PMOLED Displays

What is OLED ?

Organic Light-Emitting Diode (OLED) Display Panel, or Organic Electroluminescence (OEL), possesses the new generation technologies that other flat displays are hard to accomplish – brighter and clearer full colour images with more agile responding speed.

How does OLED emit light ?

The basic structure of OLED is a sandwich formed with a thin and transparent semi-conducting anode of Indium Tin Oxide (ITO) and a metal cathode on both sides of an organic substrate. The organic material comprises hole transmission layer (HTL), emitting layer (EL) and electronic transmission layer (ETL).

When a proper voltage provided by the battery (low voltage property) is applied, holes injected in the anode and electric charges from the cathode meet and combine at the illuminating layer and excite electroluminescence; structure of the organic layer and design and choice of the anode and cathode are key factors to the light emitting efficiency of the OLED device.

The advantages of using OLED
  • Wide Range of Visibility: Good visibility from long distance; wide viewing angle.
  • Small Size: Thickness down to 1.8 mm; Pitch size smaller than for any other technology.
  • Image Quality: High colour saturation, high contrast, and high speed.
  • Low Power Consumption: efficient transformation of electricity into light low heat output.
Applications of OLED Technology

Today OLED displays are used in number of devices that require electronic display panel. Among most popular types of application are:

  • Personal Digital Assistants (PDAs);
  • Audio/Visual display systems;
  • Mobile telephones;
  • Portable games;
  • Personal care appliances;
  • Household goods;
  • Dynamic information displays;
  • Medical handheld devices.

However, number of possible applications is growing everyday and is not restricted by industry or type of product.
