How do LED monitors make the connections between each LED

From my understanding, LED monitors turn each pixel on sequentially at such a high speed that the human eye can't observe it, but how does it make the necessary connections? For example, for a monitor made with a single color of LED across a standard HD resolution (say 1940 x 1080) there would have to be 3020 connections assuming its built in a grid.

I'm assuming I'm missing something.
