OLED (Organic Light-Emitting Diode)

OLED (Organic Light-Emitting Diode) Latest News

India is currently investigating LG Electronics and Samsung for allegedly paying lower tariffs on imported display parts  that go into making panels for OLEDs.

About OLED (Organic Light-Emitting Diode)

• It refers to a class of light-emitting devices where the emissive layer is composed of carbon-based organic molecules that glow when excited by an electric current.
• The OLED structure consists of a multilayer array of thin organic films sandwiched between two electrodes, at least one of which is transparent, allowing light emission.  When electrical current is applied, a bright light is emitted.  
• OLEDs differ from both traditional LEDs (inorganic diodes that emit light at specific points) and LCDs (which rely on liquid crystals and a backlight). 
• Instead, OLEDs are self-emissive surfaces, which means every pixel generates its own light. 
• OLED displays provide the best image quality, and they can also be made transparent, flexible, foldable, and even rollable and stretchable.
• An OLED display have the following advantages over an LCD display:
  • Improved image quality: Better contrast, higher brightness, fuller viewing angle, a wider color range, and much faster refresh rates.
  • Lower power consumption.
  • Simpler design that enables ultra-thin, flexible, foldable, and transparent displays
  • Better durability: OLEDs are very durable and can operate in a broader temperature range.
• Advanced OLED configurations include PHOLED (Phosphorescent OLED) variants, which use phosphorescent phosphors to increase light efficiency, and WOLED (White OLED), used in lighting technology to generate white light with a wide colour spectrum.
