  • Patent number: 11908870
    Abstract: A TFT array substrate includes a substrate layer and a metal layer disposed on the substrate layer. The metal layer includes a metal layer bridging structure having a first metal layer and a bridging second metal layer. An insulating layer is disposed between the first metal layer and the bridging second metal layer. The first metal layer includes two segments of a first segment and a second segment of the first metal layer, which are disposed at intervals. The first segment and the second segment of the first metal layer are connected by the bridging second metal layer. The TFT array substrate has a bending region adopting a new metal layer routing structure, and routing of the first metal layer in the bending region is prevented from passing through two holes of a filling layer (OILD), thereby effectively reducing the risk of subsequent breakage due to over-etching.

  • Publication number: 20220199719
    Abstract: The disclosure provides a thin film transistor (TFT) array substrate provided with a display area and a bending area, including a substrate layer and a functional layer disposed on the substrate layer, wherein the functional layer includes a plurality of insulating layers and a plurality of metal layers. In the bending area, the metal layers include a first metal layer, a second metal layer, and a second gate layer. The first metal layer is disposed on a side end of a filling layer and connects to the second gate layer by a through hole. The second metal layer is disposed on an insulating layer on an outer side of the first metal layer.

  • Patent number: 11355574
    Abstract: The present invention provides a display panel and a manufacturing method thereof. The display panel includes a flexible substrate, a buffer layer, a combination insulation layer, recess, an organic insulation layer, and a first wire changing layer. The first wire changing layer is disposed on an upper surface of the organic insulation layer and extends to the combination insulation layer. The present invention removes a through hole in a conventional organic insulation layer, on one hand mitigates the issue of broken lines in the first wire changing layer, and on the other hand mitigates the issue of shorting of adjacent two of wires in the first wire changing layer because of square waveform, sawtooth waveform, triangular waveform, and sinusoidal waveform of an edge line on a side of the first wire changing layer such that stability of the display panel is improved.
