What's the difference between CCFL lit and LED backlit screens on laptops?

Does anyone know the answer to this?

I've heard LED backlit screens are lighter, brighter/sharper and consumes less energy so the battery lasts a bit longer. Is this true?

Also, it's more expensive than CCFL, but is it actually worth the extra $$?

Thanks!

Well, maybe. CCFL is brighter (at first) but they do loose some of that over time.
CCFL has these advantages over most LED backlights

Higher Brightness and Contrast (at first)
Longer Lifetime (Over 50000 hours)
Low Power Consumption
Low Heat Generation
High Color Rendering

They do however fade over time and may at some point need to be replaced.
They are better lighting. LEDs require MORE power UNLESS they are the PWM type. Then the LED wins.

Here is a great place to SEE the difference.
