Challenges In OLED Research and Development III: Solution-Based Materials

Solution based materials are a different way of processing the conventional OLED materials. So conventional OLED materials are processed by vacuum thermal deposition or heating up a powder in a crucible and evaporating it onto the substrate. Solution process materials are dissolved in a variety of solvents and then they can be coated by spin coating for lab sized experiments, or ink-jet printing, or slot-die coating, or a variety of other printing methods.

Challenges In OLED Research and Development II: Light Extraction

Light extraction is the process of removing light from the device itself. So when the device emits a photon, it gets trapped in the glass, in the organic layers themselves in the metals. And the-- what our challenge is, is to get all of that light into the viewing angle. So that when somebody sees the OLED they're seeing the full efficiency of that device. Rather than having light lost in the various segments.

Challenges In OLED Research and Development: Emitters

The thing that actually converts electricity into light is the emitter itself. So there are a number of scientific challenges that are still out there in OLEDs, particularly in emitters. Even though you can go to the cell phone store and buy yourself a cell phone that's powered by OLED emitters, and active matrix OLEDs are present in cell phones and in televisions, and it leads people to think that all of the issues are solved.

OLEDs are based on organic (carbon-based) materials. Unlike LEDs, which are small point sources, OLEDs are made in sheets that provide a diffuse-area light source. While developing rapidly, OLED technology is less mature than LED technology, whose rapid advancement has created a moving target for OLED products in terms of lighting performance and pricing. Still, OLED manufacturers are optimistic that with a few key breakthroughs, OLEDs will offer a value proposition complementary with LED lighting approaches.

Like any new technology, LED lighting must demonstrate a compelling value to buyers before it begins to win sizeable market share from the incumbent technologies it will replace. Over the past decade, research and development have yielded impressive improvements in the cost, color performance, light output, efficacy, reliability, lifetime, and manufacturability of LED products. Looking at LED packages specifically, the cost in dollars per kilolumen ($/klm) has been declining rapidly since 2005 at a rate of around 20% per year. As a result, LED lighting products have become competitive in almost every lighting application, but there is still room for improvement.
