In cybersecurity and technology, a 'crease' refers to the visible or tactile line that appears on foldable device screens at the point where the display bends, typically due to the hinge mechanism. This crease is a result of the repeated folding and unfolding of the screen, which can cause slight distortions or changes in the display’s surface. While primarily a hardware characteristic, creases can sometimes impact the usability or longevity of foldable devices. Manufacturers continually work to minimize crease visibility and its effects, as it may influence user experience and device durability. The term is most commonly associated with modern foldable smartphones, tablets, and laptops.
