In case you didn’t know, when you’re watching TV, you’re not really seeing an actual moving image, but instead, a series of still images flash very quickly and are projected to create the illusion of the moving image in video form.
Science and technology entertainment web series The Slow Mo Guys, further investigates this cool process and reveals exactly what you are looking at when you stare at the TV in extremely slow motion.
Equipped with high-speed Phantom Flex and Phantom V2511 cameras that can record between 1600 and 380,000 frames per second, the duo Gavin Free and Daniel Charles Gruchy, record a TV screen and dissect its refresh rate, as they are able to see that the screen refreshes not only from top to bottom, but also from left to right, line by line. Each pixel is essentially updated one at a time, and very quickly that makes it look like the screen refreshes all at once to the naked eye.
