Do you remember how long foldable OLED displays had to hang around technical convention halls before they finally started appearing in products? Well say hello to the screen that your phone from 2030 might have. Okay, not exactly this one.

Samsung yesterday unveiled a 13-inch expandable OLED display at the Global Tech Korea conference. The demos, captured in a clip below, show a potential use case for augmenting images of moving fluid.

This isn’t the first expandable display we’ve seen from Samsung – it debuted with a 9.1 “panel and a 5% surface deviation tolerance in 2017, according to ETnews – but it’s the more expandable to date although we have not received any new stats.

Meanwhile, LG says it continues to move forward with curved and rollable OLED technologies, but with its closed smartphone division and roll-up phone concept shelved, we wonder where we’ll see its. Mark.

It seems that with the physics we’re dealing with right now, bigger will be the best way forward when we get to first-gen products, but don’t count the pocket form factors just yet: Samsung has planned a phone with a screen expandable for at least 2 years.
