ELI5:If we can have 5" 1080p displays why can't we have 20" 8k displays?

This is definitely something I've wondered for a while..

No one has demanded such a thing (i.e. mobile devices with this resolution), since 8k content is more of a novelty, "this is the future" thing right now, while 1080p is the mainstream standard.

~~It'd be 10", btw - as the screen is measured diagonally and it's "4 times bigger" as in 4 1080p screens arranged in a rectangle. It'd be perfectly possible to make a 8K 10" tablet by that logic.~~ was thinking about 4K.
