organic light-emitting diode
Học thuậtThân thiện
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
- a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers
