LG's Rollable Smartphone Concept: The Dream Lives On with New Display Patent
LG, once known for its innovative smartphone designs, has filed a patent for a new magnetic system to keep rollable OLED displays smooth and wrinkle-free. This technology could potentially be used in future rollable smartphones, although LG has not made any official announcements about reviving its smartphone efforts. The patent describes a magnetic sheet added to the back of the display and magnets built into the device's frame to help smooth out wrinkles when the screen is extended or retracted.
