  • Patent number: 11227514
    Abstract: The present disclosure provides a cover, a manufacturing method of the cover, and a display device. The cover includes a planar region and a bending region. The cover also includes a substrate, a flexible layer, and a hard layer disposed in a stack. A thickness of the substrate in the planar region is greater than a thickness of the substrate in the bending region. Decreasing the thickness of the substrate in the bending region can improve bendability of the cover, and the hard layer can ensure hardness of the planar region at a same time. Combination of the two can make the cover achieve high hardness and good bendability at the same time.

  • Publication number: 20210116968
    Abstract: A flexible protective cover for attaching to a display panel, the flexible protective cover includes at least two hard coating layers and a transparent layer disposed between two adjacent hard coating layers. Since a modulus of the hard coating layers is greater than a modulus of the transparent layer, a hardness of the flexible protective cover can be significantly increased. It has been verified by simulation calculation that the flexible protective cover of the present disclosure has a hardness increase of 8% while maintaining same flexibility and bending resistance, as compared with the conventional flexible cover.
