I heard that a friend of a friend visited the Prolight + Sound and Musikmesse in Frankfurt last week. He was talking about some kind of new LED technology which was previewed there, but doesn't remember much about it, apart from that he thinks it is a "Laser reactive LED" and that it "requires no cables". This sounds like it could be interesting - does anyone here know anything about it ?
New kind of LED technology ?

Hi
Have you tried a Google search yet. Generally if you can't make some reasonable hits via Google then it's either still deep in R&D Alpha stage or a mistaken identity or sheer speculation or fluff. It sounds interesting though.

Hmm. So you shine a laser at it and it glows really bright? Doesn't sound like an LED to me.. Maybe he was talking about those 3D holographs or something..

Hmmm ... actually just an inefficient solar cell.
Edit: If you have the time and interest, Sams Laser FAQ is a fascinating read.

Thanks for that, FlashlightOCD (and the others), I have a gut feeling that your link may be the answer. I'll forward it and see if it jogs any memories.
Very interesting, while the process as described maybe inefficient and expensive, there may be a germ of an idea there which somebody has used to produce a commercial product. What Sam describes is a process using single LEDs and a laser pointer. Bearing in mind the continuing advances in both technologies, would it not be possible to create some kind of video display, using a carefully aimed/scanned higher power laser, shining onto LED chips ?
I have no real technical knowledge in this field, so any thoughts would be welcome.
And yes, Sams Laser FAQ is a most fascinating read, I'm not really a "laser guy" myself, but there is much in there that stimulates my imagination - thanks very much for posting it /ubbthreads/images/graemlins/smile.gif

Just had a thought -
If you projected a green-laser-pointer-based light show onto a glow sheet, would it tend to even out the flicker?

The depressingly low efficiency of the conversion - coupled with the need for a high-powered laser - make the display concept highly unlikely.
DLP, plasma screens, and LCD displays have far more promise as new/evolving display technologies right now.
