OLED: Light that keeps the vampires away

LG Chem released an important PSA for the world: OLED (organic light-emitting diode) lighting can help us fight the inevitable vampire attacks.

This video is a fun play on an important topic — how light affects our body, and how technology can help us achieve artificial lighting that is closest to natural light. OLEDs use organic compounds between electrodes to emit light, and are used mostly in televisions and cell phones. These are two devices that have come under the spotlight in terms of how they affect the body. As OLED does not need a backlight, perhaps using this technology in those devices could help decrease the detrimental effects of blue light on human circadian rhythms and the brain.

One manufacturer has designed a desk lamp using OLED technology. It’s a bit pricey but considering the biological implications, do you think it could be worth it?

One fairly obvious disadvantage to OLED is the lifespan — organic matter has a considerably smaller lifespan than plastics. Technology is sure to catch up, but how can you see using OLED? Outside of fighting vampires, that is.
