  • Patent number: 10228594
    Abstract: The present disclosure discloses an array substrate, a display panel and a display device. The array substrate includes gate regions, gate lines, data lines, pixel electrodes and common electrode lines. The common electrode lines and the gate lines have the same extension direction, the pixel electrodes are located in regions defined by adjacent gate lines and adjacent data lines, the gate lines traverse the gate regions in the extension direction that are located in the same row as the gate lines, and the pixel electrodes have a gap from the gate lines at ends thereof closer to the gate lines. As such, a portion of the gate region that extends to the pixel region has a reduced area and hence a reduced edge length. This way, during the cleaning of the active layer after formation, less active layer metal may remain at the edges of the gate region. Thereby, the array substrate fabrication process is improved, and a product yield rate of the array substrate is increased.

  • Patent number: 9865625
    Abstract: The present disclosure provides an array substrate and a method of manufacturing the same, and a display device. TA connecting portion is provided within the overlapping region between the first signal line and the second signal line, is electrically conductive and directly contacts the second signal line. Thus, even when the upper second signal line is broken due to the large step difference within the overlapping region between the first signal line and the second signal line, the connecting portion electrically connected with the broken second signal line can still electrically connect and conduct the broken second signal line, thereby avoiding transmission of signal from being adversely affected by the broken signal line within the overlapping region.

  • Patent number: 9716112
    Abstract: The present disclosure relates to the field of display technology, and provides an array substrate, its manufacturing method and a display device. A signal line on the array substrate includes at least two conductive layers electrically connected to each other. When one of the conductive layers is broken, a signal may be transmitted through the other conductive layer(s). As a result, it is able to improve the reliability of the electrical connection of the signal line, thereby to improve the yield of the display device. Further, the plurality of conductive layers of the signal line is formed simultaneously in an existing process for manufacturing the conductive layer patterns for the array substrate, so it is unnecessary to form the signal line separately, and thereby the manufacturing process is simplified.
