Last week LG Electronics officially launched its 2025 OLED TV range, where some of the high-end models reaching 4,000 nits. LG Display today unveiled the technology behind these new OLED displays.
LGD's so-called META 3 WOLED panels (which are the company's 4th-gen WOLEDs) achieve 33% higher brightness to each a maximum of 4,000 nits. The new panels adopt a new stack structure that has two layers of blue emitters and two more layers, one with red emitters and one with green emitters. LGD refers to this architecture as a "Primary RGB Tandem structure".
The new technology, in addition to increasing the maximum brightness, also increased the color purity, LGD says that the color brightness is increased 40% to 2,100 nits. The energy efficiency is also increased by around 20% (for a 65-inch panel).
Finally, LGD says that it has developed a special film that offsets both light reflected from the display’s surface and light absorbed and reflected inside the panel. With the advantage of this ultra-low reflection technology, the company’s fourth-generation OLED TV panel blocks 99% of internal and external light reflections, realizing perfect black just like in a movie theater with the lights off even in a midday living room setting (500 lux).
In addition to TV applications, LGD will gradually apply its Primary RGB Tandem technology to its Gaming OLED lineup, targeting the high-end gaming market with a diverse range of panels.
