Why does it matter? A screen’s response time is a measure of how fast its pixels can complete one full picture ‘cycle’, so that they’re ready to play a part in the next frame of the picture.
Screens with long response times can have problems refreshing every element in their pictures rapidly enough to keep up with fast motion, resulting in moving objects looking blurred and smeared.
Myth Flat TVs have trouble retaining resolution when displaying fast moving images.
Fact Plasma TVs can present moving objects without loss of crispness or detail.Plasma technology needs only one impulse per pixel to produce an image therefore its response time is almost instantaneous.
LCD technology requires pixels to go from active – to inactive -and back to active again, to achieve a single response cycle; their response time can measure anywhere between 4 milliseconds to and 25 milliseconds. Even the fastest LCD screens can suffer with some degree of movement blurring.

Example With an LCD screen it would be difficult for you to clearly see a tennis ball hitting the tennis court after being served. The response rate would not be fast enough to keep up with the trajectory of the ball. On a plasma screen you can enjoy every moment of fast action like sports and film.
