assuming you mean LCD displays with LED backlights; some don't pulse the
LEDs but others do pulse them to dim specific parts of the backlight and
increase dynamic range of the display; however, as with fluorescent
tubes, the pulsing is usually fast enough to avoid flicker
LED backlit displays are now fairly common -- i've seen 22" versions
available in the mid-$200s and all of Apple's displays except the 30"
are now LED-backlit; it's worth considering them for a few reasons:
first, the color and brightness is more stable both long- and
short-term; second, LED backlights typically need less power; and third,
unlike fluorescent tubes, LEDs do not contain mercury
