Optical components could benefit from a blue LED which offers enhanced coupling efficiency, stronger light emission, and a more uniform optical power output. Researchers from the Republic of China say ...

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 ...

The human eye can see any coloras a mixture of blue, red, andgreen. The circuit in Figure 1 producesall three colors through an Avago ASMT-YTB0tricolor LED. You can produce a widerange of colors by ...

(Nanowerk News) Light-emitting diodes (LEDs) have revolutionized the displays industry. LEDs use electric current to produce visible light without the excess heat found in traditional light bulbs, a ...

The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes, according to new tests. Both technologies pass ...

LEDs led to the high-definition viewing experience we've come to expect from our screens. A new type of LED that utilizes spintronics could take displays to the next level. Light-emitting diodes (LEDs ...

This LED emits light under forward bias in an ultra high vacuum chamber allowing simultaneous electron emission energy. Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news ...

Household and commercial lamps are designed to emit a broad spectrum of light composed of many wavelengths. But LEDs typically emit light of just one wavelength, which is determined by the energy gap ...

Assuming position as the brightest single-chip LED on the market, the KLC8 series delivers 250 lumens at a drive current of 1A. It also delivers an impressive luminous efficacy of 100 lumens/W at 350 ...

Engineers at the University of Michigan have created a new electrode that allows OLED panels to emit up to 20 percent more light. The researchers believe the breakthrough could help extend battery ...

You all know that incandescent bulbs are pretty inefficient, converting only 10% of electricity into light -- and 90% into heat. Light-emitting diodes, or LEDs, could soon replace incandescent and ...
