  • Patent number: 12158676
    Abstract: The present application provides an array substrate and a display device. By placing a first shielding electrode between the data line and the common electrode arranged opposite to each other, the first shielding electrode is connected to a DC voltage signal, so that a data voltage signal of the data line does not affect a signal of the common electrode. This prevents coupling capacitance between the common electrode and the data line, and prevents poor display quality like screen flickering.
