https://wccftech.com/samsung-extendable-display-smartphone-ces-2020/ > Back in 2016, Samsung demoed a rollable display and various patents about phones with expandable and retractable screens from the company have also been spotted in the past. Well, it looks like the Korean giant has made some headway as apparently it is going to demonstrate the extendable display smartphone technology at a private booth during the CES 2020. > A new report alleges that Samsung is going to show a concept phone with a slide-out display during the trade show. Of course, the wider public will not be shown the new form factor, but the fact that the company has brought it to CES implies it has made significant progress when it comes to development. With a retractable display, users will supposedly be able to extend screen estate by up to 50 percent by pushing a button. Otherwise, the additional screen will remain wrapped up inside the main body of the phone. That’s not the same approach taken by manufacturers for rollable TVs that we have seen in the recent past.
