Philips reached a new milestone in OLED lighting this week: the first AC-powered OLED module. In the past, OLED technology required DC voltage — a requirement that meant OLED panels had to contain expensive switching mechanisms. But the new AC-powered OLEDs can be plugged directly into a standard wall socket, potentially bringing down the cost of the low-energy lights.
OLEDs are still too expensive for commercial lighting, but Philips’ discovery might just change that. And once ultra-attractive OLEDs become cheap enough for mass consumption, few people will complain about the death of incandescent bulbs.
