  • Publication number: 20220066521
    Abstract: The present disclosure provides a bend-resistant wire, a preparation method therefor and a flexible display panel, and relates to the field of display technologies. The bend-resistant wire is formed on a side surface of a flexible substrate of a flexible display panel that is located in a fan-out region, the bend-resistant wire includes a conductive layer, the conductive layer has hollow parts formed corresponding to a bent region of the flexible substrate, and an area of each of the hollow parts in the bent region is positively correlated with a curvature of the corresponding bent region. An objective of the present disclosure is to provide the bend-resistant wire, the preparation method therefor and the flexible display panel, which can reduce a risk that a fan-out wire of the flexible display panel breaks when the flexible display panel is bent.

  • Publication number: 20220066522
    Abstract: Embodiments of the present disclosure provide a flexible display panel and a display apparatus, and relate to the field of flexible display technologies. The flexible display panel includes a bent region, the bent region includes a trace layer, and the trace layer is provided with a wire. The wire includes a first bent part and a second bent part adjacent to the first bent part in an extension direction of a bending parallel line, and the second bent part and the first bent part are located on different bending parallel lines, where the bending parallel lines are parallel to a bending axis of the bent region. The flexible display panel can improve bending resistance of the wire, reduce a risk of wire fracture during bending of the bent region, ensure a signal transmission effect, and effectively alleviate the problem of poor display.

  • Publication number: 20210287612
    Abstract: A display device includes a pixel array including M rows of pixel units, M scanning lines, a first drive module, and a second drive module. An Nth scanning line is connected to the pixel units in an Nth row and the pixel units (11) in an (N+2)th row. One of the first drive module and the second drive module is connected to the scanning line connected to the pixel units in an odd row and is configured to supply, via the scanning line, a scanning signal and a reset signal to the pixel units in the odd row, and the other of the drive modules is connected to the scanning line connected to the pixel units in an even row and is configured to supply, via the scanning line, a scanning signal and a reset signal to the pixel units in the even row.
