    EL backlights aren't particularly new; they have exisited ever since 'indiglo' watches came out. However they are way too dim for 'ultra bright' applications like this. They are also generally not white which makes them unsuitable for backlighting color LCD's. The major advantage of an EL backlight is the power requirement which is why you see them very often on portable devices with monochrome LCD screens. The iPod (non color) is an example of a relatively white EL backlight screen that is about the current limit of the technology in terms of color and brightness.

    If you do want a wacky and useful alternative idea, there are actually companies which produce fiber optic backlights. The obvious advantage of a fiber optic backlight are that they let you use conventional, very bright, cheap, (and sometimes very hot) light sources to backlight an LCD. They are also inexpensive to customize for different size applications since installation options are very flexible. The downside is that they are expensive, somewhat fragile, and would not fit into an LCD case if that is the application we are going for.

    'tis true what the others said. EL is ****e. Not bright enough and the life is too short. EL panels are nice to power though. They go dim very quickly compared to CCFL and EEFL (even better).

    But i might bid on the girl he is selling....http://cgi.ebay.it/ws/eBayISAPI.dll?...ay_Pr4_PcY_BID

    got the lcd in front of the led's..... without any add'l diffuser she has hot spots.... not unusable but not great either..... she's pretty bright next to my laptop which has an average screen I guess... 200 nits or so...

    I can crank the brightness in the control panel.... not the led brightness but the graphics control.... I can get it to be super bright, but then it looks all washed out..... with the brightness turned down she is still pretty bright & colors are good.....more light would make it great

    there is some coloration from the copper too... I think I'm going to get the 16 more luxeon 1's... that wil fill the gaps that are in the lights as-is & help it overall... the copper coloration is mostly from the darker spots that don't have led's...

    I still need to find some type of diffuser..... I bought something that didn't work to well.... it focused well when I lifted it 3" from the housing... but when I went closer I could still see the spots... what should I try for diffusers? any ideas?
