    Abstract: Disclosed is a display substrate including a base substrate, and a power signal line and an electrode block that are disposed on the base substrate, the electrode block covering at least one side of the power signal line. The base substrate has an encapsulation area. An orthographic projection of the power signal line on the base substrate extends out of the encapsulation area from an interior of the encapsulation area, and an orthographic projection of the electrode block on the base substrate overlaps the encapsulation area. By covering a side of the power signal line in the encapsulation area with the electrode block, the present disclosure can prevent the side of the power signal line covered with the electrode block from being drill-etched, thereby improving the encapsulation reliability of the display substrate.

  • Patent number: 10492311
    Abstract: The present disclosure provides a flexible display device, wherein there is a flexible support structure fixed on a surface of the flexible display module, which is used to disperse stress. During use of the flexible display device, the flexible support structure can be used to disperse the point force or linear force that the flexible display device is subject to when being bent into even planar force. Besides, the flexible support structure can reduce the stress exerted on the flexible display module, avoiding delamination among the film layers caused by local stress concentration on the flexible display module. In addition, given the same thickness of the flexible display module, the flexible display device can be bent to a smaller bending radius.
