We've seen smartphones, tablets, and laptops with foldable displays in recent years. Now a company called Aura Displays is bringing foldability to another product category: portable monitors. The Aura Single Flex Pro (Gen 1) is a 13.3 inch OLED display that you can fold in half so that it takes up less space in your bag. Or you can bend it in the middle to create a sort of pseudo-laptop experience with one part of the screen facing upward while the other faces forward or hold it in your hands like a book with the fold acting like the crease.

Want to give your laptop a little extra screen space when you're on the go? There hundreds of portable monitors available that can double your screen space with typical prices ranging from $50 to $200. And if you want to take things to the next level, several companies have launched slightly higher-priced dual-screen portable displays that turn a laptop into a triple-screen beast.
