Being commercialised as early as next year is very appealing! Seems this is a very good breakthrough to the lighting industry. With large scale lighting this surely is a better choice for HBLED! How about the electronics driving this kind of display? A pure DC voltage source or current source or still good with AC?

I welcome alternative technologies to create light, and hope that FIPEL will turn out to be commercially viable, but does Wake Forest hire used car salesmen to be their researchers? When they equated LEDs with discos...wow, guys.

Nothing in the press release described the electrical signal that makes the material glow. But that certainly does matter, possibly quite a lot. CFL devices have that negative resistance function, and they change a whole lot as they warm up. So it would have been quite valuable to have a description as to just what sort of drive this material requires. And then there is one more question, which is: does it ever "wear out"?

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
