Patent number: 12198651Abstract: 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.Type: GrantFiled: November 15, 2021Date of Patent: January 14, 2025Assignee: TCL China Star Optoelectronics Technology Co., Ltd.Inventors: Hongquan Wei, Yichen Bai, Yanxi Ye
