OLED Tunes its Colors for Sunlight-Style Illumination

(PhysOrg.com) -- Scientists have developed a lighting device that can change its color temperature throughout the day, matching the natural daylight chromaticities produced by the sun. Currently, no other type of lighting device is capable of producing this wide a span of sunlight-style illumination, which could make the new technology an attractive future high-quality lighting source. http://www.physorg.com/news166945490.html


This chart shows the color temperature of sunlight at different times of day, along with the color temperatures of various lighting devices: candles, incandescent bulbs, mercury lamps, fluorescent tubes, LEDs, and the new sunlight-style OLEDs. Image credit: Jou, et al.

hmm.. it it just looks like they took a warm white led, and are overpowering it.. though 8V seems like a stretch. I wonder what heatsinking it uses, or driver?

oh wait.. OLED.. hmm. I don't know anything about their behavior.

Don't OLEDs have a lifetime of about 1000 hours? The sunlight style illumination is nice, but with that kind of lifetime, you might be better off with a skylight.

Geez, it's an emerging technology. Cellphones aren't the size of bricks anymore either.
