Term of the Moment

Redirected from: roll-up phone
Definition: rollable smartphone
A smartphone with a screen that rolls back into the case like a window shade. Rollable phones become the size of small tablets but take up considerably less room in a pocket or purse than even foldable phones. At CES 2021, TCL and LG demonstrated rollable phones without revealing production dates. Enabling the screen to withstand thousands of rollups are major technical issues to solve. In the meantime, foldable phones have become available (see foldable phone and FOLED).
A Tablet in Your Pen?
Due to the flexibility of OLED displays, a roll-up device has been predicted for years. This mock-up from Universal Display was created more than a decade ago. (Image courtesy of Universal Display Corporation.)
