VIDEO: WATCH A TV-SCREEN REFRESH IN SLOW-MOTION

Date: 2018-01-21



If you are reading this, then you’ve seen a screen with your eyes, obviously! 

But, have you REALLY seen it though? Like real, proper "seen" it? Don’t worry,Gav is here to help you out.

This episode from The Slow Mo Guys is called 'How a TV Works in Slow Motion', and it gives us an in-depth look at how a television works with help from his slow-motion equipment.

Slow motion segments were filmed with the Phantom Flex and Phantom V2511 high-speed cameras between 1,600 and 380,000fps. While filming a TV screen with a regular camera, it’s easy to see the screen refresh, simply because the TV’s refresh rate and the camera’s capture rate don’t sync up perfectly.

But with a high-speed camera, it’s possible to slow down that refresh rate and see it happen line by line, literally. With an incredibly fast camera, it’s possible to see that the screen refreshes not only from top to bottom but also from left to right.

Each pixel is updated one at a time, so quickly that it looks like the screen refreshes all at once to the naked eye. So next time you’re watching a video on your TV, remember it’s just moving too fast for you to see what’s really going on.

Have a look at the slow motion video below.
