About a month ago, Apple made it known to their users that they would be using LED-backlighting in their future displays as part of the company's move to become environmentally friendly. The MacBook Pro's (MBP) corresponding update was expected to arrive this month. Now, for the MBP owners wondering how big a difference the new backlights are as compared to previous MacBook Pro models, we're informing you of a recently concluded test that should shed some light on the matter.

The guys over at Engadget have just gotten their hands on the 3rd-gen MBP, which sports the new LED backlight, and decided to do a brief visual comparison with its older kin, an 8-month old 2nd-generation MBP running on traditional cold cathode fluorescent tube (CCFL) backlights. The CCFL MBP's on the left, while the LED MBP's on the right (both set to full brightness):

  

Further notes in the comparison state that the new LED backlight featured crisper whites, although the screens weren't that much brighter. Another interesting detail the testers state is that at half-brightness, the LED MBP was dimmer. Needless to say, the new LED backlight should also beef up your laptop's battery life, although we haven't confirmed by how much yet.
