Articles about 'light-emitting diode (LED)'

Fast data transmission could be delivered in homes and offices through light emitting diode (LED) bulbs, complementing existing communication technologies and networks.

Researchers have designed smart, colour-controllable white light devices from quantum dots – tiny semiconductors just a few billionths of a metre in size – which are more efficient and have better colour saturation than standard LEDs, and can dynamically reproduce daylight conditions in a single light.

Cracked and blurry phone screens could someday be a thing of the past, suggests a new study from the University of Cambridge and the University of Queensland, Australia.

An international group of researchers has developed a new technique that could be used to make more efficient low-cost light-emitting materials that are flexible and can be printed using ink-jet techniques.

Researchers have set a new efficiency record for LEDs based on perovskite semiconductors, rivalling that of the best organic LEDs (OLEDs). 

Researchers have developed all-electrical ultra-thin quantum LEDs, which have potential as on-chip photon sources in quantum information applications, including quantum networks for quantum computers. 

Colourful LEDs made from a material known as perovskite could lead to LED displays which are both cheaper and easier to manufacture in future.

Cambridge is to lead the technology roadmap towards a €1 billion European programme to conduct research on graphene - a versatile substance, stronger than diamond, which researchers say could trigger a “smart and sustainable carbon revolution”.

A remarkable light-emitting material, gallium nitride, could slash electricity consumption, purify water and kill superbugs.

The path from innovation to impact can be long and complex. Here we describe the fascinating story behind the development of a new type of electronic reader.
