Knowledge in LEDs

LEDs (IV semester)

attached document contains notes of LED which is a type of special diode. These notes are prepared by Dr. Reenu Jain and are more than useful for someone who really wants to go in to the depth of the topic and clear concepts

ORGANIC LIGHT EMITTING DIODE -OLED

An organic light-emitting diode (OLED or Organic LED), also known as an organic EL (organic electroluminescent) diode, 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. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television screens, computer monitors, portable systems such as smartphones, handheld game consoles, and PDAs. A major area of research is the development of white OLED devices for use in solid-state lighting applications.
