A Faster Refresh for LCDs - 120Hz


Motion blur has long been the Achilles heel of LCD TVs. A new refresh rate hopes to mend that wound and offer better processing potential.

A refresh rate refers to the speed at which a display is redrawn every second, and it is measured in hertz. Refresh rates have become an issue for LCD TVs, which lag behind plasma and DLP in their ability to reproduce fast motion without blurring.



The refresh rate for a normal LCD TV is 60 Hz, which means 60 frames per second. That's pretty fast, but not fast enough for some action, which still causes a blur. LCDs with the fastest response times [like 5 milliseconds] still have perceived motion blur because of the sample-and-hold drive techniques [of LCD], says Patrick Dunn, director of display technology at THX. However, moving to 120 Hz cuts the wait time in half between frames, because you are driving it twice as fast.
