The first file is called “Privacy Films for Curved Displays,” and it has details on a special kind of coating that changes the lighting so that the viewing angle is limited.

“Displays with Adjustable Angles of View” is the title of the second patent. It describes technology that lets the owner of the gadget change the angle at which light spreads.
