I *believe* it enables the CABC stuff.
From natisbad.org:

If you wonder, CABC stands for Content Adaptive Backlight Control. It allows reducing backlight or brightness levels depending on the image being shown to save power. For instance, if the image contains only dark pixels, the brightness of the backlight can be reduced. This will naturally boost the pixel value.

You can manually force a change to the CABC state through MCE's D-Bus interface: http://maemo.org/api_refs/5.0/5.0-fi...759e0241b19bd8
