LG Display announces world's 1st commercial phosphorescent blue OLED
LG Display has successfully verified the production performance of blue phosphorescent organic light-emitting diode (OLED) panels for a mass production line for the first time in the world, the company said Thursday. This success comes about eight months after the company developed an OLED panel based on a blue phosphorescence emitter with Universal Display Corporation (UDC), an important step towards the display makers' long-time goal of an OLED panel that implements all primary colors of light — red, green, and blue — using phosphorescence. OLED panel emission methods are largely divided into fluorescence and phosphorescence. Fluorescence, which is technically simpler, emits light through immediately reacting to electricity, but has only 25 percent luminous efficiency. On the other hand, phosphorescence briefly stores energy from electricity before emitting light, allowing for 100 percent efficiency. This technically more challenging method reduces power consumption by one-fourth compared to fluorescence. Red and green phosphorescence were commercialized 20 years ago, but the displ
