Image description

LED display, c 2006. Today's light bulbs are not very different from those made 120 years ago - they still produce more heat than light. But a new generation of lighting devices that use light-emitting particles is being developed. The most popular are LEDs. Scientists are trying to modify LEDs with special nanocrystals known as quantum dots to give cheaper and clearer light. The latest screens in mobile phones, digital cameras and medical video displays contain organic light-emitting diodes (OLEDs). These are thin, nano-size layers of light-emitting plastic. When electricity passes through them, they emit bright light of different colours to form an image. This makes them much more energy efficient than the commonly used liquid-crystal displays. ©SSPL/Science Museum
