ELI5: how can smartphones manipulate every single pixel on the screen through a thin ribbon cable with a few electricaö connections?

There isn't a single wire for every pixel on the screen. The graphics system will send information about what is on screen in small batches and the display processor takes this and controls what's actually on screen.

To greatly simplify the process, the graphics system may only send a single pixel at a time but it sends one million of these per frame that needs to be drawn. The information is sent left to right, top to bottom. If you have a really fast camera you can actually watch the screen change, pixel by pixel.
