The human eye perceives colors relative to their surroundings, so a black pixel next to a white pixel will look blacker. You can exploit this effect to enhance the perceived contrast ratio. How well this works in practice varies.

This, and in general setting LED brightness to minimum necessary to get target brightness with fully open LCD, taking into account interaction of nearby LEDs (light from one LED spreads to adjacent cells, thus you could minimize brightness of boundary LEDs even farther).
