Response time
Response time or latency describes the time an LCD takes to change from full black (active liquid crystals) to full white (inactive) and back to black again. This time is measured in milliseconds and a typical response time falls within 8 to 16 ms. The way an LCD computer monitor or television works is by activating and deactivating pixels, so unlike CRT and Plasma displays which use phosphors exited by electrons (equivalent response time of about 1ms), the liquid crystals in the LCD display take a considerably longer time to emit light corresponding to information from the video source. This slower response time created ghosting during the earlier years of commercial LCD display production. LCD screens with a large response time value are frequently unable to properly display fast-paced video games, so a blur or smearing effect is seen during game play. However, using a large group of Response Time Compensation technologies many manufacturers have been able to reduce response times to values that approach that of a CRT display.
