  • Patent number: 12198651
    Abstract: A pixel circuit of the present invention includes a thin-film transistor, a first scan line, a second scan line, and a data line. The first scan line is arranged along a first direction. The first scan line is electrically connected to the thin-film transistor. The second scan line is arranged along a second direction. The second scan line is electrically connected to the first scan line. The second direction is perpendicular to the first direction. The data line is arranged along the second direction. The data line is electrically connected to the thin-film transistor. The pixel circuit also includes an auxiliary scan line. The auxiliary scan line is arranged along the second direction. Two ends of the auxiliary scan line are electrically connected to the second scan line.

  • Patent number: 12080722
    Abstract: A pixel array, a display panel, and a display device are provided. The pixel array includes a first pixel electrode, a first data line, and a second data line. The first pixel electrode includes a first side and a second side opposite to the first side. The first data line is electrically connected to the first pixel electrode. The first data line is adjacent to the first side of the first pixel electrode and extends to the second side. The second data line is adjacent to the first data line. At least a portion of the second data line is disposed between the second side and the first data line. The first data line and the second data line are respectively configured to transmit signals with opposite polarities.
