LCD TVs and Response Time

Response time is basically the amount of time it takes for a liquid crystal cell to go from active (black) to inactive (white) and back to active (black) again. It is measured in milliseconds or (ms). Lower numbers mean faster transitions (eg. 4 ms is faster than 8 ms) and therefore less visible image artifacts.

LCD TV manufacturers have been steadily improving response times as the demand for fast moving full motion video has increased. A good response time starts at around 10 ms. Some newer model LCD TVs have response times as fast as 4 ms.
