  • Patent number: 11755066
    Abstract: A foldable mechanism includes a first movable plate, a second movable plate and a linkage structure. The first movable plate is below and supports an object to be rolled. The second movable plate is spaced apart from the first movable plate along a first direction, is connected to a first end of the object to be rolled and is below and supports the object to be rolled. The linkage structure is movably connected between the first movable plate and the second movable plate. The first movable plate is configured to move along a second direction to drive the linkage structure to fold or unfold, and the linkage structure is configured to drive the second movable plate to move close to or away from the first movable plate along the first direction, so as to switch the object to be rolled between a rolled state and an unrolled state.

  • Patent number: 10964918
    Abstract: A display screen includes: a flexible display panel, and a flexible protective layer covering a light-emitting surface of the flexible display panel, wherein a side surface of the flexible protective layer facing away from the flexible display panel is a light-emitting side surface, and an anti-reflection structure is disposed on the light-emitting side surface. An unevenness feel on a surface of the display screen can be reduced, thereby improving performance of a foldable product such as a foldable terminal.

  • Patent number: 10754217
    Abstract: A display structure and an electronic device having the same are provided. The display structure includes a display screen and a light adjusting component located at a light emitting side of the display screen. An operating state of the light adjusting component comprises a light transmitting state and a polarization state, and the light adjusting component comprises a first region and a second region which are independently controllable. The display screen comprises a plurality of independently controllable pixels. Further, when the first region of the light adjusting component is in the light transmitting state, the pixels that are in the display screen and correspond to the first region are disabled to allow light emitted from the first region to penetrate through the display screen.
