What Is A Light-Emitting Diode? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. LEDs function by converting electrical current into ...

A light source created by a light emitting diode (LED). For decades, LEDs have been used as indicator lights on myriad products; however, starting in the 2000s, they began to replace incandescent, ...

A deep blue organic light-emitting diode (OLED) developed by researchers at Science Tokyo operates on just a single 1.5 V, overcoming the high-voltage and color-purity problems that have long limited ...

To be more energy efficient, many people have replaced their incandescent lights with light-emitting diode (LED) bulbs. However, those currently on the market emit a lot of blue light, which has been ...

A research team led by the School of Engineering of The Hong Kong University of Science and Technology (HKUST) has made ...

Now, physicists at Julius-Maximilians-Universität Würzburg (JMU), Germany, say they have made progress toward luminous miniature displays and, with the help of optical antennas, have created “the ...

This illustration depicts the QAO family dopant integrated into the organic light-emitting diode structure. By designing a molecule with a lower HOMO level than that of the host material, the ...
