Lapscreen is a 12.5-inch USB-C Monitor that uses a single cable which connects to your computer, phone or tablet. Video and power can be connected through this single cable as well. There is also an HDMI port if you prefer it over the USB Type-C.
Measuring at 11.1 inches x 8.3 inches with a weight of 400 grams, the screen is roughly the size of a sheet of paper, with a 4 mm thick display portion. You get the advantage of an ultra-thin, ultralight extra display that you can carry with you in your folder or laptop case if there happens to be a need of some extra space.
