Re: TI-H: Indiglo Backlight/keylight


Ok.  When I was looking through my magazines for LCD screens (for your
laptop!) I saw a section for EL inverters.  The inverter compatible with an
EL screen this size is about $13.  Go to www.digikey.com and look up part
number 73-1002-ND or 73-1009-ND.  I don't have measurements, but digikey
probably does.  Please, does anyone know where I can get an EL panel?
