Expectations Dim for OLED Lighting

High costs could keep white organic-light-emitting diodes off the shelf

3 min read

A new report suggests that organic light-emitting diodes, or OLEDs, won't come anywhere close to replacing conventional illuminators like incandescent and compact fluorescent lightbulbs in the foreseeable future. The analysis, conducted by Lux Research, a technology consultancy based in Boston, is marked by an extremely bleak projection of the worldwide OLED lighting market in 2020—a mere US $58 million in annual sales.

But experts from industry and academia and even other independent analysts aren't nearly so pessimistic, with one annual sales projection in the billions of dollars. Which future for OLED lighting comes to pass will depend on how much technology developed for OLED displays proves transferable to the lighting world.

Seventy-five years is a long time. It’s so long that most of us don’t remember a time before the transistor, and long enough for many engineers to have devoted entire careers to its use and development. In honor of this most important of technological achievements, this issue’s package of articles explores the transistor’s historical journey and potential future.
