rollable display

A rollable display is a digital screen technology that can be rolled up like a newspaper.

At CES 2016, LG demonstrated an 18-inch rollable screen based on a FOLED (organic light-emitting diode) display. According to LG, the substrate for the display is a high molecular substance-based polyimide film. The display material is less than a millimeter thick and has a 1200 by 810 resolution.

Although some are referring to the screens as "foldable," the display cannot actually be folded because the complications of circuitry would result in dead pixels. However, the company expects to offer foldable displays in the future. At the 2016 event, the company displayed an array of flexible, bendable, curved and transparent displays for different applications.

The prototype was demonstrated by an LG rep wearing special gloves. Conference-goers could handle a non-working protype that gave them an idea of the display material's potential.
