Intel and Samsung Display are developing “slidable” PCs. Samsung Display CEO JS Choi made an appearance on stage during today’s Intel Innovation speech to demonstrate a prototype PC that transforms from a 13-inch tablet into a 17-inch display.

The first 17-inch slidable display for PCs is being announced, according to Choi. “This gadget will meet a variety of demands for both mobility and a bigger screen.” For its flexible PC screens, Samsung Display has decided to use a sliding (rather than a folding) technology, and Choi seemed to imply that “foldable is gone” on PCs for the time being.

Prior to Microsoft abandoning its plans for Windows 10X on foldables, Intel had been experimenting with novel PC form factors for years and was initially getting ready for a dual-screen and foldable future. It’s still unclear how Intel will make slidable PCs a reality, but these novel form factors urgently require the software and apps to shine.

With a flexible display and a sliding mechanism, the prototype gadget that Samsung Display and Intel unveiled today basically transforms a 13-inch tablet into a 17-inch monitor. On one display, Intel was keen to show off its new Unison software, which seeks to link PCs powered by Intel to smartphones, including iPhones.

The slidable PC itself is just a concept for now, and there’s no word from Intel or Samsung Display on when it will become a reality.
