Flexible LEDs that will make it possible to use them in never-before-seen types of displays and configurations. In general, organic LEDs (used for applications like cell phone screens) are smaller, cheaper and easier to produce, but inorganic LEDs (like you might see on an outdoor electronic billboard) are brighter and more durable. This new technology combines the best attributes of both types of LEDs and makes it possible to use them in thin, flexible arrays that were impossible with inorganic LEDs until now. The new LEDs are manufactured by depositing light-emitting material onto a wafer layer, with a “sacrificial layer” between them. The sacrificial layer is dissolved away (leaving the wafer free to be used again, unlike traditional LED manufacturing methods) and the LEDs can then be mounted to just about any substrate.
