Engineers Develop Flexible, Inorganic LED Display
The promise of OLED technology is that, unlike its inorganic counterpart, it can be used to create flexible and nearly transparent ultra-thin screens, opening up myriad possibilities for what we can do with displays and lighting. But just as market-ready OLED technology suffered a setback as Sony delayed its latest OLED television this week (only the world’s second commercial OLED TV, after ">Sony's XEL-1 set), engineers have devised a way to make cheaper, more efficient inorganic LED technology bend to their whims. Literally. Just what scientific innovation brought us this flexible LED technology? Make the LEDs smaller. But that’s easier said than done. LEDs are very efficient at converting electric charge to light, so the eye can detect even extremely small LEDs; therefore, in theory, even a display in which only a small fraction of the surface is actually covered by the LEDs is...
