OLEDs are essentially diverse from LEDs, which might be dependant on a p–n diode crystalline good structure. In LEDs, doping is used to make p- and n-locations by shifting the conductivity in the host semiconductor. OLEDs do not employ a crystalline p-n structure. Doping of OLEDs is used to extend radiative efficiency by immediate modification on the quantum-mechanical optical recombination price. Doping is In addition applied to determine the wavelength of photon emission.[seven]

Coloration filters can also be implemented into bottom- and top rated-emission OLEDs. By including the corresponding RGB color filters once the semi-clear cathode, even purer wavelengths of light could be acquired. Using a microcavity in prime-emission OLEDs with colour filters also contributes to a rise in the contrast ratio by reducing the reflection of incident ambient light-weight.
