I think you'll find this interesting too, part of something I read. Enjoy..
"---The Motorola Droid provides the most accurate colors. It represented 98% of the standard color gamut, as opposed to the iPhone's 63%. The Nexus One showed 141% of the standard gamut, which means colors end up looking punchy and oversaturated rather than realistic. The CLIQ came very close to the Droid, at 103%.
---The Google Nexus One has the deepest blacks and best contrast. Because of its AMOLED screen, blacks are very close to true black. On the Droid, "black" still emitted 0.26 candelas per square meter, and the CLIQ had a statistically similar 0.21 candelas per square meter of output; the iPhone's washed-out blacks emit 2.5 candelas per square meter.
---On the other hand, the iPhone's screen is really bright, which makes it easier to read outdoors. It emitted 444 candelas per square meter when displaying white, as opposed to the Droid's 391, the Nexus One's 229 and the Cliq's 224.
So who has the best screen? We'd vote for the Motorola Droid. While the iPhone's screen is brightest and the Nexus One's colors pop, the Droid has the best balance of brightness and accurate colors on its 848x480 LCD panel."
