LED light-emitting diode light-emitting diode led is a General name of the technology is semiconductor device used in light-emitting devices room lighting lights car lights decorative lights. Unlike conventional lamps Lenin emitting broad spectrum light led initially lies in a narrow range and depends on the chemical composition of the used semiconductors. Led bulb feature high brightness and energy efficiency but have limited resource and inclusion. Until recently, LEDs were very expensive and now without them I can not do any turning on a light.
Thanks to the boom of wearable electronics rapid development taking place in the production of electronic displays are designed for integration into clothing and textiles. Currently, however, for the production of LEDs designed for use as an elastic and deformable surfaces, on clothes and even displays specifically designed to meet the biocompatibility are still used solid materials for the protective sheath electroluminescent material.
Research staff, University of Manchester sir Andre Geim and a native of the USSR sir Konstantin Sergeevich Novoselov, one of the creators of graphene at the moment announced the creation of a flexible LED display based on graphene in the above image, he is not proving that two-dimensional materials is also quite suitable for creating flexible, transparent displays that will be used in more energy efficient electronic devices.
This year the game Tetris turns 30 years old. Yes you heard it 30 years ago Alexey Pajitnov created this incredible game. In honor of this event the students of Drexel University hosted a unique event in which anyone could play Tetris on the surface of a skyscraper.Read more
LEDs have proven themselves as everyday light sources. They are more environmentally friendly, consume little energy and last longer than conventional bulbs and give more light. However, the LEDs has a drawback which is their sensitivity to voltage drops. But scientists from the Fraunhofer Institute in Germany have found a way to get rid of this drawback.
Light-emitting diodes LED has become rather widespread nowadays. Researchers are trying to create the smallest diode as the main feature of led is its small size thanks to which they can be used as point light sources.
Philips has joined forces with the company Desso to create light transmitting
