Benefits of OLED Displays

An organic light-emitting diode (OLED), is further development of LED technology in which the electroluminescent layer is made of an organic compound.

OLED technology and adoption has developed quickly in the last few years as OLEDS offer many advantages over both LED and LCD technology.

The Advantages of OLED

Unlike LCDs, an OLED display generates its own lights, therefore does not require back-lighting. This means that they will consume considerably less power. This is an important factor in mobile hand held devices where power consumption is an important issue.

Along with this OLEDs are:
  • Thinner
  • Lighter
  • More flexible than either an LED or LCD


Along with the lower power consumption and improved mechanical properties, an OLED is also brighter than an LCD or LED. This is due to its multi-layered conductive and emissive layers, it also does not require a glass support which absorbs light.

An OLED is now the display of choice in many commercial applications such as mobile phones, TV, monitors and digital cameras. With the current technology push to curved or flexible displays, OLED will have an important part of the future.

However, LCD and LED have an established following and their own advantages along with their longer lifetimes.

There is also the development of quantum-dot light emitting diodes (QLED) that is now entering the display arena in large size displays and is touted to be the long-term replacement of LCD.

It will be interesting to see if there is one winning technology for the future, or if the present situation will continue where requirements and size determine the correct technology.
