The invention of a water-resistant, transparent, and flexible organic light-emitting diode (OLED) that emits and transmits light even when exposed to water could pave the way for a new wave of more ...

Belgium-based research and innovation hub Imec has developed a new type of perovskite LED stack, which, it says, emits light one thousand times brighter than state-of-the-art OLEDs. This result, say ...

Light can be produced and/or controlled electronically in a number of ways. Among the widely used of all the different types of semiconductor diodes are the Light Emitting Diodes or LEDs. It is a PN ...

RedShark Replay: The white heat of technology - Phil Rhodes talks about white light and a possible means of obtaining it with the minimum possible use of power. We've discussed white-emitting LED ...

The advantages of light-emitting diodes (LEDs), such as their tiny size, low cost and excellent power efficiency, mean they are found everywhere in modern life. A KAUST team has recently developed a ...
