Last EL panel I designed a supply for was three panels 30 inches BY 120 inches.
They are going strong and haven't lost much light yet, But is has only been a
year and they are only on for 6 hours a day. That is about 2,000 hours.



A good alternative to an EL panel would be an LED back light. I've
seen ones which were made of a woven plastic fiber optic sheet that
was illuminated by an LED. Life should be virtually unlimited.
Something like this might be a good replacement

I have built such backlights for LCD displays. We used a single
injection moulding for our light pipe/spreader, and had all the LEDs on
the same pcb as the LCD driver, micro,switches etc
