ELI5: If phones can have 5-inch, 1080p amoled touchscreen displays, why can't a tv just use a series of those displays?

I was using my phone at night when I realized my phone has a better resolution than my 32" 720p tv. Besides the fact that I am a lot closer to my phone's screen than my tv's, why can't we have tvs that have the same type of screen, albeit a lot more pixels?

* Making a large television with the same pixel density would be extremely expensive. It wouldn't make economical sense to do so. 

* There's not as much benefit to high pixel density displays for televisions because you're at a greater distance from the screen. 

* It wouldn't make sense to have such a high resolution since there's little to no content for consumers above 1080p. We're just starting to have some 4K content available to the consumer market, so for now, there's no real reason to go above that. 

* It's difficult to devices to drive super high resolution displays, due to the sheer amount of data required to do so. A lot of cable standards don't support anything above 1080p or 4K.
