Each of these lenses is tiny. LG demonstrated just how small they are when talking about one of its latest tellies. Each OLED pixel can fit 5000 of these micro lenses. That means that a 77-inch telly will cram in an impressive 42.4 billion of these lenses. The entire extra layer is pretty sophisticated, and involves a different manufacturing process.

If they can fit 5000 lenses into each pixel on every TV, there's no limit to what tiny things they can build.
