What is an OLED?


OLED (Organic Light Emitting Diodes) is a flat light emitting technology, made by placing a series of organic thin films between two conductors. When electrical current is applied, a bright light is emitted. OLEDs can be used to make displays and lighting. Because OLEDs emit light they do not require a backlight and so are thinner and more efficient than LCD displays(which do require a white backlight).



OLEDs are not just thin and efficient - they can also be made flexible (even rollable) and transparent.

OLED vs LCD
  • Lower power consumption
  • Faster refresh rate and better contrast
  • Greater brightness - The screens are brighter, and have a fuller viewing angle
  • Exciting displays - new types of displays, that we do not have today, like ultra-thin, flexible or transparent displays
  • Better durability - OLEDs are very durable and can operate in a broader temperature range
  • Lighter weight - the screen can be made very thin, and can even be 'printed' on flexible surfaces

The future - flexible and transparent OLED displays
  • Curved OLED displays, placed on non-flat surfaces
  • Wearable OLEDs
  • Transparent OLEDs embedded in windows
  • New designs for lamps
  • And many more we cannot even imagine today...


OLEDs are not just thin and efficient - they can also be made flexible (even rollable) and transparent.
OLED displays have the following advantages over LCD displays:
It turns out that because OLEDs are thin and simple - they can be used to create flexible and even transparent displays. This is pretty exciting as it opens up a whole world of possibilities:
