There are a lot of important thing you should considered before you purchase an LCD TV. One of those important things is the response time. Some people might not understand the meaning of response time in LCD TV and ignore it, which actually wrong because its existence is very important.

The response time is the speed of one pixel in screen change from one color to another. It is quite similar like the shutter in digital camera. When the response is fast, the picture taken is clear and appears in good quality. In the other hand, if the speed is low, the pictures occur blurred and appear in low quality. Even though the difference of response is count on milliseconds, but the fact shows that our naked eyes able to catch picture in 14miliseconds. If the available picture unable to exceed the speed of our naked eye, the picture will looks blur and hardly to enjoy.
