Response time refers to time taken by a pixel in a LCD TV to change from active (black) to inactive (white) and vice versa and this change usually takes place in fractions of a second, so it is measured in milliseconds.
A response time between 8 to 16 ms is normal while the older televisions used to have higher response time than 16 ms. High response times can be unpleasant for the viewers as they would produce blurs when moving objects are displayed on the screen. Usually the lower response times ensure that pictures are free from such kind of image artifacts. Similarly, the display systems with a high response time value are often unsuitable for fast paced video games, action-packed scenes, sports etc.
Do LCD screens have high response time?
Due to its display technology, the older LCD TVs had problems with smearing or ghosting. However, current LCD TV models have improved response time, so the artifacts are rarely seen. The latest LCD TVs make use of the innovative technologies like overdrive technology or Response time Compensation that significantly reduces gray transition.
As a result, there are many high- end LCD TVs which have a response time of 6 milliseconds and give satisfactory results when playing action-packed games or movies or software which need quicker refresh rate.
As a thumb of rule, the screen size and the quality of the LCD TV are the deciding factors when you purchase a LCD TV.Although response time of a LCD TV has become a non-issue in recent times, still it is a good idea to spend some time reading LCD reviews which provide you with the specification of the LCD TVs. While the high-rated LCD makers often provide you with realistic specs, it is always wise to check them by viewing some action-packed movies to ensure that the LCD renders pictures without motion lags.
