OLED - Organic Light Emitting Diodes

Electronic devices of many different types are part of every moment of our life and impose different constantly increasing requirements on the technology, so they can improve the battery life and performance of the devices in different conditions. One of the key components of such devices is the display, which, like everything else, is going through very fast evolution from one technology to another. Considering that PAC specialists need to use different mobile devices in substations and elsewhere in the field, the quality of the display is one of the key requirements.

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).

An OLED is a solid-state semiconductor device that is 100 to 500 nanometers thick or about 200 times smaller than a human hair. OLEDs can have either two layers or three layers of organic material; in the latter design, the third layer helps transport electrons from the cathode to the emissive layer.

OLED displays have the following advantages over LCD display

  • 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.
