US Patent 11792945 Rollable display device

A rollable display device includes a rollable screen, including a non-display part and a display part; and a telescopic mechanism. The rollable screen is laid surrounding the telescopic mechanism. The display part includes a fixed display portion and a rollable display portion. The fixed display portion is fixed on a first plane, and the non-display part is connected to the side of the rollable display portion away from the fixed display portion. The side of the non-display part away from the display part is connected to the telescopic mechanism. In a process of extension or retraction, the telescopic mechanism is configured to drive the rollable display portion to slide and bend. In the retracted state, the orthogonal projection of the rollable display portion at least partially overlaps with the fixed display portion. In the extended state, the orthogonal projection of the rollable display portion unoverlaps with the fixed display portion.
