QLED TVs are great for budget and mid-range shoppers, but it's worth considering how long one will last before you shell out ...

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 ...

Organic Light Emitting Diodes (OLEDs) have gained significant attention since researchers at Eastman Kodak pioneered the development of OLED technology in the 1970s and demonstrated the first ...

Light-emitting diode bulbs (LEDs) are energy-efficient and durable options. LEDs convert electricity into light instead of ...

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 ...

A process developed at ETH Zurich enables the massive miniaturisation of organic light-emitting diodes (OLEDs) in only one single step. The light sources are now smaller than the wavelength of the ...
