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 ...

An upconversion organic light-emitting diode (OLED) based on a typical blue-fluorescence emitter achieves emission at an ultralow turn-on voltage of 1.47 V. The technology circumvents the traditional ...

Tokyo, Japan – Scientists from Tokyo Metropolitan University have developed a new electrode material for deep-ultraviolet (DUV) light-emitting diode applications. They used a cutting-edge deposition ...

They’re in your phone, TV, car headlights, remote controls—even traffic lights. LEDs (Light Emitting Diodes) are everywhere.

Eric Franklin led the CNET Tech team as Editorial Director. A 20-plus-year industry veteran, Eric began his tech journey testing computers in the CNET Labs. When not at work he can usually be found at ...

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 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 ...
