Once upon a time, ok just two or three years ago, Korean rivals Samsung and LG were seemingly involved in a rat race for foldable, if not flexible, devices. The two have recently become silent, with both having achieved some amount of success as far as flexible screens go. Samsung, however, has definitely not given up on the dream just yet. A new batch of patents filed at the USPTO hints just as much, with three new designs that could pique one's curiosity. At least as far as ideas go.
