The discovery of the visible light-emitting diode (LED) 50 years ago by Holonyak and Bevacqua and the associated demonstration of the viability of the III-V semiconductor alloy created a foundational ...

Unlike filament lamps, where electrical energy must be converted into heat before light can be produced, Light Emitting Diodes (LEDs) are able to transform electrical energy directly into light ...

A new pixel circuit consisting of eleven n-type IGZO transistors (TFTs) and four capacitors is proposed and applied for micro light emitting diode (MLED) displays. The circuit is driven by pulse ...

Diodes are electronic components that can be used to regulate the voltage in circuits and to make logic gates. Light-emitting diodes (LEDs) give off light and are often used for indicator lights ...

Many people believe that the LED was discovered by US researchers working in the 1960s. In fact, Henry Round at Marconi Labs noted the emission of light from a semiconductor diode 100 years ago ...
