tuhin4u (Unstopable Lover + Mariana World DIAMOND member): An OLED (organic light-emitting diode) is a light-emitting diode (LED) in which the emissive electroluminescent layer is a film of organic compound which emits light in response to an electric current. This layer of organic semiconductor is situated between two electrodes; typically, at least one of these electrodes is transparent. *

tuhin4u (Unstopable Lover + Mariana World DIAMOND member): OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as mobile phones, handheld game consoles and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications. *

tuhin4u (Unstopable Lover + Mariana World DIAMOND member): There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light- emitting electrochemical cell (LEC) which has a slightly different mode of operation. OLED displays can use either passive-matrix (PMOLED) 0r active-matrix addressing schemes. *

tuhin4u (Unstopable Lover + Mariana World DIAMOND member): Active-matrix OLEDs ( AMOLED) require a thin-film transistor backplane to switch each individual pixel on 0r off, but allow for higher resolution and larger display sizes. *
