers of red and green elements. This allowed us to increase the maximum brightness by increasing the amount of light,” LG Displaytold.
The following features characterize primary RGB Tandem:
- Increased brightness: the technology allows displays to reach a maximum brightness of up to 4,000 nits, 33% higher than the previous generation.
- Improved color reproduction: Separating the red, green, and blue RGB elements into separate layers has increased color brightness to 2100 nits, 40% higher than the previous generation.
- Energy Efficiency: the new design and power supply system has improved energy efficiency by 20%.
- Anti-reflective coating: reduces light reflection and improves contrast, especially in bright surroundings.

LG Display is using 4th generation OLED panels this year to consolidate its dominance in the premium TV market. The company then plans to gradually apply its Primary RGB Tandem technology to its lineup of OLED gaming monitors, targeting the high-end gaming market with a diverse range of panels.
