Explanation:

An organic light-emitting diode (OLED) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound that emits light in response to an electric current. OLED displays can use either passive-matrix (PMOLED) or active-matrix (AMOLED) addressing schemes. Active-matrix OLEDs (AMOLED) require a thin-film transistor backplane to switch each individual pixel on or off, but allow for higher resolution and larger display sizes. Molecules commonly used in OLEDs include organometallic chelates (for example Alq3, used in the organic light-emitting device, fluorescent and phosphorescent dyes and conjugated dendrimers.
