Samsung patents sliding mechanism for rollable screens

This filing describes a device with a screen that rolls out from a compact body when a second housing slides open. It uses a guide assembly with specific slits to keep the rolling screen and its support bars aligned during movement.

Why it mattersIt offers a potential way to create larger screens in smaller devices without using fragile folding hinges.
