  • Patent number: 11801657
    Abstract: A flexible display module and a manufacturing method thereof are provided. The flexible display module includes a substrate, a second glue layer, and a display panel disposed in a stack. Wherein, the display panel includes a bending area, and a first groove is defined in a third area of the substrate corresponding to the bending area and filled with a first glue layer. More deformation can be provided and bending stresses can be reduced by the first glue layer and the second glue layer, thereby improving bending resistance of the flexible display module.

  • Publication number: 20210325936
    Abstract: A bending hinge for a flexible panel and a terminal are provided. The bending hinge for a flexible panel defines a flat state and a bending state and includes a support sheet and a component chain in a zigzag shape. The component chain includes a plurality of components. A lateral section of each of the components defines a support surface. When the bending hinge is in the flat state, a spatial gap exists between the support surfaces of the lateral sections of the adjacent components. When the bending hinge is in the bending state, at least part of surfaces between the support surfaces of the lateral sections of the adjacent components contact each other under an external force.

  • Patent number: 11050030
    Abstract: An organic light-emitting diode (OLED) display screen and an OLED display device are provided. The OLED display screen has a first display region, a second display region, and a folded display region. A bonding region is disposed on a side edge of the second display region away from the folded display region. Only part of a first backplate disposed on the second display region close to the bonding region is retained and replaced with a buffer layer to ensure stability of a shape of the folded display region and prevent wave warping.
