screen definition in pixels
|
Howard Traxler
Now ,the new screen definition is UHD (ultra high definition) which means there are 3840 x 2160 = 8,294,400 pixels in the screen. It makes me wonder:
1. How big is a pixel? There must be different sizes, as they can put the same number on a 14-inch screen as onn a 49-inch screen. 2. How are those pixels fastened in there? Some special kind of glue that they hope won't let loose, I suppose? 3. How tiny is the tool (hence the hands) that install all those pixels? Mighty small fingers and (probably) treezers? 4. What material is a pixel made of? Is it just a glob of Mystery Magic Material (MMM from the Three M company) encapsulated in a clear plastic? That would be small. Inquiring minds, ya know. Ideas?

Interesting questions! In short: 1) Yes they vary as you say - the higher definition your screen, the smaller each pixel and the more crammed into the same space. This makes for a smoother looking image for those with the sight to see such things the closer in they look. Here's an article with a bit more info: https://www.techopedia.com/definition/24012/pixel 2, 3, 4) Good questions and TBH not something I'd looked much into, but here's another article I found on it: https://www.forbes.com/sites/willyshih/2018/05/15/how-did-they-make-my-big-screen-tv/?sh=1736909b1003 Kind regards Quentin.
