I decided to buy a new TV for my bedroom to replace the CCFL-based LCD TV that I had there. I didn't want to get an enormous plasma TV so I bought a 32-inch LED TV. I even read somewhere that this TV has a dynamic contrast ratio of 3000000:1-they didn't say what its static contrast ratio is. My old LCD TV had a static contrast ratio of 4000:1, which is pretty good. The new TV is Samsung by the way. This new TV has full-array LEDs, it doesn't have local dimming and it is not edge-lit.
But now I am wondering. I read in Wikipedia that when dynamic contrast is turned on on an LCD, which is an added feature of the TV (LEDs are still LCD technology), when there is even a small super bright object on the TV screen the contrast is affected. So, I guess, even a 3000000:1 dynamic contrast ratio goes out the window. Also, as these new LED TVs have an extremely bright picture, I don't know what happens to the static contrast ratio (which is actually more important).
Of course, LED TVs with local dimming really do have great contrast. But the manufacturers have decided to cheap out and make the other LEDs because local dimming is expensive.
