Screen flickers at low brightness

There's nothing wrong with your iPads, almost [anything|http://www.youtube.com/watch?v=7Moniwv8ewU] with an LED backlight display will show it at low brightness.

LEDs don't actually dim like old CCFLs, they flicker at specific frequencies to appear as though they are dim. Some people are more sensitive to this than others. I see it on my LED backlit MBP and on my wife's iPad (each at low brightness). The only real workaround is to turn your brightness up a tad.

Here's the best description I've found...

+The average brightness of the LED would also be the same if measured electronically. The difference is in the brightness perceived. The human eye has a certain amount of persistence. If exposed to a bright light the eye will "remember" the light for a short period of time. This allows us to view a motion picture or TV screen as a steady image when in fact it is flickering at 24 to 30 times a second. When the LED is flashed on brightly for a short time and then turned off the eye "remembers" the light at the high brightness level. The result is that the perceived brightness of the back light is closer to the high pulsed brightness than to the lower average dc brightness.+
