SOME MULTI-STRING LED MODULES come with a common-anode configuration. The commonanode connection reduces the number of wires between the LED module and its driver from 2N to N+1, where N is the number ...

Figure 1: Schematic illustrations of hole injection from graphene, device structure and fabrication steps for flexible OLEDs. We fabricated a series of small-molecule fluorescent OLEDs, including a ...

LED cubes are cool, but they’re usually pretty big and clunky. [One49th] set out to make one of the smallest LED cubes we’ve seen yet, and he’s shared how he did it in his Instructable! His first LED ...
