Video demonstrates the marvel of CRT displays at 380,000 frames per second
We spend a lot of time reading about the differences between display technologies like LCD and OLED, which, like all display technologies, are built to fool our eyes into seeing things that are only simulated, not real, like colors, or realistic movement. But it helps to see it in action.
A video from YouTube channel The Slow Mo Guys (originally reported on by Motherboard) vividly illustrates how CRT, LCD, and OLED displays work by either zooming in very close or by recording in insane frame rates at ultra slow motion.
You'll still find enthusiasts who insist that it's all been downhill since CRT monitors and TVs went sunset for most of the market. While this video doesn't make much of a case for CRT's relative quality, it does show that they were engineering marvels for their time.
