LG verifies blue PHOLED tech, bringing the power-efficient, long-lasting "dream OLED" closer to market

Forward-looking: LG Display has become the first company to verify the commercialization of blue phosphorescent OLED panels. With the panels ready for mass production, LG says it has taken a significant step closer to realizing a "dream OLED" display: an OLED panel that achieves phosphorescence for the red, green, and blue subpixels. In OLED panels, the blue pixel color is more inefficient and has a shorter lifespan than red and green. One of the main contributors to burn-in is the blue pixel and how it emits light compared to red or green pixels. OLED pixels use organic compounds that glow via either phosphorescence or fluorescence. Phosphorescent emitters are usually more power-efficient and age more slowly, so many OLED panels employ them for the red and green sub-pixels. Blue sub-pixels, however, still rely on the less efficient fluorescent process. Because blue light needs extra power to match the brightness of red and green, those pixels wear out faster, making screens more pro ... Read full article.
