What is response time and refresh rate when talking about TV's?

Question

some commercial says 2 milisecond response time

Answer 1

Response time and refresh rate are essentially the same thing... there is either 60hz or 120hz, it just means how fast your tv reproduces color and picture. For example, if your watching something move quickly across the screen, the picture will be blurred from the quick movement, a higher refresh rate makes fast moving pictures become less blurred and more defined.

Answer 2

I have no clue what BB is teaching their sales associates but refresh rates and response times are NOT the same thing.

Refresh rates refer to the number of times per second a TV screen is updated with a new image. The typical refresh rate for US TVs has been 60 times per second (60 Hz). LCD TVs suffer from motion blur. One technique used to help reduce motion blur is to increase the refresh rate to 120 times per second (120 Hz).

Response time refers to the time that it takes to change the state of on an individual LCD pixel. Response times can specify the time it takes a pixel to change state from black-to-white-to-black or from one gray level to the next gray level. There is no real industry standard on how or what to report as response time, so take this number with a grain of salt (unless you know the measurement specifies of this value). Typical LCD repose times had been around 8 ms. Many of the newer LCD TVs now incorporate faster 4 ms pixels. Response times also affect motion blur and jitter.
