Definition

Noun: A type of solid-state electronic device that emits light when an electric current passes through it. An OLED is a thin, organic material sandwiched between two electrodes; it produces its own light and does not require a separate backlight.

Examples of Usage
  • The smartphone features a vibrant OLED display with deep blacks.
  • OLED technology is popular in high-end televisions due to its excellent contrast ratio.
  • One advantage of an OLED screen is its potential for flexibility.
Advanced Usage
  • "OLED panel": Refers to the physical screen component itself.
    • The manufacturer sourced the OLED panels from a new supplier.
  • "OLED lighting": Refers to the use of OLED technology for general illumination, not just displays.
    • The future of interior design may include flexible OLED lighting panels on walls and ceilings.
Variants and Related Words
  • AMOLED (Active-Matrix Organic Light-Emitting Diode): A specific type of OLED display technology commonly used in smartphones, where each pixel is controlled by a thin-film transistor.
  • PMOLED (Passive-Matrix Organic Light-Emitting Diode): An older, simpler type of OLED display technology, often used in smaller screens like those on appliances or wearables.
  • QD-OLED (Quantum Dot OLED): A hybrid display technology that combines OLED pixels with a quantum dot layer to enhance color and brightness.
Synonyms
  • Organic LED: The full form of the acronym.
  • Organic light-emitting diode: The complete technical term.
Related Phrases
  • "self-emissive": A key characteristic of OLED technology, meaning each pixel generates its own light.
    • Unlike LCDs, OLED is a self-emissive technology.
  • "burn-in": A potential issue with OLED displays where static images displayed for very long periods can cause permanent, faint ghosting.
    • To prevent burn-in, the TV's software moves static elements like channel logos slightly.
Noun
  1. a self-luminous diode (it glows when an electrical field is applied to the electrodes) that does not require backlighting or diffusers
