Being in the Electronics Field I have to totally agree.

These Blue LED's are the most invasive extreme light there is and why everyone has to load every available inch of unused space on Electronics with these things is beyond my comprehension.

I SWEAR ON MY GRAND CHILDREN'S LIVES that my Freggin Toaster has BLUE LED's on it !!!!!!!!!! A BREAD TOASTER now !!!!!!!!

I have gotten to the point where I either hide the device behind something, place something in front of it to block the light, or I cover the LED's with Blue Masking Tape that is just above being Heavily Opaque. At least this way, I can see the LED's that everyone now uses as Trouble Indicators or just Indicators, but they don't blind me.

I thought this silliness was just a Fad that would go away when people got fed up with all this Super Intense Blue Light in their faces, but it seems to be only getting worse.

And used too, most devices at least gave you a "Dimmer" option for these kinds of exterior lighting, but not any more .... and it seems the Brighter they are, the Better the manufacturer likes it .... why don't they either ask us, the Consumer or give us a way to Shut them Off or Dim Them ??

They are very very intrusive and visually angering at best.

Aren't white LED's just blue with phosphorous coating?

I just bought a new 50" Plasma (just in time for the UEFA cup and the Rice-LSU baseball super-regionals) - the new power supply has blue LED's that sit about two feet below the screen. I'm gradually migrating equipment over there and on my todo list is to obscure those lights.

Interesting new display technologies involve "quantum dots" that are supposed to make LED screens more efficient and also can produce white light for solid state use.

Quantum dots.

Let me tell you another funny story.

Back in 2003 I was doing a project for cleaning of sensitive surfaces (electronics, displays, etc). And one issue that kept coming up is how do you tell they are clean? So an investor in the process we were using (a retired NIH researcher) comes up w/ this idea using quantum dots. Very good idea IMO, so we worked together and submitted a patent.

Anyway, I was active w/ my photocatalyst interests at that time. One other application for those (different from my main interests) was dye-sensitized solar cells. I never liked dyes (organic chemistry, yecch) but with the other work on my mind, I began to speculate of using quantum dots in the same way as the dyes. Their size and high quantum efficiency should allow them to make better cells than the the dye-sensitized ones.

Yes, others have had that idea, and have made progress.

Fast forward to 2008. I work for a well known consulting company that is trying to leverage their S&T manpower to win new business. One opportunity is to pitch new ideas to GM. (Yes, that GM). So, I suggest that they consider quantum dot-sensitized solar cells on vehicles...as the paint. No obtrusive silicon panels, lots of surface area, easier integration into production lines.
Feedback I get from my co-worker is that they raised eyebrows at that one. They liked it.

The punchline?
