Definition

Noun: A type of 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. It is a self-luminous display technology that does not require a separate backlight or diffuser.

Usage

An organic light-emitting diode is a key component in modern display screens. It functions as a thin, light-emitting surface.

Examples

• The smartphone features a vibrant organic light-emitting diode display with deep blacks.
• One advantage of an organic light-emitting diode is its potential for flexibility in future device designs.
• Manufacturers are improving the lifespan and efficiency of the organic light-emitting diode.

Advanced Usage

• In technical specifications: The term is used to specify the display technology, often contrasting it with LCD (Liquid Crystal Display) technology.
  • The television's picture quality is superior due to its organic light-emitting diode panel.

Variants and Related Words

• OLED: The common acronym for organic light-emitting diode.
  • Most high-end phones now use OLED screens.
• AMOLED (Active-Matrix Organic Light-Emitting Diode): A specific type of OLED display that uses an active matrix of TFTs (thin-film transistors) to control each pixel.
• PMOLED (Passive-Matrix Organic Light-Emitting Diode): An OLED display type that uses a simpler control scheme, suitable for smaller screens.

Synonyms

• OLED display
• Organic LED

Related Technical Terms

• Electroluminescence: The phenomenon of a material emitting light in response to an electric current, which is the core principle behind an organic light-emitting diode.
• Emissive display: A category of displays that generate their own light, such as an organic light-emitting diode, as opposed to non-emissive displays like LCDs which require a backlight.

Noun

1. a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers
