OLED - Wikipedia
An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, [ 1 ][ 2 ] is a type of light-emitting diode (LED) in which the emissive electroluminescent layer is an organic compound film that emits light in response to an electric current.
How OLEDs (organic LEDs) work - Explain that Stuff
2022年9月1日 — OLEDs work in a similar way to conventional diodes and LEDs, but instead of using layers of n-type and p-type semiconductors, they use organic molecules to produce their electrons and holes. A simple OLED is made up of six different layers. On the top and bottom there are layers of protective glass or plastic.

2020年8月14日 — OLED efficiency is a key-issue for organic flat-panel displays and solid-state lighting, not only from a sustainability perspective but also to reduce fast device degradation that can occur at high brightnesses.
OLED: Theory and Principles - Wiley Online Library
This chapter provides a brief history of organic light-emitting diode (OLED) and describes the basics of OLED, including processing methods and theory. It emphasizes OLED aspects that are at most related to microdisplay applications. In an OLED device, charges are electrically generated by applying a potential to the structure electrodes.

The fundamental device structure of OLEDs is very simple, consisting of an anode, some organic layers and a cathode. The OLED has several attractive features such as low driving voltage, high efficiency, wide color variation, and fast response speed.
OLED Basics - Department of Energy
An OLED is a solid-state device consisting of a thin, carbon-based semiconductor layer that emits light when electricity is applied by adjacent electrodes. In order for light to escape from the device, at least one of the electrodes must be transparent.

The basic principle is identical. OLED emits light by conducting electricity to the organic materials that are sandwiched between the electrodes. On the other hand, LED emits light by conducting electricity to inorganic materials that are sandwiched between electrodes.

2022年10月14日 — This chapter briefly introduces the light-emitting principle and basic structure of OLEDs, classifies representative luminescent OLED materials, and discusses the development and application prospects of OLED materials and devices.
[DISPLAY 101] #24 Principle of OLED Luminescence
2023年5月11日 — Essentially, the principle of OLED luminescence utilizes the electroluminescent phenomenon where energy generated by the difference between positive (+) and negative (-) charges is emitted in the form of light. When electricity is supplied to the OLED structure, positive charges injected from the anode migrate to the cathode, and electrons ...
