  • Patent number: 10861881
    Abstract: The array substrate taught by the present invention have dummy ITO lines on the fanout lines configured as multiple segments separated at intervals so that, when two neighboring dummy ITO lines are short-circuited, the place of short circuit is limited to a segment of the neighboring dummy ITO lines. Coupling capacitance is limited to that between the segments and fanout lines. Compared to prior arts where coupling capacitance occurs between neighboring dummy ITO lines and fanout lines, the present invention has much smaller coupling capacitance, thereby reducing the impact of coupling capacitance to signal transmission on the fanout lines, avoiding the occurrence of light lines on the display panel, and enhancing the display effect of the display panel.
