LG becomes the world’s first to mass produce the “perfect OLED display”

LG Display has achieved a breakthrough that the industry has been working toward for years. The company is the first in the world to mass-produce blue phosphorescent OLED panels, a key component to creating a truly perfect OLED display in which all three base colors are powered by energy-efficient phosphorescence.

What LG came up with and why it matters

Development has been underway for eight months in collaboration with Universal Display Corporation (UDC). The new type of panel will debut at SID Display Week 2025 in San Jose.

The technology is based on a hybrid architecture: a two-layer structure where the bottom layer remains fluorescent for stability and the top layer remains phosphorescent for energy efficiency. This approach has reduced power consumption by about 15% without sacrificing brightness or lifetime.

At the heart of the technology is a hybrid architecture, where the bottom layer remains fluorescent for stability and the top layer phosphorescent for energy efficiency.

The use of blue phosphorescent materials was made possible by UDC’s PHOLED technology. It utilizes organometallic compounds with heavy metals (e.g. iridium) that allow both types of excited states – singlet and triplet – to be engaged. The result is nearly 100% light emission efficiency.

Where this will come in handy

In the first stage, the new panels will be used in compact devices: smartphones, tablets, wearable electronics and possibly foldable models. In the future, the technology will be used in AI-enabled devices, AR/VR headsets and ultra-thin laptops.

Interestingly, it was LG that beat Samsung, which was actively working on a similar solution and was going to apply it to the upcoming Galaxy Z Fold 7 and Flip 7. But now LG has taken the lead – and it’s an important milestone for the entire industry.

Why the perfect OLED became a reality

Blue phosphorescent OLEDs are the last missing element of truly energy-efficient displays, where all three base colors use phosphorescence. This means:

• lower battery consumption;
• brighter screens;
• the ability to create thinner devices;
• better image quality.

After decades of research, the industry has finally achieved what seemed impossible a short time ago. The perfect OLED is no longer a concept – it’s a reality and will soon be in consumer devices.
