I think that was a typo by FF, LCD = LED
Thanks. It was indeed a typo.
Is there an advantage to using LED backlights aside from ahieving a slimmer profile? Which is why they're being used in laptops.
I could imagine how they can turn off LEDs selectively to improve dynamic contrast (I remember reading about 1 HDTV that does this), but I don't think any PC monitors have implemented this.
In theory, LEDs don't have flicker, but in practice, CCFLS used in monitors refresh at 180Hz which is undetectable to the human eye.
Apart from better contrast, power consumption is another factor which is more important on laptops. Every bit helps on the desktop too I guess.
Update on LED backlit monitors. Looks like they're starting to trickle in to the market, and SPCR was quick enough on the nub to review the Samsung Syncmaster 20XL LED-backlit monitor
Unfortunately, power efficiency is not one of its strong suits, as the monitor draws about twice as much energy as comparable CCFL-backlit monitors, so much so that it necessitated a cooling fan in the casing.
According to Samsung, this is because even though white LEDs are more efficient than CCFL for luminance, they do not provide a good colour gamut. In notebook computers, this is usually not a major criterion, so white LEDs allow for slimmer, lower power models. As the 20XL is targeted at professionals, it uses a 3-LED system to generate a "white" backlight instead of using just white LEDs, hence the added power consumption.
