Here's how a TV works in super slow motion

[Shawn Knight]

The world is a much more compelling place when slowed down. As the crew behind The Slow Mo Guys channel on YouTube has demonstrated over the years, it’s often ordinary tasks we do every day – like snapping a photo or watching television – that are the most captivating when viewed in slow motion.

As you may know, what you watch on TV is simply a series of still images – hence the term “motion picture” – that refresh fast enough to trick our brains into thinking we are seeing moving objects (think of a flip book). Knowing how the concept works and seeing it in action, however, are two very different things.

The Slow Mo Guys in their latest video point their high-speed cameras at various types of television sets to see what’s really happening. The intricacies of how it all works are fascinating, especially seeing Mario’s mustache drawn in less than 1/380,000^th of a second.

The video also delves into the technological differences between CRT, LCD and OLED displays and looks at how individual pixels are used to display colors.

Pretty impresive

That was interesting

I always "knew" how these types of TVs worked, but to see it broken down like this and to actually see how the pixels respond in each display type is truly awesome.

Kind of old news since the first "motion" picture was generated on a turning wheel with a series of still images ..... prior to 1900 ........ but still informative for those that missed that history lesson .... by the way, if your really interested you can see that device at the George Eastman House in Buffalo NY.

Very interesting.

Say, is it true that CRT are still superior when it comes to moving images? Ever since I have become aware of motion blur, refresh time, gtg and so on, its been driving me nuts.

So nuts in fact that I got myself a Samsung U28H750 which uses a TN panel. It does a pretty good job I guess. Much better than my previous screen. However on its fastest setting which I think is the advertised 1ms it suffers from severe ghosting which again totally destroys the viewing experience.

So uhm if you could focus on that whole madness next I'd appreciate it.

As far as image reproduction goes, *nothing* beats CRT. The main issue with CRT is the fact the monitors are huge, but every other display tech, from LCD to LED to OLED is technically inferior to CRT when it comes to displaying non-static images.

I'm surprised (if I understood correctly) that even OLED screens *still* rely on separate Red, Blue & Green diodes packed close together.

I was under the impression each pixel was a single diode capable to emitting any color (like color-changing LED bulbs.) You'd get all the benefits of an OLED screen with 3x the resolution.

Did anyone ever use anything like that?
