LG Display became the first company to verify blue phosphorescent OLED panels at production scale. The company solved a 20-year problem that stumped display makers worldwide. OLED displays use two light methods: fluorescence, which reaches only 25% efficiency but works simply, and phosphorescence, which reaches 100% efficiency but requires complex engineering. Red and green phosphorescence already existed, but blue needed extra work because it uses more energy.
LG created a special two-layer design with blue fluorescence on the bottom and blue phosphorescence on top. This combo uses 15% less power than the current screens without losing stability. The company filed patents in Korea and America for this method. They finished testing with partner UDC to confirm it works for real products.
Visitors can see these new screens at Display Week 2025 in San Jose starting May 11. LG plans to use the tech first in small screens for phones and tablets. Many future devices like AI computers and headsets need both sharp images and long battery life, making this perfect timing. The company believes this completes what experts call the dream OLED that uses phosphorescence for all three colors.
