Blue light is vital for light-emitting devices, lighting applications, as well as smartphone screens and large screen displays. However, it is challenging to develop efficient blue organic ...

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 ...

Chemists have engineered a new molecule that can help organic light-emitting diodes (OLEDs) produce purer colors, potentially ...

Seoul National University researchers have developed an ultra-low-voltage electrochemical organic light-emitting transistor ...

Overcoming the light-emission limitations of conventional organic semiconductors through ultra-low-voltage operation.

Miniaturization ranks as the driving force behind the semiconductor industry. The tremendous gains in computer performance since the 1950s are largely due to the fact that ever smaller structures can ...

At-home light-emitting diode (LED) devices are effective for treating acne, according to a research letter published online March 5 in JAMA Dermatology. Sherry Ershadi and John S. Barbieri, M.D., from ...

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 ...
