Contrast ratio is the difference between white and black on a given display. The higher the number means there is a larger difference between white and black and will typically look better. See here for a better explanation: http://en.wikipedia.org/wiki/Contrast_ratio
1500:1 is the better contrast ratio
The contrast between true black and true white on the screen. The higher the contrast ratio the better. 1000:1 is better than 700:1. An advertised dynamic contrast ration is much higher than the contrast ratio, but not a true measurement of contrast. Dynamic contrast adjusts the backlighting to give the effect of an overall brighter or darker image.
A 12,000:1 contrast ratio is good, but a 50,000:1 would be better.
Generally the higher the first number, the better.

Contrast ratio isn't standardized, so manufacturers can fudge the numbers. Consider, however, a contrast ratio over 600.
The Higher the Better. You will see more detail in the darker part of the picture.
