2. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   In an organic light-emitting diode , the electroluminescent material composing the emissive layer of the diode is an organic compound. The organic material is electrically conductive due to the delocalization of pi electrons caused by conjugation over all or part of the molecule, and the material therefore functions as an organic semiconductor ...

3. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence". The wavelength of the light produced depends on the energy band gap of the semiconductors used.

4. OLED - Wikipedia

   en.wikipedia.org/wiki/OLED

   An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, [1] [2] is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current.

7. Phosphorescent organic light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Phosphorescent_organic...

   Phosphorescent organic light-emitting diodes (PHOLED) are a type of organic light-emitting diode (OLED) that use the principle of phosphorescence to obtain higher internal efficiencies than fluorescent OLEDs. This technology is currently under development by many industrial and academic research groups.
