If you’re waiting to buy a foldable Samsung phone this year, you might need to hold onto your wallet for a little while longer. Samsung Display’s principal engineer, Kim Tae-woong, says the company is currently focused on bezel-free displays. “Because the bezel-free display currently sells well, we still have enough time to develop foldable display,” said Kim at a Display TechSalon event recently. Samsung now believes it will commercialize foldable phones in 2019, despite initially planning to unveil them as early as 2015 or 2016.

Bloomberg reported last year that Samsung was planning to release two phones with bendable displays in 2017, but it’s clear Samsung is still working on perfecting the technology, while reaping the rewards of its bezel-less investments. Samsung initially showed off a bezel-less OLED phone prototype in 2013, before unveiling the Galaxy Note Edge a year later. Samsung hasn’t unveiled a fully flexible phone concept yet, but we’ve seen patents and some display technology demonstrations from rivals. Analysts now believe Samsung will likely unveil a foldable phone once demand for its bezel-less displays slows down.
