TECHNOLOGY FEATURES

WOLEDs offer a set of new performance features simply not possible from incandescent and fluorescent lamps. While inorganic LEDs, currently under development for lighting applications, also offer attractive features, they are generally considered to be good “point source” lights while OLEDs are excellent diffuse emitters.

  • High power efficiency – Enabled by Universal Display’s high-efficiency PHOLED technology, WOLEDs have the potential to achieve > 150 lumens per Watt. At such levels, significant energy savings may be realized. Additional WOLED benefits may include reducing the consumption of non-renewable fossil fuel and greenhouse gas emissions.
  • Bright, uniform white color quality – With broad spectral emission, a color rendering index (CRI) of 70 or greater can easily be achieved at color temperatures ranging from the warm white of incandescent lamps to the cool white of fluorescent tubes and LEDs. With continued advances, WOLEDs should also provide long operational lifetimes for a variety of high-performance applications.
  • Color tunability and dimmability – Innovative WOLED architectures may enable custom tuning of a WOLED’s white light - allowing a room’s appearance to be changed from a cool to a warm white as desired. Brightness levels can also be adjustable and, unlike fluorescent lighting, will become even more efficient when dimmed.
  • Innovative form factor – WOLEDs intrinsically emit uniform light, making them excellent diffuse lighting sources. As lighting tiles, WOLEDs will offer a much thinner and safer form factor than those found in bulky and fragile incandescent bulbs and fluorescent tubes. When built on plastic and other flexible substrates, WOLEDs become ultra-thin, lightweight, and conformable, enabling a host of novel product uses. Integrated with our TOLED transparent OLED technology, WOLEDs could also be used as windows, providing sunshine during the day and lighting at night.
  • Environmental Friendliness – WOLEDs are a "green" technology. With excellent energy efficiency, WOLEDs may save significant amounts of energy helping to reduce our dependence on foreign oil and other non-renewable fuels, and, in turn, reduce impact on the environment. WOLEDs may offer additional environmental advantages over existing lighting technologies that contain hazardous substances and pose disposal problems.
