Talk:OLED

fundamental
The article suggest that OLED is fundamentally different from inorganic LED. Seems to me not so fundamental. Both are based on radiative recombination of electron-hole pairs. LEDs using GaP, and other indirect gap materials, also use exciton recombination. Two layer materials can be described as pn junctions. In addition, non-radiative recombination due to defects is the usual cause for reduced emission with age. Gah4 (talk) 20:31, 2 January 2022 (UTC)

White OLED
After searching around for a bit the J Kido, M Kimura and K Nagai white light emitting organic electroluminescent device seems to have way less citations than what I expected, is it because the invention is kinda obvious or what? — Preceding unsigned comment added by Mirad1000 (talk • contribs) 22:42, 24 May 2022 (UTC)

Confusing Section in intro, perhaps could do with slight rewording for clarification?

 * OLED is fundamentally different from LED which is based on a p-n diode structure. In LEDs doping is used to create p- and n- regions by changing the conductivity of the host semiconductor. OLEDs do not employ a p-n structure. Doping of OLEDs is used to increase radiative efficiency by direct modification of the quantum-mechanical optical recombination rate.  Doping is additionally used to determine the wavelength of photon emission.

This section seems to contradict the rest of the intro, where OLED is described as a type LED technology (as it is in the article's infobox). The link simply points to the LED article. I'm not an expert at all on this topic, but perhaps it's meant to mean that OLED displays are "fundamentally different" from "LED" in the sense meant at LED display? Or, alternatively, perhaps it means that LEDs as found in OLEDs are different from conventional/regular LEDs as used in lighting (if that's a meaningful distinction to make here; again, I'm no expert). In any case, at present, the article starts by saying that an OLED is a type of LED (“An organic light-emitting diode (OLED or organic LED), also known as organic electroluminescent (organic EL) diode, is a light-emitting diode (LED) in which[...]”), and then proceeds to say that OLED is fundamentally different from LED. Both cannot be true; I think this could do with some re-wording/clarification. Perhaps I'm missing/misunderstanding something and there is no contradiction, but if that's the case then I believe the wording should be updated so that the more specific meaning (whatever it be) is more readily apparent. --Tomatoswoop (talk) 16:06, 30 July 2022 (UTC)

Banding
There's no mention of banding at low brightness values. I don't have any reliable source, for now 66.98.85.105 (talk) 16:30, 27 January 2023 (UTC)
