    Kingbright makes them. They also do them in white.

  3. Farnell list several (www.farnell.com)
     
  4. Why in the world do you want to do that? Blue is a crummy color- the
    *worst* for making the display readable, and it will be relatively
    expensive.

  5. Deep down inside, you know it's cool! :)

    The sad thing is, that to someone like myself brought up on 20 years
    of only red, yellow or green, there is something about a blue led that
    *is* kind of cool.
     
  6. Yeah, I know, just trying to be the voice of reason here. I've got a
    blue backlit LCD display on my office stereo and I have to wheel
    halfway over to it on my Aeron just to see what &*&*$#$ station it's
    set to.

    Best regards,
    Spehro Pefhany

    I had a customer who insisted on a blue filter for a (green) VFD
    display. The filter material cost arms and legs, the display's brighness
    was reduced dramatically, and the customer was a happy chappie. He also
    made me change the square black buttons to round red ones. That improved
    the performance dramatically.

  8. Some time ago, I worked on a display panel for a military system. The
    display technology was AC plasma, which gives out a soothing orange glow
    without flicker or raster-scan artifacts. The specification for the
    equipment included an adjustable-intensity blue-green electroluminescent
    backlight, for which someone had apparently conjured up a reason. The
    proper setting for the backlight for best system usability and reliability
    was "Off".
     
  9. Gag.
     
  10. Thanx to All also to the international-blue-LED-detractor-party! ;-)
