Lee Min-Cheol, Samsung Electronic's PC Marketing VP says that Samsung is collaborating with "display makers" (Samsung Display? or an error in the quote?) to develop OLED laptops with foldable displays. Samsung says that it aims to bring "new value and user experience" and not just create a laptop and can simply fold in and out.
Samsung will hopefully release its first foldable smartphone device by the end of 2018 or in early 2019, but apparently the company is already thinking about other form factors. Earlier this month a report from Korea suggested that LG Display is collaborating with Lenovo to develop a 13" foldable tablet, with aims to start panel production in H2 2019.
