  • Patent number: 11644600
    Abstract: Proposed is a flexible cover window including a window substrate and an elastic buffer layer having a single-layer structure or a multi-layer structure. The elastic buffer layer is provided on the rear surface of the window substrate to absorb deformation occurring in a folding part. The flexible cover window is a glass-based cover window for protecting a flexible display that is foldable, rollable, slidable, or stretchable. In addition, the flexible cover window has an elastic buffer layer on the rear surface of the window substrate to reduce the difference in elongation between the window substrate and a display panel so that delamination or buckling due to micro-deformation at the folding part thereof can be prevented. Therefore, the life span of the flexible cover window is prolonged and distortion of an image on the screen at the folding part can be prevented.

  • Patent number: 11628715
    Abstract: A shift control method for an automated manual transmission (AMT) of a vehicle includes: when a shift operation is started, a torque of the second motor is increased so that a change in an output torque of the output shaft due to a change in a torque of the first motor is minimized while the torque of the first motor is being decreased. According to the shift control method, the increased torque of the second motor is maintained to be constant while controlling transmission release, speed synchronization, and transmission coupling. After the control over the transmission coupling is completed, the torque of the second motor is controlled so that the output torque of the output shaft follows a predetermined target torque while the torque of the first motor is controlled to be increased.
