LG Display recently proved it can make blue phosphorescent OLED panels for everyday devices. The company worked with Universal Display Corporation to create this new screen technology, marking the first time anyone has made blue phosphorescent OLEDs ready for mass production.
Regular OLEDs use fluorescence, which wastes about 75 percent of energy. Phosphorescence saves all energy, but making blue light this way was difficult until LG solved the problem. Their new design uses two layers—one with blue fluorescence and one with blue phosphorescence—cutting power use by 15 percent without losing quality.
LG already has patents in South Korea and the United States for this technology. The company plans to show off these new screens at SID Display Week 2025 in San Jose. These panels target phones and tablets but could help power future AI computers and AR/VR headsets that need better, more efficient displays.
