LED Backlight
Here are some of the avantages of LED Backlighting VS CCFL Backlighting
Longer life time (An estimated 60K to 100K hours) VS (20K to 30K on the CCFL)
DC, there is no need for an inverter and there is no noise produced to interfere with external circuits
Easier to control dimness
Faster on and off response time
Can operate at extreme cold temperatures. See what to expect when operating an monochrome display at cold temperatures
So if you are shopping for a new laptop check and see if it is LED Backlit...Your laptop will last longer, be quieter and use less power...hope this helps
