The images are held long enough that your brain assumes anything in motion is going to continue being in motion… but it isn't. However, your brain is working fast enough that it's expecting to see motion during those hold times. You don't see still images, you see fluid motion. Sixty still images every second is fast enough to exceed your brain's flicker fusion threshold.

Your brain on LCD TV motion: The blur is in your head

Some TVs have faster refresh rates, and in some countries TV refresh every one-fiftieth of a second, but the process is the same.

Then the screen refreshes and a new image is held there for another one-sixtieth of a second. With most TVs this means that for a full one-sixtieth of a second, the image is stationary on screen. LCDs - and modern OLED TVs - configure their pixels to show an image and then hold that image until the screen refreshes. These days most LCDs are able to change their states fast enough that motion blur is caused by something else: ' sample and hold.' In the early days of flat TVs and displays, the culprit was often the slow speed of the liquid crystal elements that create an image on LCD TV. Note how the lower 1.5 dolphins are softer than the others. There's also blur caused by the TV itself, which, to an extent, you - actually, your TV - can do something about.Ī still photo edited to mimic motion blur. Some of this can be attributed to the lower frame rate of movies and most TV shows, which can result in a blur caused by the camera. One second you're seeing every eyelash and wrinkle, the next it's a blurry mess. I always notice it when there's a closeup of a face, and then the person turns away. This can be a single object, like a ball or car, or the entire screen, as when the camera pans across a landscape. Motion blur is when anything on-screen blurs, becoming fuzzy and less distinct, when it moves.
