One of the essential problems faced by foldable screens is that the user's repeated opening and closing of the screen may be like opening and closing the book, leaving the creases, which Motorola calls a semi-finished product, leaving permanent deformation marks.
In this regard, Moto proposed a new hinge solution in the patent, adding a heating element and sensors to the hinge of the device. These elements can detect whether the screen is in the unfolded state or the folded state. After that, the heating element will heat the screen. To a predetermined temperature, eliminate creases and restore the screen to a flat level.
According to previous reports, Samsung will release a foldable screen mobile phone in 2019. Samsung has filed several patents on foldable mobile phones, one of which is dedicated to achieving folding without damaging any 'internal components'. But with Moto's Incoming, such a battle of innovation is no longer Samsung's participation alone.
