All so-called LED TVs are really just LCD TVs that use LEDs for their backlight. This backlight creates the light that allows the LCD to create an image. However, there are multiple ways these LED ...

Stacking light-generating layers in ‘tandem’ light-emitting diodes (LEDs) can enhance performance, but achieving efficient and stable tandem LEDs made with perovskite materials has remained a ...

The demonstration of an LED made from a single electrostatically doped carbon nanotube p–n junction with dramatically improved light-emission efficiency marks an important advance for carbon nanotube ...
