Rollable OLEDs

Rollable OLED displays are exciting - as these displays can enable new device form factors - such as TVs that roll up into a small cylinder or a tablet-sized device that can roll-up into a pen.

Rollable OLED TVs

In early 2019, LG launched the world's first rollable OLED device - a TV that rolls into its base. The 65" Signature OLED TV R has three viewing options - full view, line view and zero view. This is a radical new TV form factor, which will be probably be highly expensive when it starts shipping during 2019 (we still do not know the exact release date and price). The TV offers the highest image quality - enabled by OLED technology.

Rollable mobile devices

While LG is leading the race to rollable OLED TVs, many display makers are developing smaller rollable OLED displays for mobile devices. Back in 2016, for example Samsung Display demonstrated a beautiful rollable OLED, a 5.7" display that featured a Full-HD resolution (386 PPI) and a curvature radius of 10 mm. The whole display is 0.3 mm thick and weighs 5 grams. We do not know yet when SDC plans to commercialize such a display (the company is currently focused on developing its foldable OLEDs).
