Modern display technology is pretty amazing. It’s come such a long way since its early days of black & white. And since shifting from the Cathode Ray Tube (CRT) TVs of the 90s to flat panel Plasma, LCD and OLED technology, they’ve come even further. But how do they actually draw that image on the screen and make it look like things are moving across the screen?
Obviously, pixels themselves do not move. It’s all an illusion. Still images played back rapidly, and our brain’s persistence of vision takes care of the rest. But you don’t really see exactly what’s going on until it’s filmed at over 380,000 frames per second and slowed down. Which is exactly what Gavin and Dan at the Slow Mo Guys have done.
