What do LCD screens use for backlighting?

[zephyrprime]

Do they use flourescent lights? Electroluminescent? Does anyone know?

small lcd's use led's. large ones use flourescent lights.

at least i think

no, you're wrong. The big ones use a whole bunch of glowbugs and fireflies trapped in a flat jar.

I think.

Cold Cathode discharge lamps. Very similar to fluorsecent lighting. Newer solid state sources (from white LED's) are around the corner. These operate much cooler and with lower power consumption plus have a 100k+ hour MTBF!
